When I went to a total lift of 6.5" I bought and installed the RE Extreme Duty front track bar. Installation and adjustment was a snap. But the joint at the frame attachment has play! I've narrowed it down to the bolt. It seems the bolt diameter is a thousandth or two smaller that the inside of the joint. Has anyone else had this problem? Is there a grade 8 bolt with a lagger shank diameter ou there?
