Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety gloves and goggles.

2. Tire Inspection

Remove wheel covers, if applicable.
Check each tire for bulges, cuts, or punctures.
Measure tread depth across the tire's surface to identify uneven wear.
If any tire is damaged or excessively worn, replace it.

3. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate tires to the recommended PSI found in the owner’s manual or on the driver's door jamb.

4. Wheel Alignment

Use an alignment tool or take the vehicle to a professional for alignment.
Adjust camber, caster, and toe settings as needed according to specifications.

5. Wheel Balancing

Remove each wheel from the vehicle.
Mount wheels on a balancing machine to check for imbalance.
Add weights as necessary to balance each wheel properly.

6. Suspension and Drive Components Inspection

Lift the vehicle using a jack and secure it on jack stands.
Inspect control arms, bushings, and struts for signs of wear or damage; replace if necessary.
Check the driveshaft and axles for any signs of damage or excessive wear; replace if needed.
