Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised on jack stands.
Safety warning: Disconnect the 12V battery before working on electrical components.

2. Inspect and Replace Damaged Components

Inspect Shocks and Struts:
- Remove the wheel to access the suspension.
- Check for oil leaks on the shocks/struts. If leaking, proceed to replace.
Replacement Procedure:
- Remove the top mounting bolts of the shock/strut assembly.
- Remove the lower mounting bolts.
- Install the new shock/strut, tightening bolts to manufacturer torque specifications (typically around 30-40 ft-lbs, check specific model guidelines).

3. Alignment Check and Adjustment

Perform Wheel Alignment:
- After replacing suspension components, take the vehicle to a professional alignment shop.
- Adjust the camber, caster, and toe settings according to Tesla specifications.

4. Tire Replacement (if needed)

Inspect Tires for Wear:
- Check for uneven wear patterns; if present, replace affected tires.
Installation:
- Mount new tires and ensure they are balanced properly.
