Solution

1. Preparation

Tools Required: Jack and jack stands, OBD-II scanner, torque wrench, fluid drain pan, and basic hand tools.
Safety Warnings: Ensure the vehicle is securely lifted and supported on jack stands before working underneath it.

2. Change Differential Fluid

Drain Old Fluid:
- Place a fluid drain pan under the differential.
- Remove the drain plug and allow the old fluid to completely drain out.
Inspect Drain Plug:
- Check the drain plug for metal shavings or excessive wear; clean and re-install if in good condition.
Replace Fluid:
- Reinstall the drain plug and tighten it to manufacturer specifications.
- Fill the differential with new fluid using the appropriate type specified in the owner’s manual (typically 75W-90 gear oil).
- Check fluid level via the fill plug until it reaches the correct level.

3. Replace Worn Components

Identify Worn Parts:
- If any components (e.g., bearings, seals, or gears) show signs of wear during inspection, note them for replacement.
Remove Differential (if necessary):
- Disconnect drive shafts and any electrical connectors.
- Remove mounting bolts and carefully extract the differential from the housing.
Install New Components:
- Replace worn bearings or seals with new parts as needed.
- Reinstall the differential housing, ensuring all bolts are torqued to specifications.
