Roaring,rubbing sound from rear end
2014 ezgo rxv has lift all that. When rolling slow the cart makes a rubbing roaring sound at low speed it stops when speeding up and going at a nice pace. Maybe the bearing? Just changed all the gear oil few weeks back.

Re: Roaring,rubbing sound from rear end
Just a guess. Electric RXVs have limited slip. Did you include friction modifier with your oil change?

Re: Roaring,rubbing sound from rear end
one more guess---tire rub but that shouldn't go away with speed. All I got.

Re: Roaring,rubbing sound from rear end
Tire rubbing on the radius at the rear bumper? This one has already been trimmed.

Re: Roaring,rubbing sound from rear end
I'll check when I go back up seems this sound started after I got the new controller put in and almost like the brakes dragging or somethin. But the cart drives and acts fine just that rubbing sound.

Re: Roaring,rubbing sound from rear end
Can you determine where noise comes from? Front or rear of cart.
Some aftermarket tires with aggressive tread patterns may be noisier depending on speed. Noise change depending on load in cart or road surface? Bearing noise usually gets louder with speed. Are you sure noise came after new controller or just never noticed till after install. Were any other mods done at same time of controller upgrade. If brakes were dragging you should feel it along with dragging batteries down along with excessive heat from brakes. Just few things to check. |

Re: Roaring,rubbing sound from rear end
Just a thought. Maybe you have a rock or something inside a drum?

Re: Roaring,rubbing sound from rear end
There are no brake drums or wheel brakes on an RXV, regen braking only. The electrical motor brake unit is a parking brake only. The aftermarket brake kit available is front disc brakes only.
