So my steering rack bushings are shot. In my attempt to replace the old bushings, I'm stuck trying to remove the metal sleeves (got the inner rubber bushing out). I have tried cold chisel and air chisel together with PB blaster and even put a small hole in the old sleeve (see picture). The sleeve looks very beat up yet would not budge one bit. Any suggestions on what I'm doing wrong? I'm still on the bottom passenger side sleeve and have been at it for much of last night and this morning.
