my Tesla Model 3 has a persistent grinding noise while driving, what's the cause?

Solution

1. Preparation

• Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and secured with wheel chocks.
• Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, inspection mirror, flashlight.

2. Brake Inspection

• Sub-step 1: Remove the wheel by loosening the lug nuts and lifting the vehicle with a jack.
• Sub-step 2: Inspect the brake pads for thickness; replace if they are below 3mm.
• Sub-step 3: Check the brake rotor for grooves or scoring; if damaged, replace the rotor.
• Sub-step 4: Reassemble the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 100 ft-lbs).

3. Wheel Bearing Replacement (if necessary)

• Sub-step 1: Remove the wheel and brake components to access the wheel hub.
• Sub-step 2: Use a bearing puller to remove the old wheel bearing.
• Sub-step 3: Install the new bearing and ensure it is properly sealed.
• Sub-step 4: Reassemble all components in reverse order and torque to specifications.

4. Drivetrain Component Check (if necessary)

• Sub-step 1: Inspect the driveshaft for any signs of wear or cracks.
• Sub-step 2: If damage is found, replace the driveshaft as per manufacturer guidelines.
• Sub-step 3: Check the differential fluid and replace it if contaminated.
