Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and parked safely.
Disconnect the 12V battery to prevent electrical issues while working on the vehicle.

2. Tire Inspection and Replacement

Sub-steps:
- Inspect all tires for visible damage, bulges, or uneven wear.
- Measure tire pressure and adjust to the manufacturer’s specifications (usually found on the driver’s door jamb).
- If tires are worn or damaged, replace them with new tires of the same size and specification.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the hub using a socket set.
- Mount the wheel on a tire balancing machine to identify heavy spots.
- Add wheel weights as needed to achieve balance.
- Reinstall the wheel and tighten lug nuts to the manufacturer's torque specification (usually around 100-120 ft-lbs for most vehicles).

4. Wheel Alignment

Sub-steps:
- Use an alignment machine to check the alignment settings.
- Adjust caster, camber, and toe as necessary to meet OEM specifications.
- Perform a final check to ensure all settings are within acceptable ranges.

5. Suspension Inspection and Repair

Sub-steps:
- Inspect shock absorbers, struts, and other suspension components for wear.
- Replace any damaged or worn suspension parts with OEM or quality aftermarket parts.
- Ensure all bolts are torqued to manufacturer specifications.
