Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if performing any electrical inspections.

2. Tire Inspection

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Use a tire gauge to check tire pressures and inflate to recommended levels.
- Inspect tires for bulges, cuts, or foreign objects.
- Measure tread depth using a tread depth gauge; replace any tires with less than 3/32" tread.

3. Wheel Balancing

Sub-steps:
- Mount the wheel on a wheel balancer.
- Spin the wheel and allow the balancer to determine the weight distribution.
- Attach wheel weights as required to balance the wheel.
- Reinstall the wheel on the vehicle and torque lug nuts to manufacturer's specifications (typically around 90-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- Position the vehicle on an alignment rack.
- Adjust the camber, caster, and toe settings to the manufacturer's specifications.
- Test drive to confirm alignment adjustments are correct.

5. Suspension and Drivetrain Inspection

Sub-steps:
- Visually inspect all suspension components, including control arms, bushings, and struts for signs of wear.
- Check for play in wheel bearings by lifting the vehicle and shaking the wheel.
- Inspect the driveshaft for dents, bends, or excessive play.
