Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during inspection.

2. Inspect Drivetrain Components

Remove the rear wheel covers to access the drivetrain.
Check for loose bolts or damaged mounts on the motor and gearbox.
Tighten any loose bolts to the manufacturer’s torque specifications.

3. Inspect Wheel Bearings

Remove the rear wheels for better access.
Spin the wheel hubs by hand to check for any grinding noises indicating bad bearings.
Replace any worn or damaged wheel bearings if necessary.

4. Check Suspension Components

Inspect the suspension arms, bushings, and struts for any signs of damage.
Replace any worn bushings or components to eliminate noise during acceleration.

5. Reassemble and Test

Reinstall the rear wheels and wheel covers.
Reconnect the battery.
Perform a test drive to ensure the noise has been resolved.
