Solution

1. Tire Inspection and Maintenance

Sub-steps:
- Remove all four wheels from the vehicle using a jack and jack stands.
- Inspect each tire for uneven wear, bulges, or foreign objects.
- If any tires are damaged or excessively worn, replace them with new tires.
- Ensure all tires are rotated and balanced correctly.

2. Wheel Balancing

Sub-steps:
- Mount the tires onto a wheel balancing machine.
- Add weights to the rim as needed to achieve balance.
- Reinstall the balanced wheels onto the vehicle.

3. Suspension Inspection

Sub-steps:
- Visually inspect suspension components (shocks, struts, control arms) for damage or excessive wear.
- Replace any worn or damaged components using appropriate tools (e.g., socket set, wrench set).
- Ensure all bolts are torqued to the manufacturer’s specifications.

4. Wheel Alignment

Sub-steps:
- Use a wheel alignment machine to check alignment angles (camber, caster, toe).
- Adjust the alignment settings to match the manufacturer's specifications.
- Test drive the vehicle to assess any change in vibration.
