First off, when possible, always tow from the rear, either from rear tow hook or tow hitch. Backing up to get someone out may result in major issues with the front differential.
Secondly, i think that you guys are discounting too much on the front hooks. Are they not bolted/welded to the frame?? I can't remember clearly but my '02 4runner (3rd gen) tow hook was not much different than the 4th gen. So, i don't think that Toyota has changed the tow hook(s) from 3rd gen to 4th gen.
RonM, is your tow hook different than 4th gen???
Falls, i doubt that your American counterparts have any stronger hooks in front.
