Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to avoid electrical issues.

2. Component Inspection and Replacement

Inspect and Replace Worn Components:
- Remove the wheel to access suspension components.
- Check control arms, struts, and bushings for wear or damage.
- If any components are damaged, remove them using a socket set and replace with new parts.
  - Tools Required: Socket set, torque wrench, pry bar
  - Safety Warning: Always wear safety glasses and gloves.

3. Tire Rotation and Alignment

Rotate Tires: If uneven tire wear is present, rotate tires to ensure even wear.
Perform Wheel Alignment:
- Use alignment equipment to adjust camber, caster, and toe settings to manufacturer specifications.
- Ensure all adjustments are locked in place as per specifications.
  - Tools Required: Wheel alignment machine
  - Safety Warning: Ensure vehicle is securely supported on jack stands before working underneath.

4. Test Air Suspension (if equipped)

Inspect Air Lines and Compressor:
