Well I guess I shot myself in the foot with this one.
I replaced all the ball studs and ball cups with jConcepts cups and TC6 studs. Today while practicing, I pulled a ball stud out of the rear hub, and 10 minutes later broke the rear camber mount and ripped out the ball stud. So now I have to replace the transmission case.
It appears the Durango ball cups as soft and flexible as they are, absorb some of the impact and prevent breakage. Doh.
