- Tire inflator
Ensure the vehicle is parked on a level surface with the engine off.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure each tire's pressure.
Inflate or deflate tires to the manufacturer-recommended pressure levels as indicated on the door jamb sticker.

3. Tire Inspection and Replacement (if needed)

Remove the wheels using a socket set.
Inspect each tire for uneven wear or damage; replace if necessary.
If tires are worn unevenly, consider rotating or replacing them.

4. Wheel Alignment

Mount the vehicle on an alignment rack.
Follow the manufacturer's alignment specifications to adjust the toe, camber, and caster settings.
Tighten all adjustment bolts to the specified torque values.

5. Suspension Component Repair/Replacement

Inspect suspension components for wear (e.g., bushings, shocks, struts).
Replace any worn components with new, high-quality parts.
Reassemble suspension components and ensure all bolts are torqued to specifications.
