Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery (if electrical components will be accessed).

2. Differential Fluid Change

Tools Required: Socket set, drain pan, funnel, new differential fluid.
Remove the differential drain plug using a socket wrench and drain the old fluid into the drain pan.
Replace the drain plug and tighten to the manufacturer's specified torque.
Remove the fill plug and fill the differential with the correct type of fluid until it reaches the fill hole.
Replace the fill plug and tighten.

3. Inspect and Replace Worn Components

Tools Required: Jack stands, wheel chocks, torque wrench.
Raise the vehicle and secure it on jack stands.
Remove the rear wheels to access the differential and axles.
Inspect the CV joints for wear or damage; replace if necessary.
Check the differential bearings; if they are worn, proceed to remove the differential assembly.
To remove the differential, disconnect any mounting bolts, and slide the assembly out.
Replace bearings if needed and reassemble the differential using new gaskets or seals.

4. Reassemble and Lower Vehicle

Reinstall the differential assembly, ensuring all bolts are torqued to specifications.
Reattach the wheels and lower the vehicle back to the ground.
Reconnect the battery.
