if you mean console bushes, then they arn't hard to do but you can't just do them on the driveway, i just did mine and replaced them for audi tt ones, i cut the old ones off after removing the whole bottom arm, then pressed the new ones on, as i didn't want to distort them by hammering ect. once you've got the old one off, make sure the hex shaped end of the bottom arm is clean of corrosion and greased up ready for the new one to go on too.
