- Replace any damaged tires as needed.
- Tools: Tire pressure gauge, tire iron.
Balance and Alignment:
- If tires are worn unevenly, have them balanced and aligned.
- Tools: Wheel balancer, alignment rack.

3. Wheel Bearing Inspection and Replacement

Check Wheel Bearings:
- Raise the vehicle and spin the wheel to listen for grinding noises.
- If roughness is detected, remove the wheel and inspect the bearing.
Replace Bearings:
- Remove the brake caliper and rotor to access the bearing.
- Use a bearing puller to remove the old bearing.
- Install the new bearing and reassemble components.
- Tools: Socket set, bearing puller, torque wrench.

4. Brake Component Inspection and Cleaning

Inspect and Clean Brakes:
- Remove the wheel and check the brake pads and rotors for wear.
- Clean any debris from the rotor surface.
Replace Worn Parts:
- If pads are worn below specifications, replace them.
- Tools: Brake caliper tool, socket set, brake cleaner.

5. Exhaust System Inspection and Repair

Inspect Exhaust Components:
- Check for loose or damaged pipes, hangers, and connections.
- Tighten loose components or replace damaged sections of the exhaust.
- Tools: Wrench set, exhaust clamps.

6. Suspension Inspection and Repair

Check Suspension:
- Inspect bushings, struts, and shock absorbers for wear.
- Replace any worn components as necessary.
- Tools: Jack stands, socket set.
