Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles.

2. Tire Inspection and Pressure Adjustment

Use a tire pressure gauge to check the tire pressure; adjust to recommended specifications if needed.
Inspect each tire for bulges, cuts, or uneven wear. Replace any damaged tires.

3. Wheel Lug Nut Torque Check

Using a torque wrench, check the torque of the lug nuts according to the manufacturer's specifications (typically around 80-100 ft-lbs).
Tighten any loose lug nuts as necessary.

4. Tire Balancing

Remove the wheels from the vehicle using a jack and jack stands.
Take the wheels to a tire shop or use a tire balancing machine to balance each wheel.
Reinstall balanced wheels onto the vehicle.

5. Suspension Inspection

Inspect shock absorbers and struts for leaks or damage; replace if necessary.
Check control arms and bushings for wear; replace worn components.

6. Alignment Adjustment

Use an alignment machine to check and adjust the wheel alignment according to manufacturer specifications.
Make necessary adjustments to camber, caster, and toe settings.
