I know someone that has a good deal on a rear 44, but I might need it. I hope to figure out if my problem is in the rear diff tonight or tomorrow night. If I don't need the axle I will pass the information on to you.
I also have a rear 44 that I was keeping as a "spare", but it would need to be completely rebuilt. So if there is no problem with my axle, or I can get that other d44 to replace mine I might be willing to sell my spare 44.
