Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, socket set, pry bar, and safety glasses.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it on jack stands.
Verify stability before working underneath the vehicle.

3. Remove Components for Inspection

Sub-steps:
- Remove the wheel on the side where the noise originates using a socket set.
- Carefully detach any protective covers or shields if necessary.

4. Inspect and Replace Worn Parts

Sub-steps:
- Examine the bushings, control arms, struts, and shock absorbers for signs of wear.
- If any components are damaged or worn, replace them with OEM parts.
- For bushings, use a pry bar to remove old bushings and install new ones using a bushing press or appropriate tools.

5. Reassemble and Torque Components

Sub-steps:
- Reattach the wheel and ensure all lug nuts are tightened to the manufacturer’s specifications (typically around 100-110 ft-lbs for Tesla Model 3).
- If struts were replaced, torque the top mount bolts to the specified torque (check the service manual for specifics).

6. Lower the Vehicle

Carefully remove jack stands and lower the vehicle back to the ground.
