So on my 04 F250 5.4 4x4 leaf springs. the left Front upper spring hanger bushing is shot and squeaking bad. I went to remove it and the exhaust pipe is in the way on one side and the body mount is in the way on the other side. Is there away to do this without dropping the exhaust? Once the bolt is out how do I get the old bushing out of the frame? I bought the Energy suspension front spring bushing kit.
