Weird tail motor noise

[robot432]

During one of my flights, one of the esc wires came loose so I resoldered all of the wires(to make sure they are all good solder joints) and it runs fine on idle, but with throttle, the motor makes a bad grinding noise after a second or two and it heats up.

Any help would be greatly appreciated
