Solution

1. Preparation

Tools Required: Jack, jack stands, mechanic's stethoscope, torque wrench, socket set, wheel chocks.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery for safety.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to lift the front of the vehicle and secure it with jack stands.
- Place wheel chocks behind the rear wheels for additional safety.
Remove Front Wheels:
- Using a socket set, remove the lug nuts and take off the front wheels.
Inspect Control Arms and Bushings:
- Check for cracks or excessive wear on control arms and bushings.
- If damaged, replace them with OEM parts.
Check Shock Absorbers:
- Inspect for leaks or damage.
- If necessary, replace with new shock absorbers.
Reassemble Components:
- Reinstall the wheels and hand-tighten the lug nuts, then lower the vehicle to the ground.
- Torque the lug nuts to the manufacturer's specifications (usually around 100-110 ft-lbs for Model 3).

3. Steering Components Inspection

Check Tie Rod Ends:
- Inspect for play or damage by grasping the tie rod and pulling it back and forth.
- If play is detected, replace the tie rod ends.
Inspect Steering Rack:
- Check for leaks around the steering rack and secure mounting bolts.
- Tighten any loose bolts as necessary.

4. Final Assembly and Testing

Reconnect the 12V battery.
Test drive the vehicle to ensure the noise has been resolved.
