to check your bearing open the the door.grip the top of the drum then lift it with an up and down motion.the drum will move in any case while attatched to the shock absorbers..But what your looking for is a pretty slack movement,another way of finding out if your bearing is shot,is to remove the back panel and with the door open hold the top of the drum with one hand then hold the fly wheel at the back,whilst lifting the drum at the front,if theres any play on the fly wheel.then your bearing is shot,also a trickle of black oil coming from the flywheel side bearing is a tell tale sign...
