Don't really need a case spreader to get the carrier out. A good pry bar and a buddy works just fine. When I did it one guy pried on the carrier one guy kept the whole thing from just hitting the dirt. Then a good plastic dead-blow hammer to pound it most of the way back in before tightening the bearing caps. Works just fine. Definitely get the seal install tools, if I did it again I'd get 'em, it was a bit of a pain without the install tools.
