Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Use wheel chocks to secure the vehicle.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor.
Check and adjust the tire pressure on all tires to match the recommended PSI found on the driver’s door jamb sticker.

3. Tire Inspection and Rotation

Tools Required: Jack, jack stands, lug wrench.
Lift the vehicle and remove the wheels.
Inspect each tire for signs of uneven wear or damage. If present, consider replacing affected tires.
Rotate tires if uneven wear is found to promote balanced wear across all tires.

4. Wheel Alignment

Tools Required: Alignment machine (if performing professional alignment).
If the visual alignment check shows discrepancies, take the vehicle to a professional alignment shop.
Follow the alignment specifications for the Model 3, ensuring camber, caster, and toe settings are within manufacturer specifications.

5. Suspension Inspection

Tools Required: Torque wrench, socket set.
Inspect all suspension components for wear or damage.
Replace any worn components such as control arms, bushings, or ball joints according to manufacturer specifications.
Use a torque wrench to ensure all fasteners are tightened to the specified torque values.
