Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.

2. Tire Inspection

Remove the wheel covers or hubcaps if necessary.
Check each tire for uneven wear patterns or damage.
Measure tire pressure using a tire gauge and inflate to manufacturer specifications if necessary.

3. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Mount each wheel on a wheel balancing machine.
Add weights as necessary to achieve proper balance; follow the machine’s instructions for placement.
Reinstall wheels and torque to manufacturer specifications (usually around 100-150 ft-lbs).

4. Alignment Check

Use an alignment machine to check the vehicle's alignment settings.
Adjust camber, caster, and toe angles as required to meet manufacturer specifications.

5. Suspension Inspection

Visually inspect shocks and struts for leaks or damage.
Check bushings and mounts for wear or deterioration; replace if necessary.

6. Drivetrain Inspection

Inspect driveshaft for any signs of wear or damage.
Check CV joints for play or tearing; replace if necessary.
