Differential Repair Addison, TX

Differential Repair & Service in Addison, TX

If you’ve started hearing whining, clunking, or grinding noises while turning or accelerating, your vehicle’s differential may be the problem. At Eagle Transmission and Auto Care of Addison, we provide professional differential inspection, repair, and service for front-wheel drive, rear-wheel drive, and four-wheel drive vehicles.

Our technicians are drivetrain specialists with the training and tools to accurately diagnose and repair differential issues — from basic gear adjustments to full replacements.

What Is a Differential?

The differential is a key component of your vehicle’s drivetrain. Its main job is to allow your wheels to rotate at different speeds while cornering, without slipping or skipping.

There are several types of differentials:

Open differentials
Limited-slip differentials
Locking differentials
Electronic-controlled differentials
Front, rear, and center differentials (on AWD or 4WD vehicles)

Each works slightly differently but serves the same purpose — keeping your vehicle stable and in control during turns and varying traction conditions.

Signs You May Need Differential Repair

Differential problems usually start subtly but become worse if left untreated. Common symptoms include:

Whining noise when accelerating or decelerating
Clunking or popping during turns
Fluid leaking from rear or front axle seals
Excessive vibration at highway speeds
Uneven tire wear
Difficulty turning, especially under load
Burning smell near axle housing

These signs often indicate worn gears, low fluid, damaged bearings, or failing internal seals.

What Causes Differential Damage?

Several issues can lead to a failing or noisy differential:

Old or contaminated gear oil
Low fluid levels due to leaks
Excessive towing or off-road use
Improper tire sizes or poor alignment
Normal wear and tear over time
Broken gears or chipped teeth
Failing pinion or carrier bearings

Driving with a damaged differential can lead to more serious drivetrain failures — including axle or transmission problems.

Gear Oil Service – Why It’s Critical

One of the most overlooked maintenance items is differential gear oil. Just like engine oil, it breaks down over time and can no longer protect gears from heat and friction.

We recommend:

Changing gear oil every 30,000 to 60,000 miles
Checking fluid regularly if towing or off-roading
Using manufacturer-approved gear oil only
Replacing gaskets and crush washers during every fluid change

Neglecting gear oil can lead to heat damage, gear wear, and complete differential failure.
