George, I'm surprised that Ron Siple didn't insist you use teflon lined rod ends because that's all he uses. If you told him you were using non-teflon lined rod ends, he'd tell you to switch to teflon lined immediately. They would eliminate all of that road noise transmission and harshness you're encountering. Also, modifying your lower control arms to use spherical bearings is much easier than modifying them to use rod ends. I'm pretty sure Siple's own Pantera is set-up that way.
