Drive Train Service in Suwanee at D.C. Auto

Posted May 23, 2017 7:43 AM

The drive train in your vehicle includes all the 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.

D.C. Auto 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.

D.C. Auto 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 vehicles 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 D.C. Auto 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 Suwanee drivers 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.

Suwanee auto owners would be wise to check with their owner's manual for recommendations on how often to service their vehicle drive train. It's also good auto advice to check with your friendly and knowledgeable D.C. Auto service advisor as well. You may live in an area in GA where weather or driving conditions require more frequent servicing of the drive train.


Good car care at D.C. Auto in Suwanee always includes taking care of your driveline. Without it, your vehicle becomes a very large paperweight.

Testimonials

  • Tom and the folks at D.C. Auto are simply the best. I've had a good bit of work done on my vehicles over the years and have always been treated well. They're honest, thoroughly explain the problem and charge reasonable prices; everything that you could ask for in a mechanic.
    -Tony D.

  • Been a DC Auto customer for almost 6 years now. Tom and his crew are top people - never disappointed. Always upfront and honest. Never "pushed" an addon or any sorts like that. One can only smile at a couple of pointed and personal reviews here. Never had "that" problem at DC Auto. Would recommend.
    -Raju S.

  • Always helpful, always cheerful. Honest estimates, and won't recommend work that isn't needed. If the problem falls outside of their ability, they will tell you right up front. I've taken multiple cars there for years and have never had a problem.
    -Charles P.

  • I have been going to DC Auto since it first opened. The staff is highly knowledgeable and courteous. Tom is one of the most honest men I know. He is highly ethical and never tries to "up-sell." The work is always superior. After all these years I can't see myself going to any other auto service company.
    -Louis C.

  • Awesome service at a great price. Always stands behind his work. Tom runs a great shop with great employees and always a smile and a story. Honest no gimmicks what all businesses should be.
    -Ron T.

  • I have been a customer with DC Auto for close to four years. I have NEVER had an unpleasurable experience. They know who I am when I pull in and do their very best to keep me and my family safe on the road! The crew at DC Auto is outstanding and the customer service is phenomenal.
    -Jessica R.

  • 5 stars...the guys at DC Auto have taken care of our family's cars since they opened. I just brought in my 2005 Honda Pilot with an oil leak. They found the leaky oil pan and replaced it. Not surprising on a 205,000 vehicle - drain plug was getting stripped out. She STill runs like new because I keep it maintained (at DC Auto). Fact is they do great work, they're honest and prices are good. No stupid high pressure. I trust them. Highly recommend.
    -Jerry M.

  • Fantastic service shop my husband and I (as well as several friends we recommended them to) have used for years. I know "honesty" isn't often a word associated with car mechanics but Tom and Rob have always shot us straight about our vehicles, and I know it to be true because several times, their advice to us has actually cost them a repair job (and saved us money). They typically get us scheduled same day or maybe the next, and the turnaround time is speedy. For hometown feel, honest opinions about your car, great service techs and reasonable prices, use DC Auto.
    -Megan H.

  • DC Auto is the what every car repair shop should be. These guys are great! They easily find what is wrong and fix it in a timely manner. The other reason I will refer anyone here is because their pricing is very reasonable. This place is better than others and WILL NOT overcharge you for every little and last thing. Go to this place for any car maintenance big or small. Tom and Robert in particular are who I would suggest, although everyone on staff is very good.
    -Dan C.

  • 10/10. Would recommend. Personable and knowledgeable mechanics that don't try to rip you off. Great quality work for reasonable pricing.
