The differential is responsible for directing the power generated from your engine to your wheels and providing a smooth turning motion as well as the traction needed to move safely. Grinding noises, vibrations, and fluid leaks are common signs that your differential may need service. Our experienced certified technicians have extensive knowledge and experience in diagnosing and servicing all types of differentials for most vehicles, including cars, trucks, and sport utility vehicles.

Rear vs. Front Differential Repair Services

Identifying differences in how rear and front differentials function will help identify potential problem areas that require attention.

Rear Differential Repair:

Common in rear-wheel-drive vehicles and trucks Handles the majority of torque transfer, making it prone to wear Services include gear replacement, fluid change, and housing reseal

Front Differential Repair:

Found in front-wheel and all-wheel-drive vehicles Requires regular fluid changes to prevent overheating Includes bearing replacement, seal service, and alignment adjustments

In some vehicles equipped with an AWD system or a 4-Wheel Drive system, the front and rear differentials share equal responsibility for distributing the same amount of torque to each axle. To provide assurance that all components are working as designed, our technicians use a coordinated inspection process to evaluate all aspects of the drivetrain.

Causes of Differential Noise & Vibration

Unusual noises or sensations while operating your vehicle may be an indication of a differential issue. Identifying and resolving such issues at an early stage will avoid having to spend money on expensive repairs in the long run.

The common reasons for differential problems are as follows:

Worn-out bearings or gears – These make unusual whining or grinding sounds when you accelerate or turn.
Lack of proper fluid levels or contaminated fluid – This reduces the lubrication between the moving parts, creating excessive heat and metal-to-metal contact.
Leaks in the seals – Allow the gear oil to leak out, resulting in the differential overheating.
Misaligned gears – Make unusual humming or clunking sounds when you accelerate.
Worn ring and pinion gears – Results in extreme whining and/or grinding sounds from the rear of the vehicle.
Normal wear and tear – As time goes by, the internal components of the differential wear out and need to be maintained.

If your vehicle is exhibiting any of the above signs, you should have it checked as soon as possible. At our shop in Kingsport, TN, we perform precise diagnostic testing and complete repairs quickly to remove the noise and restore performance to your vehicle.

FAQs

Why are differentials so expensive?

The Differential is an extremely sophisticated and complex mechanical assembly using precision gears and bearings, which, in order to fix, requires special parts and labor. In addition to the type of vehicle you own, the amount of money you will need to spend for replacement/repair depends upon the type of differential your model uses (some models use limited-slip or advanced differentials), which are much more expensive to rebuild/replace than standard units.

What causes a diff to fail?

Your differential can fail due to poor/dirty fluid, worn bearings, or poor maintenance. Excessive towing, aggressive driving, and ignoring early warning signs of failure can significantly accelerate wear on your differential’s gears and internal components. Regular maintenance inspections, along with timely fluid changes, will help prevent failure.

What happens if you never change your diff fluid?

If you do not change your differential fluid, over time dirt, metal shavings, and heat will begin to break down your lubricant, allowing your gears and bearings to suffer internal damage. As a result of this failure, you may be left with costly repairs to your differential, including replacing your gears and/or your entire differential. Changing your differential fluid routinely ensures that your gears and bearings continue to be protected and your vehicle continues to run properly.
