Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery for safety when working on electrical components.

2. Tire Inspection and Replacement

Remove the affected wheel using a lug wrench.
Inspect the tire for uneven wear, bulges, or cuts.
If damage is found, replace the tire with a new one.
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Wheel Bearing Replacement (if needed)

Raise the vehicle and secure it with jack stands.
Remove the wheel and brake caliper for access to the bearing.
Remove the hub assembly by unbolting it from the steering knuckle.
Press out the old wheel bearing using a bearing puller tool.
Install the new wheel bearing and reassemble the hub assembly.
Reinstall brake caliper and wheel, torque lug nuts.

4. Drivetrain Inspection and Repairs

Inspect the driveshaft and differential for any signs of leakage or damage.
If any components are found to be worn or damaged, replace them according to manufacturer specifications.
Check and replace any worn out fluid in the differential or transmission as needed.
