Inspect tire pressure on all tires to ensure they are at recommended levels.
2
Visually examine the tires for any signs of damage or irregular wear patterns.
3
Check for proper wheel alignment using a wheel alignment machine.
4
Inspect suspension components (struts, shocks, bushings) for wear or damage.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all four tires.
- Ensure each tire is inflated to the manufacturer's recommended PSI (found on the driver's side door jamb).
- Inflate or deflate tires as necessary to achieve proper pressure.

3. Perform Wheel Alignment

Use a wheel alignment machine to check the alignment settings.
Adjust the camber, toe, and caster angles according to the manufacturer specifications.
- Typical alignment specifications for the Model 3 are:
  - Camber: -1.0 to -0.5 degrees
  - Toe: 0.0 to 0.1 degrees
  - Caster: 5.5 to 6.5 degrees
Lock down all adjustments and ensure all settings are within specifications.

4. Inspect and Replace Suspension Components (if necessary)

Visually inspect suspension components for any signs of wear or damage.
If any components are found to be faulty, replace them as follows:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Remove bolts securing any worn components (e.g., struts, control arms).
4. Install new components and torque to manufacturer specifications.
Reinstall the wheel and lower the vehicle.

5. Rotate Tires

Rotate the tires based on the manufacturer's recommended pattern (typically front to back or crisscross).
Recheck tire pressures after rotation.
