Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery to prevent any electrical issues during the repair.

2. Tire Inspection

Remove the hubcaps or wheel covers if applicable.
Check each tire for signs of wear, bulges, or foreign objects lodged in the tread.
Rotate or replace tires as necessary, ensuring proper inflation levels.

3. Wheel Bearing Inspection

Raise the vehicle using a jack and secure it with jack stands.
Grasp each wheel at the 12 and 6 o'clock positions and check for excessive play.
If play is detected, remove the wheel and replace the wheel bearing using a bearing press.

4. Drive Unit Inspection

Remove the underbody panels to access the drive unit.
Inspect for any loose connectors or visible damage to the motor assembly.
Tighten any loose bolts to manufacturer specifications.

5. Electric Motor Testing

Reconnect the 12V battery.
Start the vehicle and listen for any unusual sounds coming from the motor during low-speed operation.
If noise persists, further disassembly may be required to inspect internal components.

6. Brake Component Inspection

Check brake pads and rotors for excessive wear or damage.
Ensure brake calipers are functioning correctly and not sticking.
Replace any worn components as necessary.
