Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake and wear safety glasses.

2. Tire Balancing

Remove the wheel from the vehicle using a lug wrench.
Mount the wheel on a wheel balancer.
Follow the balancer's instructions to determine the weight distribution.
Attach the appropriate wheel weights to balance the tire.
Reinstall the wheel on the vehicle and torque lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).

3. Wheel Alignment

Position the vehicle on an alignment rack.
Attach alignment sensors to the wheels.
Follow the machine's instructions to check and adjust alignment settings (camber, caster, toe).
Adjust as necessary to meet manufacturer specifications.

4. Suspension Inspection and Replacement (if needed)

Visually inspect all suspension components for wear or damage.
If any parts (control arms, struts, bushings) are worn, remove them using appropriate tools (socket set, torque wrench).
Replace worn components with OEM or high-quality aftermarket parts.
Reinstall the components and torque to manufacturer specifications.

5. Final Checks

Recheck tire pressure after repairs.
Perform a test drive to ensure the vibration has been resolved.
