Ok, so I am trying to put in this Aussie in my 30 and keep running into problem after problem, not with the Aussie so much but with everything else. I am putting in new bearings and seals while I have it apart and the outer pinion bearing they say fits it is too small. When I cross referenced the number it is a pinion bearing out of a Dana 44 rear axle. They don't even have the dana 30 as having this bearing in it. Does anyone know what in the world is going on....strange. I guess I am going to replace it with the one from the dana 44 that matches, but it is harder to find too. Set me back yet another day on this half a day project.
