how to fix Tesla Model Y Current (2020-present) when it makes a grinding noise

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the car is parked on a level surface and engage the parking brake.
• Disconnect the 12V battery for safety.

2. Inspect and Replace Brake Components

• Sub-steps:
  1. Remove the wheel by loosening the lug nuts with a socket set.
  2. Use a torque wrench to remove the caliper bolts and detach the brake caliper.
  3. Inspect the brake pads and rotors for wear; replace if thickness is below specifications (usually 3mm for pads).
  4. Clean the brake caliper and rotor surfaces with brake cleaner.
  5. Reinstall the new brake pads and caliper using the torque wrench to ensure bolts are tightened to manufacturer's specifications (usually around 25-35 ft-lbs).

3. Inspect and Repair Drivetrain Components

• Sub-steps:
  1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
  2. Inspect the drive shafts for any signs of damage or wear (cracks, tears).
  3. Check the differential fluid level and condition; replace if low or contaminated.
  4. Tighten any loose bolts on the drivetrain components to manufacturer specifications (consult service manual for torque values).
  5. Reassemble any removed components and lower the vehicle.
