AS some of you know I was going to try the Jag ball joints to give me more negetive caster (this was according to J.K. Jackson), well they dont work. Two reasons--the Jag ball joints tappered shaft does not fit right--and something that should have been more obvious to me is that the trunnion is preset to a specific angle (caster) and any induced change in the caster puts the trunnion in a bind. I didnt realize (stupid) this untill I had put the front end back together and found that the steering was too hard to turn. originally I had induced more negetive caster by adding more shims to the rear which pushes the bottom wishbone with trunnion forward--I wonder how much bind I had with that set up?--it was tough to turn at low speeds. The good thing is that its easy to change out the upper ball joints.--- I KNOW MANY OF YOU TRIED TO TELL ME NOT TO CHANGE TO THE JAG---YOU WERE RIGHT. For sale(cheap)Jag ball joints.
