Solution

1. Preparation

Gather tools: alignment machine, tire pressure gauge, jack, jack stands, and a torque wrench.
Ensure the vehicle is on a level surface and the tires are at the correct pressure.

2. Tire Pressure Adjustment

Using a tire pressure gauge, check the pressure of each tire.
Inflate or deflate tires to match the recommended pressure listed on the driver's door jamb.
Recheck pressure after adjustments.

3. Tire Inspection

Remove the wheels using a jack and jack stands.
Examine the tread on each tire for signs of uneven wear.
Replace any tires that are excessively worn or damaged.

4. Suspension Inspection

Visually inspect suspension components including control arms, bushings, and tie rods for any signs of wear or damage.
Replace any components that show signs of wear.

5. Wheel Alignment

Set the vehicle on an alignment rack.
Adjust the alignment settings according to the manufacturer’s specifications for the Tesla Model S.
Ensure caster, camber, and toe angles are within the specified range.
Torque all suspension components to the manufacturer’s specifications after adjustments.

6. Test Drive
