what i did is took the whole trailing arm off. then i put it in the shop and welded a nut to the threads. then i took a hack saw and starter cutting the lca at the spot where it touches the trailing arm. then i heated the threaded hole for the bolt thread then slowly turned it out. if you cant get it this way then just take a hacksaw and cut the lca out but dont cut the lcs. just the bushing. you might have to do it on both sides. good luck and take it slow.
