Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Use the jack to lift the rear of the Tesla Model S.
Secure the vehicle with jack stands for safety.

3. Inspect Suspension Components

Remove the wheel to access the suspension components.
Visually check the shock absorbers for leaks or damage.
Inspect control arms and bushings for cracks or excessive wear.

4. Tighten Suspension Fasteners

Using the socket set, check the torque on all suspension fasteners according to Tesla specifications (refer to the service manual for exact torque values).
Tighten any loose bolts or nuts.

5. Replace Worn Components

If any components are found defective, replace them. For example:
- Remove the old shock absorber by unbolting it from the top and bottom mounts.
- Install the new shock absorber, ensuring proper alignment.
- Torque the bolts to the manufacturer's specifications.

6. Reinstall Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the specified value (typically around 100 ft-lbs).
