I have Racing Dynamics front and rear sway bars. The back mounts on the trailing arms have wallowed out to the point that the links are quite loose and emits a very annoying rattle. Do I need to weld a fender washer on each side to restore the original hole location or is there something else to try? I can wiggle the sway bar links quite a bit by hand. I have H&R springs and adjustable Konis.
