got them today at Napa, 12 bucks even for them. Tried the impact and a wrench before getting the grinder out, took them off pretty easy, I figured either they would come off, or maybe snap. Putting them on wasnt too bad, had to pry the pass side a bit to get the new stuff put in there, about a quarter inch. Made a noticable difference in driving, feels much better now. Thanks again guys for the replies.
and yes, one of the washers and bushings was pushed down over the center sleeve, so it was still there, just hiding ! lol
