Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is powered off before starting any work.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires as needed to match the recommended psi specified in the owner's manual.

3. Perform Wheel Alignment

Tools Required: Alignment machine, torque wrench
Position the vehicle on an alignment rack.
Adjust the alignment angles (camber, caster, toe) according to Tesla's specifications using the alignment machine.
Tighten all suspension bolts to the manufacturer's torque specifications.

4. Inspect and Replace Suspension Components (if necessary)

Visually check for worn or damaged parts in the suspension system.
If any components are found to be damaged, replace them with OEM parts.
Ensure proper installation and torque all bolts to specifications.

5. Rotate Tires

If tire wear is uneven, consider rotating the tires to promote even wear.
Follow the recommended tire rotation pattern for the Tesla Model S Plaid.
