Just got through fixing an axle that went in on me. Opened the lock collar on the outer bearing and slid it out until the sprocket was lined up and tightened the collar again. Went around to the front to pull my bent axle off and try and straighten it and it had a locking collar on the inner bearing. The rear didn't. And I got to looking around and this was the only axle that does. My question is are they all supposed to have two lock rings in the bearings? One on the out side and one on the inner bearing in the middle of the tub???
