- Use a tire pressure gauge to check the pressure of all tires.
- Inflate or deflate tires to the recommended PSI as indicated on the driver’s door jamb.
Inspect Tire Condition:
- Remove the wheels using a jack and socket set.
- Inspect each tire for damage or excessive wear.
- Replace any tires that are worn beyond the tread wear indicators or damaged.

3. Suspension Inspection and Repair

Visual Inspection of Suspension:
- Check for worn or damaged components such as struts, shocks, and control arms.
- Look for any oil leaks around struts or shocks indicating failure.
Replace Worn Components:
- If any suspension parts are worn, replace them using a socket set and torque wrench.
