4. Reinstall the wheels and hand-tighten the lug nuts.

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use an alignment machine.
2. Adjust camber, caster, and toe settings to match Tesla's specifications.
3. Ensure all adjustments are within the specified tolerances.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect struts, shocks, and bushings for wear or damage.
2. Replace any worn components as necessary.
3. Tighten all suspension bolts to the manufacturer's torque specifications.

5. Reinstall and Test

Sub-steps:
1. Reinstall the tires and torque lug nuts to the manufacturer's specifications.
2. Lower the vehicle and perform a test drive to assess handling and tire wear.
