Great info there CK. I was not aware of it. I know alot of things about vehicles, but never got alot into 4x4's until I wanted straight axle 4x4s. All my other 4x4's were wussy 4x4 IFS push a button, loaded, leather, seat heater, don't wanna get a scratch on it trucks, so I never did anything real fun in them. I have heard about the support bracket to get it regardless, that there are only 2 kinds of 4x4 SAS frames in GM, the ones that have cracked, and the ones that will crack if they haven't yet. So I have full intention of getting the support brackets for mine before they do crack.
Also, been hearing C4 talk about crossover steering. Does crossover steering fix this issue your talking about? It would be cool if you, and/or C4 could or would get together and do a crossover steering thread, especially if it corrects that articulation problem.
