Transmission Care In Lakewood CO

February 2nd, 2010 by randypickering

Call Pickering’s Auto Service Center to make an appointment to check your transmission in Lakewood.
90 Wadsworth Blvd
Lakewood, CO 80226

Do you have any plans around Lakewood CO for the weekend? Maybe you and some friends and are taking the boat up to the lake. Maybe you’ll be having a lot of fun water skiing and doing a little fishing.

You got the boat all ready. It’s all gassed up. You packed lots of snacks and the cooler’s stocked – ready to go.

How about your tow vehicle? It has plenty of gas and you’ve even vacuumed it out, but is your auto maintenance up to date?

Stop and think. You’ll have some heavy traffic on your way out of town. Hilly terrain as you get to the lake. Some dirt roads – and it may be hot weather. And all the time you’re going to be towing around several thousand extra pounds.

That all adds up a lot of severe strain on your engine, brakes and transmission. Your transmission’s going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What’s a fun little blast to the lake for you is really severe duty for your transmission.

It’s important that you have enough transmission fluid. If you’re running low, the transmission will run to hot and won’t have the protection it needs to cope with the added stress of towing.

And if it’s time for a transmission service, you really should have it done at Pickering’s Auto Service Center before your trip. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced on schedule to make sure it runs efficiently.

Automatic transmissions contain a maze of passages that the fluid has to pass through to keep it shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems. Neglect your transmission for too long, and it can fail. Believe us – you don’t want to pay for a major transmission repair.

You know, most of us in Lakewood CO do a lot of our driving under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips or driving in very hot or very cold weather. Also, dusty roads, city driving around Lakewood, and basically any driving that’s not at highway speeds or under ideal conditions is severe driving. We all need to think about whether or not we need to follow the severe service schedule.

So, consider going in for a full service oil change before you leave for the lake to make sure everything has been looked at. Ask for a trip inspection while you’re at it. Your Lakewood CO service technician at Pickering’s Auto Service Center can check your belts and hoses and let you know if your brakes are in good shape.

Don’t forget the sunscreen. And to thank your Lakewood service technician, how about bringing him back a nice trout?

Fuel Filter Service in Lakewood CO

January 26th, 2010 by randypickering

There are a surprising number of small, inexpensive parts that can lead to expensive engine damage when they fail. It doesn’t seem right.

Fortunately a lot of those things can be taken care of in routine maintenance. They may not be easy to remember, because it is a long list, but your service center at Pickering’s Auto Service Center can help you know what’s scheduled to be taken care of.

Some of us in Lakewood CO really don’t look forward to going in for an oil change and then getting a list of the other things the manufacturer recommends.

But automotive maintenance is all about prevention, and addressing small problems before they get big. Let’s take the fuel filter for example.

You may not know this but the median age for private vehicles on our Lakewood CO roads is over nine years. When cars get older, five years or so, they’ve accumulated a lot of dirt and rust in their gas tanks. If that dirt gets into the engine it can cause thousands of dollars worth of damage. So somewhere between that dirty gas tank and the price of a great vacation – is the lowly fuel filter: a very inexpensive part that doesn’t cost too much to replace. And your car’ll just run better too.

A clogged fuel filter can’t let enough fuel through. You might notice at first that your car is running fine around town, but struggles or sputters on the Lakewood CO freeway or when you accelerate. Enough fuel can’t get through to meet the demands of higher speed. If it gets bad enough your engine might just shut off or not start at all, which could be dangerous.

Some fuel filters have a bypass. When they get clogged, they allow dirty fuel to move around the filter element so dirt ends up in the engine. We’ve already talked about how expensive that can be.

The fuel filter is even very important for newer cars. The fuel is still dirty even if there isn’t rust in the tank. It’s just that the fuel filter will need to be changed more frequently as the vehicle gets older.

How often should you change your fuel filter? Check your owner’s manual. Your Lakewood CO service advisor at Pickering’s Auto Service Center can tell you as well. It’s usually around thirty thousand miles or so. Ask if it’s time for a full fuel system cleaning as well. They often go hand in hand.

It’s good to know that your Lakewood CO service center has your back. When you’re motivated to maintain your vehicle’s performance and to reduce operating costs, you’ll think of Pickering’s Auto Service Center as your ally – and maybe even your memory.

Diesel Maintenance For CO

January 21st, 2010 by randypickering

At Pickering’s Auto Service Center we hear from a lot of people who are excited about the new diesel engines that will soon be available in passenger cars and SUV’s. But our CO friends are often curious about the preventive maintenance requirements. People may not know that diesel engines have long been used extensively in Europe and Asia. In fact, in some markets, there’re nearly as many diesel powered passenger cars as there are gasoline.

Here’s who’s announced or is expected to announce new diesels for North America: BMW, Mercedes, Audi, Volkswagen, Nissan, Honda, Toyota, Hyundai and Subaru. Of course, the US auto makers will be expanding their diesel offerings as well. Diesels will become a very big deal here in CO.

You may ask, why has it taken so long getting to CO and North America? There are a bunch of reasons like fuel tax policies and such, but the biggest hurtle was that CO diesel fuel had a high sulfur content – too high for the latest generation of highly refined diesel engines. Recent government mandates to remove sulfur now opens up CO to the engines the rest of the world’s been enjoying for a long time.

Why are diesels so popular worldwide? Well, for starters, diesels get up to 30% better fuel economy than gas engines. And they last a lot longer. And modern diesel engines are refined, quiet and powerful – and there’s none of that black smoke we used to see.

Some people may think that diesels create more pollution. But, you need to rethink diesels. Environmental pollution standards for diesel cars and light trucks are scheduled to be as strict as they are for gasoline vehicles. A modern diesel engine is as clean as a gas engine.

You may also have heard a lot in the news about bio-diesel. The exciting thing about diesels is that they’re not limited to fossil fuels. They can run on fuel made from vegetable oil. There are refineries that make diesel fuel from cellulosic waste like woodchips from lumber mills. There’s even this cool new process where a special strain of algae is used to convert carbon dioxide, water and sunshine into bio-diesel. That’s still a ways off, but you can see that diesel can become a sustainable source of fuel.

And, there are not a lot of trade off’s with diesel in terms of performance. A modern passenger car diesel is very smooth, quiet and quick. Most folks wouldn’t notice any difference. For those who tow trailers and haul heavy loads, diesels will be an improvement.

Now diesel engines are heavy duty, so they cost more than gas engines. But they get better fuel economy – so the break-even point is largely dependent on the difference between CO gas and diesel prices at the pump and how many miles you drive. And diesels have a higher resale value.

Now, let’s get back to diesel maintenance. You have to keep in mind that most of the new diesels are just coming in, or will be over the next couple of years, so we don’t have the maintenance schedules to make direct comparisons yet.

But going off what we already have in CO, we can expect fluid drain intervals to be similar to gasoline engines. Diesels do require very clean fuel, air and oil, so their filters are much higher capacity than gasoline filters and cost more. The engine air filter needs to be changed more frequently as well.

Repair costs are similar. As with gasoline engines, proper maintenance is the key to long engine life and to avoiding repairs. So pretty much what we have come to expect with gas vehicles; coolant system service, transmission service, power brakes, power steering, differential, filters, fuel system, and so on. And the payoff for you, if you’re the kind that likes to keep your vehicles for a long time, is that a properly maintained diesel engine can last for hundreds of thousands of miles.

Timing Belt Replacement in Lakewood

December 31st, 2009 by randypickering

Today we want to talk about timing belts. They’re something that many Lakewood drivers don’t know much about and yet your vehicle won’t run if it’s broken – and it could cause many thousands of dollars damage if it does break. A broken timing belt is usually a tale of woe. Even though timing belt replacement is scheduled in the owner’s manual, it’s not the kind of thing that most Denver car owners remember because it’s not well understood.

Let’s review what a timing belt does. As you know, the engine’s power is generated in the cylinders. A piston rides up and down in the cylinder. During the first down stroke, an intake valve at the top of the cylinder opens and air and fuel is drawn into the cylinder. Then the piston returns to the top, compressing the fuel and air mix. At the top, the spark plug fires, igniting the fuel pushing the piston down in the power stroke. As the piston once again returns up in the final stroke of the cycle, an exhaust valve opens at the top of the cylinder and the exhaust is pushed out. The timing belt is what coordinates the opening and closing of the intake and exhaust valves. It’s called a timing belt because the valves have to open and close at just the right time.

Now, not all Lakewood and Littleton vehicles have timing belts. Some have timing chains. Like the name implies, they use a chain rather than a belt to perform the function. It used to be that most engines used timing chains, which are extremely durable. Manufacturers started using belts rather than chains to save money in the manufacturing process. So now we’re left with a component that can break. They sort of shifted the problem to us. There are two broad categories of engine design: interference and non-interference. If the timing belt on a non-interference engine breaks, the engine simply stops running. That could be very dangerous depending on where you are at the time, but it causes no internal engine damage.

Interference engines, on the other hand, will get real messed up when the timing belt breaks, because the valves will actually fall down into the path of the pistons. Things get chewed up when that happens and it’ll cost thousands to repair the engine.

So, what are the warning signs? Unfortunately, there really aren’t any. There aren’t tell-tale sounds. In some vehicles, a technician from Pickering’s Auto Service Center may be able to see part of the belt for a visual inspection, but many have a cover that’s in the way. The reality is that if the belt slips even one notch, it might as well be broken for all the damage it’ll cause. There’s no middle ground.

So how can we avoid these problems? Simply replace the timing belt when your owner’s manual calls for it. It can be 60,000 miles; it might be 90,000 or 100,000 miles. The point is, if you have 60,000 or more miles, ask your Pickering’s Auto Service Center service advisor right away if your manufacturer requires a timing belt replacement.

Or call us at 303-237-7717

Sometimes you can go quite a while without a failure, but we’ve seen them happen within a couple of oil changes of being due. It’s not worth the risk.

What does it cost to replace a timing belt in Littleton or Golden? Well, that really depends on what kind of car you have. I can tell you that it’s usually not very easy to get to the timing belt – you often have to remove some accessories to get at it. It isn’t a cheap procedure, but it’s a fraction of what it could cost to repair the damage caused by a failure.

At Pickering’s Auto Service Center we’re all about trying to prevent costly repairs, keeping you and your passengers safe and increasing your driving enjoyment. Thanks to AutoNetTV for their great auto video tips.

What To Do In Case Of An Accident in Denver

December 22nd, 2009 by randypickering

Screeching tires, crunching metal – it’s an accident! If you’ve ever been in a car accident in Denver , even a minor one, you know how upsetting it can be. It’s hard to think straight and know what to do.

Let’s review what you should do in case of an accident:

When an accident occurs, you should always stop. Leaving the scene of an accident in Lakewood is considered a crime – even if it’s not your fault. And hit and run penalties are fairly severe, possibly resulting in steep fines, loss of your CO driver’s license or even jail time.

Your jurisdiction may require that you try to help someone who is injured by calling for help or performing first aid if you are able. Warn other Littleton and Golden motorists by putting out flares, using your flashers or lifting your hood. Call Denver emergency services as soon as possible. Tell the operator if medical or fire help is needed.

Always file a Lakewood police report. It’s tempting to skip this if everything seems to be ok. But without a police report, the other guy can say whatever he wants about the accident later, and you’ll not have an objective report to help defend yourself. Discuss the accident only with the police. Emotions are strong after an accident and we naturally want to talk about it – don’t. Never admit fault or guilt to anyone including the police officer. Sometimes we may feel at fault, but in the eyes of the law, the other guy is responsible.

Truthfully give the officer the facts: such as “I was going thirty miles an hour” not “I wasn’t speeding”. Remember, anything you say to the officer or anyone else can be used against you.

Also get the officer’s name and ID number and ask where you can get a copy of the accident report.

Get the facts on the driver and owner of the other vehicle:

  • Name
  • Address
  • Phone number
  • Date of birth
  • Driver’s license number and expiration
  • Insurance information

Also take down a description of the other Lakewood vehicle, license plate and vehicle identification number. Most CO auto insurance companies don’t record license plate numbers, so the VIN number is the best way to track the vehicle.

Ask witnesses, including passengers, to wait for the police. If they can’t wait, ask for contact information and request that they write a brief description of what they saw. If someone refuses to leave their name, write down their license plate number so the police can track them down later if necessary. Always call your insurance agent or your insurance company. Call or see a physician if you think you may have been injured. For vehicle repairs, call Pickering’s Auto Service Center at 303-237-7717

What Lakewood Automotive Service Consumers Should Know

December 16th, 2009 by randypickering

There are some things Denver consumers should know about Lakewood automotive service and repair. First and foremost, Pickering’s Auto Service Center cares about you and your family’s safety. And we really appreciate your business. Pickering’s Auto Service Center in Lakewood wants to build a trusting relationship that becomes the foundation for a mutually beneficial experience for years to come.

Building on that foundation, there are some things that would help you understand the auto service and repair business better. First, it can be really hard to fix cars. The days of shade tree mechanics are long gone. The majority of automotive systems are computerized. It takes a lot of training and very expensive equipment to diagnose and repair modern vehicles. The technicians that work for Pickering’s Auto Service Center need extensive computer training – not just how to run the diagnostic systems, but also searching for the right parts, networking with other technicians to help them with a difficult problem and pulling together a job order that makes sure that each step of the process is addressed.

The threshold for getting started as a technician gets higher all the time and there is a huge commitment to on-going training every year. This training takes time and money. It contributes to business overhead. The average Lakewood or Littleton driver may not realize the business and environmental regulations Pickering’s Auto Service Center must comply with. Of course that costs money too. Like any business, overhead is a big factor.

When you go into a Denver restaurant you don’t value the meal by what the food would cost at the grocery store. The restaurant has rent, wages, insurance, taxes, utilities, professional fees, equipment, supplies – you get the picture. The restaurant has to charge enough to not only pay for the ingredients, but for all these other things as well while making enough profit to remain in business. If you value the meal and are satisfied with your dining experience, you’ll come back and tell your friends.

It’s the same for Pickering’s Auto Service Center. The value of its service is not the cost of the parts they replace, but in your satisfaction with the results. If they deliver a good product at a fair price, Lakewood customers are happy to see them succeed as a CO automotive business.

Contact Pickering’s Auto Service Center to learn more about our extensive auto service training.
You can find us at:
90 Wadsworth Blvd
Lakewood, CO 80226
Or call us at 303-237-7717

Your Lakewood service center loves to see its customers whenever they come in, but they would much rather see them three or four times a year for routine maintenance than once a year on a tow truck. They want to work together with you to avoid breakdowns. Tell your Denver area friends and family to go in for their scheduled maintenance too. That lowers the service center’s marketing costs and helps keep its labor rates down. That’s good for everyone.

Pickering’s Auto Service Center appreciates this great review of automotive service from AutoNetTV.

Lakewood Drivers Severe Service Maintenance Schedules

December 10th, 2009 by randypickering

Your vehicle manufacturer publishes two auto maintenance schedules. The regular schedule and the severe service schedule. It’d be wrong for us to tell you that everyone in Denver always needs to follow the severe service schedule – but its wishful thinking to say that the regular schedule is always good enough for your sedan or SUV.

Contact Pickering’s Auto Service Center to learn more about Severe Service Requirements for your sedan or SUV
You can find us at:
90 Wadsworth Blvd
Lakewood, CO 80226
Or call us at 303-237-7717

At Pickering’s Auto Service Center we’ll give you the definitions and explain the issues, and you can be the judge. Most manufactures list the following as severe conditions:

  • Most of your trips are less than four miles.
  • Most of your trips are less than 10 miles and outside temperatures are below freezing.
  • The engine is at low speed most of the time – not on the highway.
  • You operate your vehicle in dusty areas.
  • You regularly tow a trailer or carry heavy loads.
  • Driving in very hot or very cold weather.

So think about your typical week. Do you live a block from a CO freeway on-ramp and enjoy a non-stop commute to work in Littleton or Golden? Or are you like the rest of us where 90% of our trips are on the severe service list?

The answer may be different at different times of the year and for the different drivers in your family. Think of the two service schedules as bookends. Let’s suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Look at your driving patterns and Lakewood road conditions and honestly evaluate which end of the spectrum you’re closer to.

If you have a job in a neighboring town such as Lakewood or Littleton and most of your commute is freeway miles, you may choose the regular service schedule for your car. On the other hand, if you live within a few miles of work and only get on the highway a handful of times every month, something closer to the severe service schedule is more appropriate.

Now why is this so important? Moisture builds up in the engine oil from normal condensation. Short trips around Denver or driving when it’s really cold means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil leads to oil sludge that gums up your engine and doesn’t let the oil protect it as well. That’s why you need to change your oil more frequently – to get the sludge out before it causes problems.

Towing, heavy loads and very hot CO summer weather means that your engine and transmission will operate at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Dusty conditions, which may extend also to areas with high air pollution, mean that fluids will get dirty faster and that filters will plug up and won’t work right.

All of these things can lead to premature wear and repairs down the road. They’ll also hurt your fuel economy. If you want some personalized advice, talk with your honest, and friendly. Pickering’s Auto Service Center service advisor. We can help you restore your vehicle to good working order and help you know the best schedule to follow. If you’re not sure, err on the side of protection.

Nitrogen Fill For Tires in Lakewood CO

December 2nd, 2009 by randypickering

So, everyone in the Lakewood CO area knows how great helium is – you know, party balloons, squeaky voices. But a lot of people around Lakewood still haven’t heard about the benefits of nitrogen in your tires, and how it can help your tires. Here’s some great advice from AutoNetTV, brought to you by Pickering’s Auto Service Center.

Nitrogen has actually been around for a long time in the Lakewood CO commercial sector, but it’s just starting to catch on for private vehicles in the 80226 zip code area.

Why nitrogen in your tires? Air is air, right? Actually, it turns out there is a difference.

Contact Pickering’s Auto Service Center to learn more about nitrogen in your tires
You can find us at:
90 Wadsworth Blvd
Lakewood, CO 80226
Or call us at 303-237-7717

The heart of the matter is maintaining proper tire inflation. When your tires are properly inflated, they last longer, handle better and more safely, and save you money at the gas pump.

The problem is that tires filled in Lakewood with regular air can lose a pound and a half of air pressure every month. This just happens as the oxygen in the tire seeps out. So if you don’t check your pressure for a month or two, well, you can be significantly low – low enough to actually affect your handling, shorten tire life and waste money at the fuel pump.

How does nitrogen help? Regular air contains about 78% nitrogen. Nitrogen is the largest molecule in air. It’s dry and non-flammable. Air also contains 21% oxygen, which is smaller and seeps out of the tire three to four times faster than nitrogen.

So, a tire filled with nitrogen at Pickering’s Auto Service Center will take about six months to lose as much pressure as regular air does in just one month. So it’s more forgiving for those who don’t check their pressure every week.

Also, when oxygen is at higher temperatures – like those inside your tire when you’ve been driving for awhile – it oxidizes the inside of your tire. Getting the oxygen out of your tire means that it’ll last longer.

Who’s using nitrogen? Well, let’s start with NASCAR and Indy. These racers like nitrogen’s ability to maintain consistent tire pressure and reduce tire temperatures under very demanding conditions. The US government requires all commercial aircraft to have nitrogen in their tires. NASA and the US Military use nitrogen. The mining industry has been filling those “humongous” tires with nitrogen for years. And semi trucks and trailers are starting to use nitrogen extensively.

You may have heard some detractors of nitrogen. But the studies and white papers from tire and vehicle manufacturers demonstrate that the technology really works.

In fact, a prominent consumer research group did a study where they filled some tires with air and some with nitrogen and stacked them outside for a year. They observed that the nitrogen filled tires did hold their pressure better, but they couldn’t see the economic benefit. But that particular test has very little to do with the real world. Most tires are actually holding up cars and they also get driven around and do a lot of work. So if nitrogen helps them last longer, saves gas and gives safer handling, it’s worth considering.

E-85 Fuel Safety Advice From Pickering’s Auto Service Center

November 25th, 2009 by randypickering

Today at Pickering’s Auto Service Center we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You’ve probably heard of E-85 gasoline being offered in the Denver area. Some newer vehicle models are specifically built to run on E-85 – the rest are not.

Does your vehicle use E-85 gasoline? Bring it down to Pickering’s Auto Service Center at 90 Wadsworth Blvd in Lakewood, CO 80226 to find out, or give us a call to make an appointment by calling 303-237-7717.

E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 15% ethanol, a grain-base alcohol, and 85% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower harmful exhaust emissions to our local Denver community.

All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Lakewood CO area does contain some ethanol. The problem comes when well meaning people without Flex Fuel certified vehicles put E-85 into the tank.

At a 15% concentration, the potential for problems arises. Because of the chemical differences between ethanol and gasoline, special seals and gaskets are needed for Flex Fuel vehicles in Lakewood CO. In a normal engine, the ethanol in E-85 gas will eat away important seals and gaskets. This leads to gas and oil leaks.

You can imagine the fire hazard caused by leaking gasoline. Fire fighting experts caution consumers to only use E-85 if they know they vehicle is certified to handle it. They expect vehicle fires to increase because of using the wrong fuel in non-Flex Fuel vehicles.

So are people who don’t have a Flex Fuel vehicle but use E-85 to help the environment actually putting themselves at risk? Yes. In fact, service and repair centers in Lakewood CO are being warned to purchase fire extinguishers that use the special foam needed to extinguish ethanol fires as a precaution in case starting-up an ethanol damaged engine leads to a fire.

Obviously, this isn’t something you want to have in your Lakewood CO garage at home, either. If you have a Flex-Fuel certified vehicle, feel free to protect the environment by using E-85 gasoline. If not – please do not use E-85 in an engine that’s designed to run on unleaded gasoline only. At Pickering’s Auto Service Center we are concerned about your safety. If you have questions or want to find out how to determine if your vehicle can safely use E-85, go to www.e85fuel.com for more resources.

Drive Train – What You Need to Know In Lakewood

November 18th, 2009 by

One Lakewood automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Lakewood, but they’re very important. First let’s define what the driveline is:

Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.

That’s not really a lot of components, but they handle the full force of the engine. Without the driveline you’re not moving. So we need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we’re going to have to over simplify a bit.

If you are ready to have your drive train looked at, give us a call:
Pickering’s Auto Service Center
90 Wadsworth Blvd
Lakewood, CO 80226
Call Us at 303-237-7717

Let’s start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel, come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.

So, driveline service would include properly servicing the transaxle and inspecting the CV boot to see if it’s torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner’s manual or check with your Lakewood service advisor.

On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Lakewood have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. You’ve probably heard the term ‘u-joints‘. These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected.

The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axel is damaged or leaks, the axel will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Lakewood service advisor for intervals.

Now let’s go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The vehicle may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.

Some all wheel drive vehicles are designed to work well off-road, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don’t work well on dry pavement when they’re in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.

Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is required as well as service to the center and rear differentials.

Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There’s a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So you need differential service for the front and rear differentials and for the transfer case as well.

The bottom line is that the maintenance schedules are in your owner’s manual. Your Lakewood service advisor can answer any questions you’ve got. If this is the first time you’ve heard some of this stuff – it’s time to ask someone at Pickering’s Auto Service Center if any of it needs to be done now.
