Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Drain Differential Fluid

Tools Required: Socket set, drain pan
Remove the differential cover bolts using a socket.
Position the drain pan underneath and carefully remove the cover to allow fluid to drain completely.
Clean the mating surfaces of the differential and cover.

3. Inspect Components

Examine the gears, bearings, and housing for wear or damage.
Check for any visible scoring on the gears or abnormal wear on the bearings.
If damage is found, proceed to replace affected components.

4. Replace Bearings and Gears (if necessary)

Tools Required: Bearing puller, torque wrench
Use a bearing puller to remove the old bearings from the differential housing.
Install new bearings, ensuring they are pressed in evenly.
If gears need replacement, align and install new gears per manufacturer specifications.

5. Reinstall Differential Cover

Use a new gasket or sealant to ensure a proper seal.
Reattach the differential cover and tighten bolts to the manufacturer’s specified torque settings.

6. Refill Differential Fluid

Parts Required: Differential fluid (as per manufacturer specifications)
Fill the differential with new fluid until it reaches the fill level specified in the owner's manual.
Check for leaks around the differential cover and seals.
