I have Energy Susp. in my stock upper and lower CA and lower I put a weld in plate when I had the 12 bolt rebuilt 10ish yrs ago, would those make a noticeable difference?
The Roto-Joints are smooth. Now that I have most of the bad movement gone from the welding it is noticably smoother. I think that once I get these new uppers installed it will make more of a difference. The other benefit is no binding at all.
