Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a level surface and set to "Park."
Disconnect the vehicle from any charging source.

2. Inspect Rear Electric Motor

Remove any protective cover over the rear electric motor.
Check for any signs of wear or damage on the motor components.
If damage is found, proceed to replace the motor.

Locate the transmission fluid dipstick or access point.
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
If the fluid is low or dirty, drain the old fluid and replace it with the manufacturer-recommended fluid.

Raise the rear of the vehicle using a jack and secure it with jack stands.
Spin the rear wheels by hand to listen for noise or roughness.
If noise is present, disassemble the wheel hub and replace the bearings as necessary.
