Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Tires

Sub-steps:
1. Remove wheel covers or hubcaps if present.
2. Loosen lug nuts using a socket set but do not completely remove them.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Remove the lug nuts and take off the wheel.
5. Inspect the tire for damage or uneven wear.
6. If tire damage is found, replace the tire with a new one.
7. Reinstall the wheel and lug nuts, tightening them to the manufacturer's torque specifications (usually around 100-120 ft-lbs).

3. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Remove the wheel as described in the previous step.
2. Remove the brake caliper and rotor to access the wheel bearing assembly.
3. Inspect the wheel bearing for any signs of wear or roughness.
4. If the bearing is faulty, press out the old bearing using a bearing puller.
5. Install the new wheel bearing using a press, ensuring it is seated correctly.
6. Reinstall the rotor and brake caliper, ensuring all fasteners are tightened to specifications.
7. Reinstall the wheel and lower the vehicle, then torque the lug nuts.

4. Reconnect Battery

Reconnect the negative battery terminal once all repairs are completed.
