Solution

1. Preparation

Ensure the vehicle is on a flat surface and securely elevated using jack stands.
Gather all necessary tools and safety equipment.
Disconnect the battery to prevent any electrical issues during the repair.

2. Drain the Differential Fluid

Place a drain pan under the rear differential.
Remove the differential drain plug and allow fluid to drain completely.
Inspect the fluid for metal shavings or debris, indicating internal wear.

3. Remove the Differential Cover

Unbolt the differential cover using a socket set.
Carefully pry off the cover, ensuring not to damage the gasket surface.
Clean the mating surfaces on both the cover and the differential housing.

4. Inspect Internal Components

Examine the gears, bearings, and other internal components for signs of wear or damage.
Spin the ring and pinion gears to check for roughness or binding.
Inspect the carrier bearings for play and ensure they are properly seated.

5. Replace Damaged Components

Replace any worn or damaged gears, bearings, or seals as necessary.
Reassemble the differential with new bearings or shims if required, following manufacturer specifications.

6. Reinstall the Differential Cover

Apply a new gasket or sealant to the differential cover.
Reattach the differential cover and torque the bolts to the manufacturer's specifications.

7. Refill Differential Fluid

Reinstall the drain plug and fill the differential with the recommended fluid using a funnel.
Ensure the fluid level meets the manufacturer's specifications.
