Differential Service in Chesapeake, Virginia – What You Need To Know

Scratching your head? Don’t worry, if you don’t know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Chesapeake, Virginia, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Chesapeake motorists might even have two or three.

Not surprisingly, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner near your Chesapeake, Virginia home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, Chesapeake motorists’ tires would scrub and hop along the pavement during turns like the early cars.

Ever noticed the big bulge in the middle of the rear axle on trucks? That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complex to some Chesapeake auto owners – but you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but- we’ve said it before – they need to be properly lubricated in order to stay strong. So from time to time, you need to schedule a differential service in Chesapeake at West Service Center, Inc.. The used fluid is drained and replaced with clean fluid. Some manufacturers advise certain differentials to have special additives installed.

Get your differential serviced at West Service Center, Inc. in Chesapeake.

Recommendations for the time and mileage interval for servicing your differential can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your Chesapeake, Virginia West Service Center, Inc. service advisor or your auto manufacturers owner’s manual for recommendations.

How and where you drive in Chesapeake will have an essential impact as well. If you drive on dirt roads or through streams around Chesapeake, Virginia, you’ll need to service your differential much sooner than if you always stay on Virginia expressways.

Drive Train Service in Chesapeake at West Service Center, Inc.

The drive train in your vehicle includes all the critical components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.

Let’s start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.

West Service Center, Inc. service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise in your wheel wells when you turn, you may have a damaged CV joint. A damaged CV joint should be replaced.

Rear-wheel drive vehicles generally have a transmission in the front of the car and the differential in the back. A driveshaft (it looks like a long tube) connects the transmission to the differential. Some vehicles may have a two-piece driveshaft, which are connected to the differential with universal joints or U-joints. Again, the differential is connected to two half-shafts that go out to the wheels.

West Service Center, Inc. service on the drive train on a rear-wheel drive vehicle starts with servicing the differential. It will need its fluid drained and replaced regularly. The seals on the axles should also be inspected for wear or leaks. Leaking or damaged seals may mean the axle needs to be serviced as well. Also, U-joints can wear out. If you hear clunking or feel a jolt when you shift into drive or into reverse, it could indicate a driveline problem.

All-wheel drive vans provide power from the transmission to all of the wheels, instead of just to the front or rear. The advantage is that the vehicle can adapt to different driving conditions and transfer more power to the front or back wheels as needed. The disadvantages are that the driveline is more complicated, and the vehicle weighs slightly more.

Many all-wheel drive vehicles are based on a front-wheel drive set-up. They also have a differential in the rear and one in the center of the vehicle that allows power to transfer to the front and rear. A shaft runs from the transfer case to the center differential, and another from the center differential to the rear differential.

Servicing an all-wheel drive at West Service Center, Inc. involves servicing ALL of the differentials and inspecting the joints and seals for wear, leaks or damage.

Four-wheel drive vehicles are rear-wheel drive vehicles that have an option to transfer power to the front wheels. In other words, they can be driven as either rear-wheel or four-wheel drive vehicles. These vehicles are specifically designed for the harsh driving conditions Chesapeake motorists encounter off-road. The driveline in a four-wheel drive vehicle is similar to that of an all-wheel drive vehicle. The center differential, however, is a transfer case. Maintenance requires servicing both of the differentials and the transfer case, as well as an inspection of the joints and seals.

Chesapeake car owners would be wise to check with their owner’s manual for recommendations on how often to service their van drive train. It’s also good auto advice to check with your honest West Service Center, Inc. technician as well. You may live in an area in Virginia where weather or driving conditions require more frequent servicing of the drive train.

If you drive off-road, it is vital to service your driveline more often frequently than the typical recommendation. Conditions encountered off-road around the Chesapeake area are particularly hard on your driveline.

Good car care at West Service Center, Inc. in Chesapeake always includes taking care of your driveline. Without it, your van becomes a very large paperweight.

West Service Center, Inc. is located at 904 Cavalier Blvd in Chesapeake. We provide comprehensive auto repair and maintenance services for residents of Chesapeake, Norfolk, Suffolk, Portsmouth and Chesapeake.

Drive Train – What You Need to Know In Chesapeake

One Chesapeake automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Chesapeake, 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.

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 Chesapeake 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 Chesapeake 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 axle is damaged or leaks, the axle will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Chesapeake 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 Chesapeake 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 West Service Center, Inc. if any of it needs to be done now.
