I have a nifty tool to remove the shafts from the lower control arm, but then what? My replacement bushings consist of a rubber bushing sandwiched between inner and outer metal sleeves. The problem is there is no way to get the old inner sleeve off the shaft, and no way to press the old outer sleeve out of the pivot assembly. Plus, I can't seem to disassemble the new bushing. Heck, all I need is the new rubber jobby. but I can't get it out. What am I missing?
