Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, alignment equipment, and a wrench set.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires as necessary to match the recommended pressure listed on the driver’s door jamb.

3. Tire Inspection

Remove the front wheels using a wrench and jack stands.
Inspect the tread for signs of uneven wear or damage.
Replace any tires that are excessively worn or damaged.

4. Perform Wheel Alignment

Use alignment tools to check the toe, camber, and caster angles.
Adjust the alignment settings as per Tesla specifications:
- Toe: Ensure it is within 0.05 degrees of the specified range.
- Camber: Should be close to -1.5 degrees for optimal handling.
- Caster: Aim for +5.5 to +6.5 degrees.
Tighten all bolts to the specified torque settings provided in the service manual.

5. Reassemble and Test

Reinstall the wheels and lower the vehicle from the jack stands.
Take the vehicle for a test drive to confirm the pulling issue has been resolved.
