You should look somewhere else for what's clicking.

After the whole Rockstomper swaybar disconnect fiasco, it was obvious that heims are bad for use in vibration environments. But the SAW's are ALWAYS putting a massive force in the same direction on the heim joint, even while on a bumpy road. So I think this is one application of a heim that's great. I never hear my SAW's clicking.

I've previously gotten clicking from the top nut on the rear shocks, the nuts on the rear swaybar disconnects even if stock, the rear lower control arm bolts (I replaced them with very slightly larger bolts), and other places. Nuke front disconnects still have one heim joint, although no one complains about them.
