Solution

1. Preparation

Gather necessary tools including an alignment rack or wheel alignment tool, torque wrench, and a socket set.
Ensure the vehicle is on a level surface and the tires are properly inflated to the manufacturer’s specifications.

2. Adjust Toe Settings

Sub-steps:
1. Loosen the lock nuts on the tie rods.
2. Adjust the tie rod ends to achieve the correct toe specifications (typically around 0° to 0.1° for the Model S).
3. Re-tighten the lock nuts to the specified torque, usually around 30 ft-lbs.
Tools Required: Torque wrench, socket set

3. Adjust Camber Settings

Sub-steps:
1. Loosen the upper control arm bolts.
2. Adjust the camber angle to the manufacturer's specification (typically around -0.5° to -1.0°).
3. Re-tighten the bolts to the specified torque, usually around 75 ft-lbs.
Tools Required: Torque wrench, socket set

4. Adjust Caster Settings (if applicable)

Sub-steps:
1. If the caster is adjustable, locate the adjustment points on the lower control arm.
2. Adjust the caster angle to the manufacturer's specification (typically around +7.5° to +8.5°).
3. Re-tighten all bolts to the specified torque, usually around 75 ft-lbs.
Tools Required: Torque wrench, socket set

5. Final Check and Test Drive

Sub-steps:
1. Double-check all alignment measurements after adjustments.
2. Perform a test drive to verify that the vehicle tracks straight and the steering wheel is centered.
3. Recheck tire pressures after the test drive to ensure they are still at the correct levels.
Tools Required: Alignment rack or wheel alignment tool
