Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and raise the rear end securely using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Fluid Change

Drain Differential Fluid
- Locate the differential drain plug and remove it using a socket wrench. Allow the fluid to completely drain into a suitable container.
Inspect Fluid Condition
- Check the drained fluid for metal particles, which may indicate internal damage.

3. Replace Differential Fluid

Clean the Drain Plug
- Inspect and clean the drain plug, ensuring the gasket is intact or replace it if worn.
Refill Differential
- Reinstall the drain plug and tighten it to the manufacturer’s specified torque (typically 30 ft-lbs).
- Locate the fill plug and remove it. Use a funnel to fill the differential with the recommended gear oil (typically 75W-90).
- Fill until the oil reaches the bottom of the fill hole.

4. Inspect and Repair Internal Components (if necessary)

Remove Differential Cover
- If grinding persists, remove the differential cover by loosening the bolts with a socket wrench.
- Inspect the ring and pinion gears, bearings, and spider gears for wear or damage.
Replace Damaged Components
- Replace any worn or damaged gears or bearings. Ensure proper alignment during reinstallation.
- Reassemble the differential cover with a new gasket and torque the bolts to the manufacturer's specifications.

5. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle carefully.
