Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and parts.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if equipped.
2. Loosen the lug nuts using a socket wrench but do not remove them completely.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Remove the lug nuts and take off the wheel.
5. Inspect the tire for bulges, uneven wear, or other damage.
6. If the tire is damaged, replace it with a new one, ensuring it matches the specifications of the original equipment.

3. Wheel Lug Nut Torque

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque value (typically around 129 lb-ft for Tesla).
3. Double-check the torque on all lug nuts.

4. Inspection of Suspension Components

Sub-steps:
1. Visually inspect all suspension components for wear or damage.
2. Look for any loose bolts or bushings.
3. Replace any damaged components with OEM parts as necessary.

5. Driveshaft and Motor Mount Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or imbalance.
2. Check the motor mounts for any signs of wear or separation.
3. If damaged, replace the driveshaft or motor mounts accordingly.
