Moog ball joint #'s ?
 

Yes, I have searched. In fact, I have it memorized that the moog lowers for my 2004 4x4 is part number k8695t. I went to order some from rockauto and they are saying the part is k80771, they don't even have the other one listed. I went on another car parts site, and they said both will fit my truck. Kinda confused, whats the difference? Is one oversized or hd or something? Will either part work/fit fine?

Both will fit, but I'd go with the K80771. It is Moog's "Problem Solver" ball joint.

Thanks guys, helps alot. So if I'm understanding this right, both parts fit a torsion bar suspension. But the k80771 is the problem solver, which means its slightly oversized to fit tighter in a stretched LCA hole. Now I wonder if mine has problems that need solving.....
