Solution

1. Tire Inspection and Maintenance

Sub-steps:
- Remove the wheel covers or hubcaps (if applicable).
- Inspect tires for any bulges, cracks, or foreign objects.
- Check tire pressure using a tire gauge; inflate to recommended PSI if low.
- Rotate tires if uneven wear is present.

2. Wheel Balancing

Sub-steps:
- Mount the wheel on a tire balancing machine.
- Spin the wheel to determine the balance.
- Add weights as necessary to correct imbalance.
- Reinstall balanced wheels on the vehicle.

3. Suspension Inspection and Repair

Sub-steps:
- Visually inspect control arms, bushings, and struts for damage.
- Replace any worn suspension components with OEM or equivalent parts.
- Torque all bolts to manufacturer specifications.

4. Wheel Alignment

Sub-steps:
- Use a laser alignment tool to measure toe, camber, and caster angles.
- Adjust angles as needed to meet manufacturer specifications.
- Test drive to confirm straight tracking.

5. Brake System Check

Sub-steps:
- Inspect brake pads and rotors for wear.
- Replace any worn components to ensure braking is smooth and even.
- Check for any warped rotors that may cause vibration.
