Solution

1. Preparation

Tools Required: Jack stands, wheel chocks, socket set, torque wrench, differential fluid.
Safety Warnings: Ensure the vehicle is on a flat surface, and use wheel chocks to prevent rolling.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the rear wheels for better access to the differential.

3. Fluid Change

Drain Differential Fluid: Place a drain pan under the differential. Remove the drain plug and allow the fluid to completely drain.
Inspect Fluid: Check for metal particles or discoloration in the fluid.
Replace Fluid: Reinstall the drain plug and fill with new differential fluid per the manufacturer’s specifications.

4. Inspect and Replace Bearings (if necessary)

Remove Differential Cover: Unbolt the differential cover and inspect the gears and bearings.
Check for Wear: Look for signs of scoring or pitting on the gears and bearings.
Replace Bearings: If worn, remove the old bearings using a bearing puller, and install new ones, ensuring they are properly seated.

5. Reassemble and Torque

Reinstall the differential cover and torque to the manufacturer’s specifications.
Reinstall the wheels and lower the vehicle.
