[sweater914]

it's 22mm, just took them off a couple of days ago, the nut is a nylock type, surprisingly they weren't to hard to take off (the engine wasn't installed), be wary though, one of my trailing arms had a washer that seemed to be slightly undersized and took some real prying to get off, which screwed up the threads on the bolt/stud, the stupid thing is only the left one had the pain the butt washer
