Clunking during slow turn.
My car has just over 150 miles on it now. Still kinda shaking it down. When I pulled it in my shop I felt a clunk that was in the rear area. I don't know why but my first thought was the front spring mounts. I have the factory 4 leaf springs with bolt on frame connectors. Compition engineering I think. I checked the three mounting bolts on the spring cups. They were not loose , but were not tight either if that makes any sense. So I took the drive shaft loose and the shocks too. Lowered the rear down in the front. I really didn't pay much attention to the speed nuts when I put them in because they were new. I popped One out and looked at it. It was just a pressed cone shaped nut. My feeling is that they stretched. I looked through my stash and found a original. It has an actual nut welded on it. So I ground down the cone on the reproduction ones and welded a grade 8 nut on it. I simply ran a bolt up from the bottom to hold the nut in place. Took 30 minutes to do all 6. Just something to keep in mind for y all high power builders. Pictures of cone shape verses nut original style.
