Has anyone ever changed these ?? I bought an upper and lower control arm set and they didnt come with the bushings for the axle housing. How do you change them ?? Do you whack the old ones out with a hammer ?? They look rusted in there pretty good. Do the new ones need to be pressed in ?? I dont see the point of getting new control arms with nice urethane bushings and leaving the crappy rubber bushings in the rear end.

I used the poly bushings, mine were split in serveral spots.
