Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the high-voltage battery before working on the electrical systems.
•Ensure the vehicle is securely supported on jack stands before working underneath it.

Symptoms

•Grinding noise while driving, particularly during acceleration or deceleration
•Increased vibration felt through the steering wheel or floorboard
•Unusual sounds when turning or cornering
•Potential loss of power or abnormal acceleration response
•Warning lights illuminated on the dashboard (e.g., brake warning light)

Diagnostic Steps

1
Inspect the brake components for wear or damage, including pads, rotors, and calipers.
2
Check the drivetrain components, including the motor and gearbox, for signs of wear or damage.
3
Examine the suspension system, including bushings and joints, for any signs of deterioration.
4
Scan the vehicle's onboard diagnostics using an OBD-II scanner for any error codes related to the drivetrain or brakes.
5
Test drive the vehicle to replicate the noise and observe under different conditions (accelerating, braking, turning).

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Jack and jack stands

Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and set to 'Park.'
Disconnect the high-voltage battery system as per Tesla's safety guidelines.
Gather tools: jack and jack stands, socket set, torque wrench, and brake cleaner.

2. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel on the side where the grinding noise is most prominent using a socket set.
2. Inspect the brake pads for thickness; if less than 3mm, replace them.
3. Check the brake rotors for scoring or warping. Replace if necessary.
4. Clean the calipers and rotor surfaces with brake cleaner before reassembly.
5. Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 100-120 ft-lbs).

3. Drivetrain Examination

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Visually inspect the electric motor and gearbox for leaks or unusual wear.
3. Test the motor mounts for any signs of failure or excessive play.
4. If wear is found, consult with Tesla service for appropriate repairs or replacements.

4. Suspension Check

Sub-steps:
1. Inspect all suspension components, including tie rods, control arms, and bushings.
2. Check for any loose or damaged parts that could be causing noise during driving.
3. Tighten any loose bolts to manufacturer specifications.
4. Replace any worn-out or damaged suspension components as necessary.
