tough as nails rear end ubolts

[chris71]

man, i was amazed at how much umph it took to get off my rearend ubolts when i swapped rears two weeks ago. i litearlly broke the head rigth off of a 2 foot breaker bar that i was using. i ended up using a 6.5 foot pipe on a foot long wrench (total from tip tip tip was 7 feet long) after wire brushing the u bolt threads and generous coats of pb blaster. these things were not that rusted either. i used the 7 footer to loosen them like 2 turns and then was able to man handle them the rest of the way off with another 2 footer breaker bar. the weird part is, after doing all this, i cleaned the threads, and was able to screw on the nuts by hand. for any guys out there doing this, its probably easier and less time consuming to just cut the ubolts and get new ones.
