Solution

1. Preparation

Ensure the vehicle is parked on a level surface and turn off the engine.
Gather all necessary tools and parts.

2. Tire Inspection and Replacement

Sub-steps:
- Check tire pressure using a tire pressure gauge; adjust to manufacturer specifications.
- Inspect tires for bulges, cracks, or uneven wear. If damaged, replace with new tires.
- Use a torque wrench to ensure lug nuts are tightened to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a wheel balancing machine.
- Add weights as needed to achieve balance; re-install wheels on the vehicle.

4. Suspension and Drivetrain Inspection

Sub-steps:
- Inspect suspension components (control arms, bushings, shocks) for wear; replace any damaged parts.
- Check for play in the driveshaft and CV joints; replace any faulty components.

5. Wheel Alignment

Sub-steps:
- Use a wheel alignment tool to assess alignment angles.
- Adjust toe, camber, and caster angles to manufacturer specifications.
- Test drive the vehicle to confirm stability.
