Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure that the vehicle is stable before proceeding.

3. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Check for oil leaks or physical damage.
- If damaged, remove and replace with new shocks/struts.
Check Control Arms and Bushings:
- Look for cracks or excessive wear in bushings.
- If needed, remove the control arms and replace bushings or the entire arm.
Inspect Sway Bar Links:
- Check for looseness or wear on sway bar links.
- Replace if any signs of damage are found.

4. Tighten or Replace Hardware

Inspect all bolts and nuts in the suspension assembly for tightness.
Use a torque wrench to ensure components are tightened to manufacturer specifications (consult Tesla service manual for specific torque values).
Replace any stripped or damaged bolts.

5. Reassemble and Lower Vehicle

Reattach any components removed during inspection.
Ensure all tools are removed from under the vehicle.
Lower the vehicle back to the ground and remove jack stands.
