Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in all four tires.
- Inflate or deflate tires as needed to meet the manufacturer’s specifications.
Inspect Tires for Damage:
- Examine each tire for uneven wear patterns, bulges, or cuts.
- Replace any tires that show significant damage or wear beyond acceptable limits.

3. Suspension Component Inspection and Replacement

Inspect Suspension:
- Lift the vehicle using a jack and secure it on jack stands.
- Visually inspect control arms, bushings, and struts for signs of wear or damage.
