I have a 2002 F-250 with 235,000 miles and was trying to remove the tow hook bolts (3) per hook. I sprayed them up with PB Blaster and first used an impact wrench. First mistake. Pretty sure i snapped the bolt cause it just spins and the top threads don't. The nuts are tack welded on. So to test a theory, I moved to the right side to attempt to remove one bolt. This time I heated the be-jesus out of it, sprayed the "get 'em off juice", and first used a ratchet on it and sure enough it loosened up. So, guessing that method works well for 21 year old bolts. Now, how would I get out the bolt that is spinning on the left side tow hook? Space is tight as you all know. Any ideas?
I relocated mine a few years ago, so I can't remember the stock configuration -- are the welded nuts on the back the only threaded portion that the bolt utilizes? If so, you should be able to remove the other bolts and the one you broke would just fall out. Once you got the hook off I'd imagine you would be able to get on the seized portion of the broken bolt with a stud extraction tool, vice grips, pipewrench, whatever you've got to try and unthread it.
So the best I have is mapp gas. I'm thinking to heat the nut up until it gets beet red and knock it loose with a cold chisel. The bolt head definitely spins but upper remnants of the top bolt don't. It's what I get for experimenting.
