Backlash is term used to describe excessive clearances caused by worn bearings or ball screws and nuts. When the backlash becomes too great it can cause the servo to vibrate and shake. You can easily feel this by turning it by hand. Also you said the motor had heated up, check to see if the windings have not shorted.Quote:
