Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to the recommended psi as indicated on the driver's door jamb.

3. Inspect and Replace Tires (if necessary)

Remove the wheel covers or hubcaps (if applicable).
Use a lug wrench to loosen and remove the wheel lug nuts.
Inspect the tires for signs of uneven wear or damage; replace if needed.
Reinstall the tires, torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Wheel Balancing

Remove the wheel from the vehicle.
Mount the wheel on a wheel balancer.
Add or remove weights as indicated by the balancer to achieve proper balance.
Reinstall the wheel on the vehicle.

5. Check Wheel Alignment

Use an alignment tool or take the vehicle to a professional for alignment services.
Make necessary adjustments to camber, caster, and toe settings as per manufacturer specifications.

6. Inspect Suspension Components

Visually inspect shocks and struts for leaks or physical damage.
Check control arms and bushings for wear; replace any damaged components.
Tighten any loose bolts or connections.
