Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent any electrical issues.

2. Drain Differential Fluid

Place a drain pan under the differential.
Remove the differential cover bolts using a socket set.
Carefully remove the cover and allow the fluid to fully drain.
Inspect the fluid for metal shavings or contamination.

3. Inspect and Replace Bearings (if necessary)

Remove the differential assembly from the housing by disconnecting the axle shafts and supporting the differential.
Inspect the pinion and carrier bearings for wear or damage.
If replacement is needed, use a bearing puller to remove the old bearings and install new ones using a press.
Ensure proper alignment and torque specifications for the bearings.

4. Reassemble Differential

Clean the differential cover and housing surfaces.
Apply a suitable gasket maker or install a new gasket depending on the design.
Reinstall the differential assembly, ensuring all bolts are torqued to specifications.
Reconnect the axle shafts.

5. Refill Differential Fluid

Fill the differential with the recommended fluid type (consult the owner’s manual for specifications).
Ensure the fluid level is at the correct height as per manufacturer guidelines.
Reinstall the differential cover and secure it with the appropriate torque.

6. Test Drive

Reconnect the battery.
Start the vehicle and perform a test drive to ensure the noise is resolved.
Listen for any abnormal sounds during acceleration and turning.
