I cant imagine the sb end links causing that loud of a rattle to where you would hear them while driving. then again I found a loose lug nut once on a back tire and heard the rattle from the washer.
if you think its the end links this is what i would do take off the sway bar and take a drive if you have the noise still then its not the end links. thats how i would try to find out since im no mechanic
Mine has done this ever since I got it and it drives me crazy. It feels like something in the steering column is loose and I've tried tightening all sorts of stuff and nothing seems to have helped it. It's really only noticeable when going over bumps or while off road, but its noticeable none the less.
