Squeaky Motor

I think my motor is haunted?

What could be the problem? I did a separate test by disengaging the brakes still, there is a squeaky sound. Also, a noticeable drag is observed. Like an "engine brake" feel. It must be the motor.

My bet is your brake is dragging a little.

I'm not skilled enough if the electronic explanation, but sounds like something to do with the controller and the electronics. The only things that touch in a motor are the bearings and the nylon gears. That sounds like neither of those.

That's turning by hand, forward. Looks like a geared motor, so it should freewheel. Tire's not rubbing, of course? Got a shoelace caught in the gears? Take off the wheel and squirt some WD40 down the axle?

I've read some hubs have rubber seals to protect from water and dirt. Maybe I was cleaning too meticulously that it rubs off the lubrication down there?

I did a separate test where I removed the brakes. Still the same.
My guess is the rubber seal.

My bet is your brake is dragging a little.

I've read about that on the front, but not the rear. That sounds like it might be worth a shot.
