Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and pry bar.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands before working underneath.

3. Inspect Suspension Components

Shocks and Struts:
- Remove the wheel to access the shocks.
- Inspect for any visible leaks or damage.
- Check the upper and lower mounting points for tightness.
Sway Bar Links:
- Locate the sway bar links and inspect the bushings for wear.
- If damaged, remove the sway bar link bolts using the socket set and replace them.

4. Tighten Loose Components

Use a torque wrench to tighten all suspension-related bolts to the manufacturer’s specifications.
Refer to the service manual for torque values specific to the Model S.

5. Replace Worn Components

If shocks or sway bar links are found to be faulty, replace them with OEM or quality aftermarket parts.
Follow the removal and installation steps as per the vehicle service manual for precise instructions.

6. Reassemble and Lower Vehicle

Reinstall the wheels and tighten lug nuts to the recommended torque.
Remove jack stands and lower the vehicle to the ground.
