I used to have the tool but I let someone borrow it and well...thats the end of that one...Dont feel like spending $55 for a new socket...I am also worried about stripping the threads on the UCA...is there any trick to removing it through years of broken knuckles? Should I be soaking it with Liquid Wrench for a few days before I attempt the task? Should I heat it up with some Mapp Gas to break it loose? Should I whack it with a hammer? Should I give it some Red Bull and cross my fingers that it willfully surrenders on its own?
