Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Tire Inspection and Pressure Adjustment

Remove the valve caps from each tire.
Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires as necessary to match the recommended pressure found on the driver's side door jamb.

3. Wheel Balancing

Position the vehicle on a wheel balancing machine.
Remove the wheels from the vehicle using a socket set.
Place the wheels on the balancing machine and follow the manufacturer's instructions to balance them.
Reinstall the balanced wheels onto the vehicle, ensuring proper torque (typically 100-120 ft-lbs for Tesla lug nuts).

4. Wheel Alignment

Use a laser alignment tool to check the alignment specifications.
Adjust the alignment settings as necessary to meet factory specifications.
Verify that the steering wheel is centered after alignment adjustments.

5. Drivetrain Inspection

Lift the vehicle and safely secure it on jack stands.
Inspect the driveshaft for any signs of wear, such as excessive play or damage.
Check the CV joints for signs of cracking or leaking grease.
Replace any damaged components as needed.
