Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Lift the vehicle and secure it on jack stands.

2. Fluid Inspection and Replacement

Tools Required: Socket set, drain pan, new differential fluid, funnel.
Sub-steps:
1. Locate the differential drain plug and remove it using a socket wrench.
2. Allow the old fluid to drain completely into a drain pan.
3. Inspect the drained fluid for metallic particles or a burnt smell, which indicates internal damage.
4. Replace the drain plug and torque it to manufacturer specifications (usually around 30-40 ft-lbs).
5. Remove the fill plug and use a funnel to fill the differential with new fluid until it reaches the fill hole.

3. Inspect and Replace Differential Components

Tools Required: Socket set, torque wrench, pry bar, replacement parts (bearings, seals, gears if necessary).
Sub-steps:
1. Remove the differential cover if necessary by unbolting it; check for signs of wear or damage.
2. Inspect the internal gears and bearings for any signs of damage or wear.
3. If damaged, remove the old bearings and gears using a puller.
4. Install new bearings and gears, lubricating them with differential fluid.
5. Reinstall the differential cover with a new gasket and torque to specifications (usually around 20-25 ft-lbs).

4. Test Drive

Sub-steps:
1. Lower the vehicle back to the ground safely.
2. Take the vehicle for a short test drive to listen for any remaining noises and observe handling.
