I've got the same issue on my 4Runner as well. I've got the Shrockworks bumper also and my noise is the body actually rubbing on my bumper when going over bumps due to normal body flex. The earlier versions of the install instructions had you drill holes when mounting the bumper to the brackets for a final alignment. Even with mine, as level as I could get it on install, is still less than a 1/2" from the panels under the headlights and fenderwells. Not sure what I'm going to do short of ordering a new set of mounting brackets and trying again.
That should be more of a clunk noise I would imagine than a squeaking noise... But I think I have a little less than 1/2" gap on my ShrockWorks currently and only when I am off-roading/flexing the truck and/or big bumps does it compress enough to whack the bumper (at least as far as I hear.)
Are you sure your body mounts are in good condition? If the mounts are starting to wear/tear they may let the body move too much on the frame, can you post pictures of your gap?
Post Note-
Aside from the smaller occasional squeaks that come from an aging vehicle I am happy to report that my Radflos have not been squeaking like before!
