Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, tire balancer, alignment machine, impact wrench, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and engage parking brake before lifting.

2. Tire Inspection

Remove all four wheels using an impact wrench.
Inspect each tire for uneven wear, sidewall damage, or foreign objects embedded in the tread.
Replace any damaged tires as needed.

3. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the manufacturer's recommended PSI as found in the owner's manual or on the driver-side door jamb.

4. Wheel Balancing

Mount the tires on a tire balancer.
Identify and correct any imbalance by adding wheel weights as necessary.
Reinstall the wheels on the vehicle, ensuring to torque the lug nuts to the manufacturer's specification (typically around 100-110 ft-lbs).

5. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the camber, caster, and toe settings to align with manufacturer specifications.
Confirm that the vehicle is driving straight and not pulling to one side.

6. Final Inspection

Recheck the tightness of lug nuts post-repair.
Test drive the vehicle at high speeds to confirm that the vibrations have been resolved.
