1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to ensure safety while working on electronic components.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench
Check all rear suspension bolts and nuts for proper torque. Refer to the service manual for torque specifications.
Tighten any loose bolts as necessary to eliminate noise caused by movement in the suspension.

3. Replace Wheel Bearings (if faulty)

Tools Required: Jack and jack stands, wheel chocks, impact wrench, bearing puller, grease
Remove the rear wheel.
Use a bearing puller to extract the old wheel bearing from the hub.
Clean the hub area and install the new bearing, ensuring it is properly seated.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

4. Inspect and Repair Differential

Tools Required: Socket set, differential oil, leak sealant
Remove the differential cover if leaks or damage are noted.
Inspect the internal gears and bearings for any signs of wear or damage.
Replace any damaged components and reseal the differential cover with appropriate sealant.
Refill the differential with the manufacturer-recommended oil.
