Replacing upper and lower ball joints on ford f250 4x4 ...

Customer Question

Replacing upper and lower ball joints on ford f250 4x4 year 1999. Have brake assembly off Hub off and trying to get axel out. Not sure how to get the seals out which I think is the reason I can not get the axel to slide out so I can remove the old ball joints and install the new ones. Also is there a place online that I might find an exploded view of differential?

Reply to Ms. Wrench's Post: Its is a super duty. I have figured out how and removed the axle. Is it nessesary to mark anything as far as tire alignment for installing the new ball joints if you plan on having it aligned once the new ball joints are installed? Next problem I might encounter is putting the new seals back on the drive axle shafts.
