I always cut them off and replace them.The last set I bought were made in front of me in 5mins and cost $15.I don't think it's worth the fight to save the old ones.

I agree 100% with using an aceteleyene wrench to get the old stuff off. When I install them I put a good soating of antiseize on and when all done another coating of the stuff. When I pull them, I clean all the antiseize off and they look like new and very easy to inspect. Like I said I've only had to recycle em once when i swapped the rear end in the Blazer. Since then they never loosened and I did alot of pulling with her. I should also add that they were HD 5/8 U-Bolts, so that played a facter in their re-use as well.

I did mine on my 84 to find that one was cross threaded from GM (there really isn't a better hold than a good tight cross thread). Yes I put the same ones back on. Yes it lasted. I had no heat available and needed to drive to work the next day.

Not proud, but it worked and lasted.

I had that PB blaster soaked into a couple of caliper bolts for the goat and after 2 days even a 1/2" impact couldn't get them off. One shot of Marvel Mystery lube and 5 minutes later they came right off.

PB Blaster did all the work--the mystery oil did the final wetting.
