Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, wheel chocks.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues during repair.

2. Remove Wheel

Loosen lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to gain access to the suspension components.

3. Remove Old Shocks

Tools Required: Wrench set, socket set.
Locate the shock absorber mounting bolts at the top and bottom.
Use a socket to remove the bolts and detach the shock from the vehicle.
Inspect the shock mounting points for wear.

4. Install New Shocks

Parts Required: New shock absorbers (specific to Tesla Model S).
Position the new shock in place and secure it with the mounting bolts.
Torque the bolts to the manufacturer's specifications (usually around 30-40 ft-lbs, refer to service manual for exact value).

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Torque lug nuts to the manufacturer's specification (typically 80-100 ft-lbs for Model S).

6. Final Checks

Reconnect the 12V battery.
Perform a visual inspection of the suspension to ensure all components are secure.
