Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, wheel balancer, alignment tools, and socket set.
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to reach the recommended PSI as indicated on the driver’s side door jamb.

3. Tire Inspection and Replacement

Remove the wheel covers or hubcaps if necessary.
Inspect each tire for visible damage or uneven wear; replace any damaged tires.
If tires are in good condition, proceed to balance the tires using a wheel balancer.

4. Wheel Balancing

Remove the wheel from the vehicle and mount it on the wheel balancer.
Follow the manufacturer's instructions to balance the wheel using weights.
Reinstall the balanced wheel on the vehicle, ensuring proper torque on lug nuts (typically 100-130 ft-lbs).

5. Suspension and Driveline Inspection

Lift the vehicle using a jack and secure it with jack stands.
Inspect suspension components for wear, and replace any worn parts (shocks, struts, bushings).
Examine the driveshaft for damage, and replace if necessary.

6. Alignment Adjustment

Use alignment tools to check the alignment settings.
Adjust the alignment as required to meet manufacturer specifications.
