Has anyone else had an issue with the 7/8"-1.25" adjuster bung going into the Upper IRS control arm. One went in like butter (by hand) while the other took 2 hours of sweating, pushing, a bench vise and a few choice words. I know it wasn't cross threaded, but I did notice the threads were getting flattened. I worry about this because I think it will hinder the ability to adjust it for alignment. Do I call FFR for a replacement or just live with it? Any advice is appreciated.
