Car sat for about week after a drive around the farm where I lost a shock mounting screw. Got it put back together today and now the steering isn’t responding well. I’ve checked all the connections and took the linkage off and the servo is working fine, but the servo saver seems to be slipping or not engaging right. There doesn’t seem to be any visible damage to the servo saver. Does anyone know a way to test the servo saver? Also, before I took it apart, I did not take note of the angle that the arm so some help there would be appreciated as well!
