Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on the suspension.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire.
Adjust tire pressure according to the manufacturer's specifications (usually found in the owner's manual or on the driver’s side door jamb).

3. Wheel Alignment

Tools Required: Alignment machine, torque wrench.
Attach the vehicle to the alignment machine and follow the manufacturer’s instructions to check the alignment settings.
Adjust the camber, caster, and toe settings as needed to bring them back to specifications (refer to the Tesla service manual for exact specifications).

4. Suspension Inspection and Repair

Tools Required: Socket set, wrench set, jack, and jack stands.
Raise the vehicle and secure it with jack stands.
Inspect all suspension components for wear or damage, including:
- Control arms and bushings
- Struts and shock absorbers
- Tie rod ends
Replace any worn components with OEM parts as necessary.
Reassemble and torque all fasteners to manufacturer specifications.

5. Tire Rotation and Replacement (if necessary)

Rotate tires according to Tesla’s recommended schedule (usually every 6,250 miles or as needed based on wear).
If tires are excessively worn or damaged, replace them with new, high-quality tires that match the specifications for the vehicle.
