I'm in the middle of installing UPR upper control arms and UPR upper torque box reinforcements. I got both arms out, 1 torque box reinforcement in and done. I started putting in one of the arms but the rear end side bushing/shell are holding me back. How do I get it out? I got the bushing out easily, but the shell is stuck. I was banging it with a hammer and it doesn't seem to be budging. My dad gave me a lump hammer so i'll try that maybe tomorrow. Anyone have any tips BESIDES buying the MM tool?
