Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, wheel balancer, alignment tools
Safety Warnings: Ensure the vehicle is on a flat surface. Use jack stands to support the vehicle securely.

2. Check and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure of each tire.
Adjust the pressure to match the specifications found in the owner's manual or on the driver’s side door jamb.

3. Inspect and Replace Tires (if necessary)

Remove the tires using a socket set.
Inspect for any visible damage, bulges, or uneven wear patterns.
Replace tires if any significant issues are found.
Reinstall the tires and torque the lug nuts to the manufacturer's specifications.

4. Wheel Balancing

Mount the tires on a wheel balancer.
Adjust weights as needed to ensure proper balance.
Reinstall the balanced tires back onto the vehicle.

5. Suspension Inspection and Repair

Inspect struts and shocks for leaks or damage; replace if necessary.
Check control arms and bushings for wear; replace any faulty components.
Reassemble any components that were removed during inspection.

6. Alignment Adjustment

Use alignment tools to check wheel alignment.
Adjust the alignment according to specifications, ensuring that all angles (camber, caster, toe) are within manufacturer tolerances.
