Will be doing some rear suspension mods soon. From what I've read it appears that most of the critical fasteners in both the front and rear suspension (LCAs, UCA, panhard, swaybar, etc) are "one time use" or TTY-type, and should not be retightened or reused if removed. Although a PITA to have to do, seems to me to be relatively cheap insurance against potential catastrophic part failure. Or, are there certain "one time use" fasteners that are really ok to re-use? What say you...?
