\r\n \r\n Depends on the motor, bearings are going to go first, but can be replaced, unless the case is acting as a bushing for the drive shaft. If you can take it apart and check the windings for dirt, burns, gaps, anything obviously wrong. I guess it just depends on the kind of motor though. Brushed, brushless, inrunner outrunner...\r\n
