Solution

1. Tire Inspection and Adjustment

Inspect each tire for proper inflation; adjust to manufacturer specifications.
Check for uneven wear patterns; if found, rotate or replace tires as needed.

2. Wheel Balancing

Remove the wheel and tire assembly from the vehicle.
Mount the wheel on a tire balancing machine to identify imbalances.
Add or adjust weights as necessary to achieve proper balance.
Reinstall the wheel and torque lug nuts to the manufacturer's specifications (typically 100-110 ft-lbs).

3. Suspension Component Inspection

Lift the vehicle and support it securely with jack stands.
Inspect control arms, bushings, and struts for signs of wear or damage.
Replace any worn components following manufacturer guidelines.

4. Driveshaft and Axle Check

Inspect the driveshaft for any signs of wear, such as cracks or dents.
Check CV joints and axle shafts for play or damage.
Replace any damaged driveshaft or axle components as necessary.

5. Final Assembly and Test Drive

Reassemble any components that were removed during inspection.
Lower the vehicle and perform a test drive to verify that vibrations have been eliminated.
