Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and safely jack it up.
Place jack stands under the vehicle for safety.

2. Drain Differential Fluid

Sub-steps:
1. Place a drain pan under the differential.
2. Remove the differential cover bolts using a socket set.
3. Carefully remove the cover and allow the fluid to drain completely.
Tools Required: Socket set, drain pan.

3. Inspect and Replace Gears/Bearings (if necessary)

Sub-steps:
1. Visually inspect the gears and bearings for wear or damage.
2. If damaged, remove the ring and pinion gears by unbolting them from the differential case.
3. Replace with new gears and bearings, ensuring correct alignment and torque specifications (check manufacturer's specs).
Tools Required: Torque wrench, bearing puller, socket set.

4. Clean and Reassemble Differential

Sub-steps:
1. Clean the differential cover and housing surfaces to remove old gasket material.
2. Apply a new gasket or sealant as required.
3. Reattach the differential cover and torque the bolts to specifications.
Tools Required: Gasket scraper, torque wrench.

5. Refill Differential Fluid

Sub-steps:
1. Using a fluid pump, refill the differential with the manufacturer-recommended fluid type.
2. Ensure fluid reaches the correct level (typically until it just starts to overflow at the fill hole).
Tools Required: Fluid pump.
