Solution

1. Preparation

Gather all necessary tools and materials.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Tools Required: Jack, jack stands, torque wrench, tire pressure gauge, wheel balancer, alignment tools.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Visually inspect each tire for signs of damage or uneven wear.
Check tire pressure using a tire pressure gauge; inflate to the recommended PSI if necessary.

3. Wheel Balancing

Mount the tires on a wheel balancer.
Spin the tires and observe for any imbalances.
Adjust weights as needed to achieve balance; re-check for accuracy.

4. Suspension and Alignment Check

Raise the vehicle using a jack and secure with jack stands.
Inspect control arms, bushings, and other suspension components for any signs of wear or damage.
If necessary, replace any worn components.
Perform a wheel alignment using alignment tools to adjust angles per manufacturer specifications.

5. Brake System Inspection

Remove the wheels and inspect brake rotors for warping or uneven wear.
If rotors are warped, replace or resurface them.
Reinstall wheels and torque lug nuts to the manufacturer's specifications.
