One way to tell if there is side play- run the motor on the bench out of the vehicle and if it makes a HORRIBLE NOISE then the bearing is shot. Seriously, it will make a horrible noise because the shaft will start to orbit inside the area of play. If there is no side play then it will just sound REALLY cool!
