Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.
Disconnect the battery if necessary for safety.

2. Tire Inspection and Rotation

Remove the wheel covers or hubcaps if applicable.
Use a lug wrench to loosen and remove the lug nuts.
Inspect the tires for uneven wear or damage and rotate them if necessary.
Reinstall the lug nuts and torque them to the manufacturer's specifications (typically 75-85 ft-lbs).

3. Wheel Bearing Replacement (if needed)

Remove the wheel and brake caliper (use a socket set).
Detach the brake rotor to access the wheel bearing.
Use a bearing puller to remove the old wheel bearing.
Clean the hub assembly and install the new bearing, ensuring it is pressed in evenly.
Reassemble the brake rotor and caliper, and secure with the appropriate torque.

4. Additional Component Inspection

Inspect the CV joints and axle shafts for any signs of wear or damage.
Replace any damaged components as necessary.

5. Final Assembly

Reinstall the wheel and tighten the lug nuts to the specified torque.
Lower the vehicle and remove any jack stands used during the repair.
