Re: cost of Dana 44 ???
Dude thats a Rip Off
I got my whole housing, knuckles, etc. for $100.
Yes any good junk yard should let you pick apart the axles as needed, infact here in the Seattle area we have a yard called "Pull Apart" and thats exactly how it works you go in and pull what you want /need.
If you haven't gone to a yard I'd suggest going.
The flat top knuckles are probabally going to cost you a litle extra since we Jeepers covet them, but that doesn't mean the daels aren't out there, just keep looking!
