⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the high-voltage battery before working on electric components.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Whirring noise when the vehicle is in motion
•Noise is more pronounced during acceleration
•Possible vibrations felt through the chassis
•Increased cabin noise level
•No warning lights on the dashboard

Diagnostic Steps

1
Check for any visible damage or loose components in the wheel wells and around the drivetrain.

Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, OBD-II scanner, multimeter.
Ensure vehicle is parked on a level surface and set the parking brake.

2. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel by loosening the lug nuts with a socket set.
3. Inspect the wheel bearings for play or noise by spinning the hub.
4. If bearings are worn, proceed to replace them:
  - Remove the brake caliper and rotor.
  - Use a bearing puller to remove the old bearings.
  - Install new bearings, ensuring they are properly seated.
5. Reassemble all components in reverse order.

3. Inspect and Service Electric Motor (if necessary)

Sub-steps:
1. Access the electric motor by removing the motor cover.
2. Use a multimeter to check the motor windings for continuity and signs of shorts.
3. If the motor is faulty, consult a service manual for replacement procedures.
4. Ensure all connections are tight and free from corrosion.
