Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Tire Inspection and Adjustment

Inspect Tires: Examine all tires for damage, uneven wear, or foreign objects.
Adjust Tire Pressure: Use a tire pressure gauge to check the pressure and inflate tires to the recommended PSI.

3. Wheel Balancing

Remove Wheels: Use a socket set to loosen lug nuts and remove the wheels from the vehicle.
Balance Wheels: Mount each wheel on a balancing machine to identify heavy spots. Add weights as required to achieve balance.
Reinstall Wheels: Torque lug nuts to manufacturer specifications (typically 100 Nm).

4. Suspension Inspection

Visual Inspection: Check control arms, tie rods, and bushings for cracks, wear, or damage.
Replace Damaged Components: If any parts are found to be worn, replace them with OEM or quality aftermarket parts.

5. Wheel Alignment

Set Up Alignment Equipment: Position the vehicle on an alignment rack.
Adjust Alignment: Follow specific manufacturer specifications for camber, caster, and toe adjustments as needed.

6. Test Drive

Conduct a test drive to ensure the vibration has been eliminated and that the steering feels stable.
