Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, jack, wheel chocks.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during the repair.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels to gain access to the shock absorber assembly.

3. Remove Old Shocks

Tools Required: Socket set, possibly a breaker bar.
Locate the upper and lower mounting bolts of the shock absorber.
Use the socket set to remove the bolts, ensuring to support the shock during removal to prevent it from falling.
Carefully detach the old shock from its mount.

4. Install New Shocks

Parts Required: New shock absorbers (ensure they are compatible with Tesla Model S).
Align the new shock absorber with the mounting points.
Insert the upper and lower bolts but do not fully tighten at this stage to allow for adjustment.
Once aligned, use the torque wrench to tighten the bolts to the manufacturer’s specifications (typically around 40-50 ft-lbs, verify with service manual).

5. Reassemble and Test

Reattach the wheels and lower the vehicle back to the ground.
Reconnect the battery.
Test the suspension by performing a bounce test again to ensure proper function.
