So I am running a hp d44 from a 79 ford f250 under my xj and the other day I was installing new balljoints and the upper balljoint would slip out of the steering knuckle. I have a heard a couple of different things that it could be. One is that the ears on the steering knuckle could be warped and a solution would be to just buy a new knuckle, second was that I might not have torqued the upper ball joint screw ( that little threaded insert that you install in the C knuckle before installing the upper ball joint) to the right amount, or three which I am dreding would be that the C knuckle has bent one way or another and when ever i tighten the lower one in and then tighten the upper, the upper starts to get pushed out. does anyone have any ideas on this and if it is the dreded #3 then how would I go along finding out which way to heat up and bend the C knuckle back to the correct spot. thanks for any help.
