Solution

1. Preparation

Tools Required: Jack, jack stands, tire iron, torque wrench, inspection mirror, flashlight.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection

Sub-steps:
- Remove the wheel covers, if applicable.
- Inspect each tire for signs of damage, such as bubbles, cuts, or uneven wear.
- Check tire pressure and adjust as necessary to manufacturer specifications.

3. Suspension Inspection

Sub-steps:
- Jack up the vehicle and secure it with jack stands.
- Visually inspect suspension components, including control arms, struts, and stabilizer links, for any signs of wear, cracks, or looseness.
- Shake and wiggle the components to check for excessive play.

4. Re-torque Wheel Lug Nuts

Sub-steps:
- Using a torque wrench, re-torque the wheel lug nuts to the manufacturer's specifications (typically around 100-110 ft-lbs for Tesla).
- Ensure that the lug nuts are tightened in a star pattern to avoid warping the brake rotor.

5. Address Any Identified Issues

Sub-steps:
- Replace any damaged tires or suspension components as needed.
- If the popping noise persists after addressing identified issues, further diagnosis of the drivetrain may be required, potentially requiring a professional assessment.
