I'm not seeing how I can do what the Manual says to remove the differential. Should it just slide out one side above the frame member? The passenger side has slightly more room due to the absence of a protruding brake clip on the driver's side. The manual talks of sliding the unit in one direction, then tilting the unit and coming under one frame side, then lowing the other side to remove. I can't do that. Not enough room, and my muffler pipes were welded. I'd apparently need to cut the pipe, but if I did cut the pipe, I seriously cannot see how that provides more maneuvering ability. Any ideas?
