well I work underground so the trucks arnt that big, but everything is done with overrhead cranes, rattleguns, pnumatic/hydraulic jacks. There inst much lifting involved thankfully, but it is still a coupla days to pull out a tranny.

The touble with the pootrol box, is that the box doesent sit flat. The transfer box sits slightly lower then the main box, and the weight is not evenly spread, so you cant just put the box in the middle of the jack and lift.

still like I said never again
