Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the tires are cold for accurate pressure readings.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure each tire's pressure.
2. Inflate or deflate tires to the recommended pressure (typically 42 psi for Model S).
Tools Required: Tire pressure gauge, air compressor or tire inflator.

3. Wheel Alignment

Sub-steps:
1. Set the vehicle on a wheel alignment rack.
2. Adjust camber, caster, and toe angles to meet manufacturer's specifications (front: 0.10° ± 0.25°, rear: 0.20° ± 0.25°).
3. Tighten all adjustment bolts to manufacturer torque specifications (typically around 50-70 ft-lbs).
Tools Required: Wheel alignment rack, torque wrench.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect control arms, bushings, and struts for wear or damage.
2. Replace any worn components using OEM or high-quality aftermarket parts.
3. Ensure all bolts are torqued to specification (refer to service manual for torque values).
Tools Required: Socket set, torque wrench, replacement parts.

5. Tire Replacement (if necessary)

Sub-steps:
1. Remove old tires using a tire machine.
2. Install new tires ensuring they are mounted in the correct direction.
3. Balance tires using a wheel balancer.
Tools Required: Tire machine, wheel balancer.
