Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during repairs.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the drain plug using a socket set and allow the fluid to completely drain.
Inspect the fluid for metal shavings that indicate wear.

3. Inspect and Replace Worn Components

Inspect Differential Gears:
- Remove the differential cover using a socket set.
- Check the gears for pitting, scoring, or excessive wear.
Replace Worn Bearings:
- If wear is found, remove the differential assembly and replace the bearings using a bearing puller.
- Ensure the new bearings are properly seated and lubed.

4. Reassemble Differential

Clean the differential cover and apply a new gasket or sealant.
Reinstall the differential cover and torque the bolts to manufacturer specifications (refer to the service manual for the specific torque value).
Refill the differential with the appropriate fluid type (typically 75W-90 gear oil).

5. Reconnect Battery and Test

Reconnect the battery.
Perform a test drive to ensure the noise is resolved and check for any leaks around the differential.
