Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, level surface.
Secure the vehicle with wheel chocks and jack stands if lifting is required.

2. Tire Inspection and Replacement

Check Tire Condition:
- Inspect all tires for damage, bulges, or uneven wear.
- Measure tire pressure using a tire pressure gauge; inflate to the recommended PSI if needed.
Replace Tires:
- If tires are worn beyond safe limits, remove old tires using a tire iron.
- Install new tires, ensuring the correct rotation direction and seating.
- Tighten lug nuts to manufacturer’s torque specifications (typically 100-120 ft-lbs).

3. Wheel Balancing

Remove Wheels:
- Jack up the vehicle and remove the wheels using a tire iron.
Balance Wheels:
- Take wheels to a tire shop or use a wheel balancing machine.
- Add weights as necessary to achieve proper balance.

4. Suspension and Alignment Check

Inspect Suspension Components:
- Check bushings and struts for wear; replace any worn components.
- Ensure all nuts and bolts are tightened to the specified torque.
Perform Wheel Alignment:
- Use an alignment machine to check and adjust camber, toe, and caster settings according to factory specifications.

5. Driveshaft and CV Joint Inspection

Inspect Driveshaft:
- Check for any visible wear or damage; replace if necessary.
- Ensure driveshaft is properly aligned and secured.

6. Brake Inspection

Examine Brake Components:
- Check for warped rotors by inspecting for uneven wear.
- Replace any damaged or worn brake components.
