Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secure with jack stands.
Disconnect the battery to prevent electrical issues.

2. Differential Fluid Change

Sub-steps:
1. Remove the drain plug and drain the old fluid into a suitable container.
2. Inspect the old fluid for metal shavings or debris which may indicate internal damage.
3. Replace the drain plug with a new washer and torque to the manufacturer’s specifications (typically around 30 lb-ft).
4. Remove the fill plug and utilize a fluid pump to refill the differential with the recommended fluid (typically 75W-90 gear oil) until it reaches the fill hole.

3. Inspect and Replace Differential Components

Sub-steps:
1. Remove the rear differential assembly if needed, following the service manual instructions.
2. Inspect the ring and pinion gears for wear or damage.
3. Check the bearings and shims for proper clearance and replace if necessary.
4. Reassemble the differential with new seals and gaskets, ensuring all components are torqued to specifications.

4. Reassemble and Test Drive

Sub-steps:
1. Reinstall the differential assembly back into the vehicle.
2. Reconnect all components, including driveshaft and suspension parts.
3. Reconnect the battery and lower the vehicle.
4. Take the vehicle for a test drive to ensure the noise is resolved.
