Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, OBD-II scanner, flashlight.
Safely lift and support the vehicle using jack stands.
Ensure the vehicle is on a level surface and secure with wheel chocks.

2. Check and Replace Differential Fluid

Tools Required: Socket set, drain pan, new differential fluid.
Drain the differential fluid by removing the drain plug and letting it fully drain into a pan.
Inspect the old fluid for metal shavings or debris indicating wear.
Clean the drain plug and replace it with a new washer if necessary.
Refill with manufacturer-recommended differential fluid (consult owner's manual for specifications).

3. Inspect and Replace Differential Bearings

Tools Required: Bearing puller, torque wrench, socket set.
Remove the differential cover to access the internal components.
Inspect the bearings for signs of wear or damage.
Replace any worn bearings with new ones, ensuring they are properly seated.
Reassemble the differential cover using a new gasket or sealant.

4. Reassemble and Test

Reinstall the differential cover and torque the bolts to the manufacturer's specifications.
Lower the vehicle and perform a test drive to confirm the noise has been resolved.
