I'm guessing the clip that you are talking about is in the middle of the locking hub, the other hub that it hooks to might be sticking out too much maybe the bearing races are not seated, try torqueing the 2" nut (just one for now) to 150 lbs or so to make sure that they are seated then take them back to 57 lbs. see how that does.p.s. oh ya the spring faces inward, gets grease on it, LOL.
