Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, tire pressure gauge, Tesla diagnostic tool.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery for safety if working on electrical components.

2. Tire Inspection and Replacement

Inspect tires for any uneven wear, bulges, or cuts.
If tires are damaged or worn unevenly, replace all four tires to maintain balance.
Check that all tires are inflated to the recommended pressure (usually found on the driver’s door jamb).
After replacing tires, balance them using a tire balancing machine.

3. Suspension Component Replacement

If any suspension components are found to be worn or damaged, replace them accordingly.
- Sub-steps:
  1. Remove the wheel by loosening the lug nuts and then raising the vehicle.
  2. Inspect and remove damaged or worn components (e.g., bushings, control arms).
  3. Install new components, ensuring they are torqued to manufacturer specifications.
  4. Reinstall the wheel and torque the lug nuts to the specified value.

4. Driveshaft and Axle Inspection

If the driveshaft or axles are found to have play, consider replacing or repairing them.
- Sub-steps:
  1. Lift the vehicle and secure it on jack stands.
  2. Remove any protective covers to access the driveshaft and axles.
  3. Inspect for any signs of wear or damage (e.g., torn boots, excessive play).
  4. Replace any damaged components with OEM parts.
  5. Reinstall any covers and lower the vehicle.
