What Does the Differential Do?
The differential is responsible for transferring engine power to your wheels while allowing them to rotate at different speeds. This is essential when turning, as the inside and outside wheels travel different distances. Without a properly functioning differential, your vehicle would experience hopping, binding, and unstable handling.
Different drivetrains use different differential configurations:
- Rear-wheel drive (RWD): differential located in the rear
- Front-wheel drive (FWD): differential integrated into the transaxle
- Four-wheel drive (4WD): front and rear differentials
- All-wheel drive (AWD): front and rear differentials with a transfer case
In all configurations, the differential plays a critical role in vehicle control, stability, and power delivery.
Benefits of Differential Repair & Maintenance
Differentials experience constant wear due to friction, heat, and load. Driving conditions such as gravel roads, off-road terrain, towing, or aggressive driving can accelerate wear. Routine differential service helps:
- Reduce excessive noise and vibration
- Prevent premature gear and bearing wear
- Improve traction and drivability
- Extend the life of the differential system
- Avoid costly differential failure and replacement
If you hear whining, grinding, clunking noises, or notice fluid leaks near the axles, your differential may need service.
Differential Fluid Change
Approximate Time: 60 Minutes
Differential fluid lubricates internal gears and bearings while reducing heat from friction. Over time, fluid breaks down and becomes contaminated, reducing its ability to protect the differential.
Why Differential Fluid Service Matters:
- Prevents overheating and excessive wear
- Reduces noise and vibration
- Protects gears and bearings
- Helps avoid complete differential failure
During a differential fluid change, old fluid is drained and replaced with manufacturer-approved fluid. Our technicians may also inspect seals and internal components for signs of wear.
Differential Service
Approximate Time: 30 Minutes
Differential service may include inspection, fluid condition evaluation, leak checks, and component assessment. Depending on your vehicle and driving habits, additional repairs or adjustments may be recommended to keep the differential operating properly.
Routine service intervals vary by vehicle and should follow manufacturer guidelines.
