The more resistance you put on the ring gear will make the ACTUAL drive points on the gear show up better. I use a 1 foot breaker bar on the pinion and the pry bar on the ring gear to make drag. Just make sure that the backlash is at .010-.012 because its a used gear and is broke in. You will get it
Ill add more tonight and get a picture, and put some more drag on it.
