Solution

1. Preparation

Gather tools and parts needed for inspection and repairs.
Ensure the vehicle is on a level surface and safely secured (use jack stands).
Tools Required: Jack, jack stands, tire pressure gauge, socket set, torque wrench.

2. Tire Inspection and Repair

Check Tire Pressure:
- Use a tire pressure gauge to measure each tire's pressure.
- Inflate to the recommended PSI found in the owner's manual if necessary.
Inspect Tires:
- Visually check for any bulges, cuts, or foreign objects embedded in the tires.
- Replace any damaged tires as needed.

3. Suspension Component Inspection

Check Shocks/Struts:
- Remove any wheel covers or hubcaps if necessary.
- Inspect shocks and struts for leaks or physical damage.
- Replace worn or leaking shocks/struts with new ones.
Check Bushings:
- Inspect control arm and sway bar bushings for cracks or excessive wear.
- Replace any damaged bushings.

4. Wheel Alignment and Balancing

Alignment Check:
- Use alignment tools to check the angles of the wheels.
- Adjust the alignment as necessary, following manufacturer specifications.
Balancing Tires:
- Mount the tires on a wheel balancer to check for imbalance.
- Add weights as needed to ensure proper balance.
