Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Fluid Change

Drain Old Fluid:
- Remove the drain plug using a socket set.
- Allow the old differential fluid to completely drain into a suitable container.
Replace Differential Fluid:
- Install the drain plug and torque to manufacturer specifications (typically around 30 ft-lbs).
- Remove the fill plug and use a fluid pump to add new differential fluid (consult the owner's manual for the correct type and quantity).
- Reinstall the fill plug.

3. Inspect and Replace Components

Remove the Differential Cover:
- If noise persists, remove the differential cover by unbolting it carefully.
- Inspect the gears and bearings for wear or damage.
Replace Worn Components:
- If any gears or bearings are damaged, replace them with OEM parts.
- Reassemble the differential and torque the cover bolts to specifications.

4. Test Drive

Conduct a test drive to ensure that the noise has been resolved.
Monitor for any signs of new noises or issues.
