Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Use safety glasses and gloves.

2. Fluid Change

Drain Fluid:
- Place a drain pan under the differential.
- Remove the drain plug and allow the fluid to completely drain.
Inspect Fluid Condition:
- Check for metal shavings or discoloration in the old fluid.
Replace Fluid:
- Use the recommended differential fluid (check owner’s manual for specifications).
- Reinstall the drain plug and torque to manufacturer specifications (typically 30 ft-lbs).

3. Inspect and Replace Bearings

Remove Differential Cover:
- Drain any remaining fluid if necessary.
- Remove bolts holding the differential cover using a socket set.
Inspect Gears and Bearings:
- Check for wear on the ring and pinion gears, and inspect bearings for roughness or play.
Replace Bearings:
- If worn, use a bearing puller to remove old bearings.
- Install new bearings, ensuring they are properly seated.

4. Reassemble and Fill

Reinstall Differential Cover:
- Clean sealing surfaces and apply a new gasket or RTV sealant.
- Reinstall the cover and torque bolts to specified values.
Refill with Fluid:
- Remove the fill plug and add new differential fluid until it reaches the fill level.
