Will the cart roll, showing the brakes are not locked?
If you raise the rear of the cart with both wheels of the ground, and turn one manually, does the other wheel turn in opposite direction? It should if axles and differential are ok.
Have you jacked it up to check the axles?
Noise is at controller and not drive motor? Drive motor coupler not stripped and motor is running, but not driving transmission?
Call it what you want, but Ezgo has a coupler between the drive motor and the transaxle.

What is year model and controller number? A1 and A2 are the armature wires, and the B1 and B2 are the field wires .
If the controller is powering up, problem is usually at the drive motor, and drive motor coupler is suspect!
Drive motor coupler is on the drive end of the drive motor!
Last image is the coupler.
It is a mechanical coupler that splines to the transaxle, it fails when it strips out the spline on motor or transaxle end.
With the controller making noise, as it powers up, I'm thinking that it may be motor.
OK< here is an Ezgo site with basic trouble shooting and it has drive motor test too, just scroll down the opening page past the manuals until you find the troubleshooting section.
I see question is still open, did you find problem?
