I don't have a problem with the auto hubs locking, it's just that they won't unlock right. I took the hubs off and taking them apart at least to the diaphram they are ok, but from the diaphram out to the **** it seems that when you lock manually it is ok but when unlocking, the diaphram and the piece between the **** doesn't want to go back in except when forcing by hand. Question I have, does anybody know how to get the **** or the diaphram out so as to clean out the manual part of the hub without breaking anything. I'm thinking that there is dirt or crud inside that part that won't let it work right. My fingers hurt!! Thanks Rob PS this is on a 2001 F-250
