Steering All Over the Place at 55mph+

The procedure 72bluNblu outlined in post #60 is exactly the way I did mine. (Except I used a length of 1/2" threaded rod) I like the idea of just rotating the UCA around so that you don't have to separate the upper ball joint. That could save a lot of time if you've never done it. There's most likely nobody in that shop who has done an old Mopar before and they could actually do sone damage. You'll do the job correctly and save money.

An impact would make it go pretty quickly but it might be good to gave a buddy come over to give you a hand and provide moral support if you're using hand tools.

I would suggest getting all the parts together and go to it. Make absolutely sure you understand the orientation of the offsets and mark the UCA with a Sharpie showing which way the arrows need to point while it's still assembled on the car. Your goal is to move the UBJ rearward.

The slop in the idler isn't terrible but now would be a good time to change it before you get it aligned again.
