Ahem... ATTENTION DOUCHEBAG !!!
Did I not talk to you about this very frickin' subject recently?
I ended up using a sawzall. Worked just fine, just be sure to bias the bushing side so you don't end up shaving the frame brackets. It is a miserable job but the only way I could get them out. I tried a torch and ended up spinning the sleeve inside the rubber cause I got it too hot. The impact didn't touch them and the air hammer did no good.
If you need a real man to take them out, call me direct. I will use my majestic hammer to pound them out, and I'm not talking about a hardware style hammer if you know what I mean. Speaking of the "hammer", tell your wife Hi for me.
Signed,
Stink stankety fruit saladishish slab of manhood.
