Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety gear: wear gloves and safety glasses.

2. Tire Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount each wheel on a tire balancing machine.
3. Adjust weights on the wheel until balance is achieved as indicated by the machine.
4. Reinstall the wheels to the vehicle, torquing lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use an alignment tool.
2. Adjust camber, caster, and toe angles to manufacturer specifications.
3. Test drive to ensure that alignment is correct and vibrations have been resolved.

4. Suspension Inspection/Replacement

Sub-steps:
1. Visually inspect suspension components for wear or damage.
2. Replace worn bushings or shock absorbers if necessary.
3. Use a torque wrench to ensure all components are tightened to manufacturer specifications.

5. Wheel Bearing Inspection/Replacement

Sub-steps:
1. Jack up the vehicle and remove the wheel.
2. Check for play in the wheel bearing by attempting to move the wheel side to side.
3. If the bearing is worn, remove the hub assembly and replace the bearing.
4. Reinstall the wheel and torque to specifications.
