My motor is making a high pitched noise, and it's not the normal noise from an esc

[jarofletesberkowitz]

I just installed a new motor and ESC in mt scx10ii, I installed a 27t brushed axial motor and hobbywing brushed crawler ESC. I am hearing a noise that sounds like the gear mesh and i can't figure it out, I tried adjusting the mesh but it just keeps the same constant loud grinding/squeaking noise. And when I put the body on it amplifies it more, any idea what the problem might be, maybe a bent motor plate? not sure
Thanks for the help, I'll try to get a video up as soon as I can

Check for a dry motor bushing... dry driveshaft joints... bad bearings...ect...

Is your mesh between the pinion and spur to tight? It needs to have a bit of play. Is your pinion/spur damaged or worn out. Did you check all the teeth of the pinion/spur for a grain of sand stuck in the teeth.

Why did you change the motor/esc? Did something burn up? Maybe there is an issue in the trans? Pull the motor and check for anything binding in the drivetrain

Just brainstorming here

I have checked the motor by itself, it's fine, I have checked the gears and they are fine too, and the mesh i keep adjusting it to get it perfect and just keeps doing it

Looks like you need to take a video so we can see and hear it
