It?s definitely salvageable at this point. I mean a new ring and pinion and a handful of bearings and the whole thing will be brand new.

I?d see what the brand new parts cost versus the cost of a used axle assembly and decide which way is the best bang for your buck.

If you haven?t dealt with this kind of repair before you may be better off letting someone with some experience do it. Nothing worse than brand new parts that weren?t installed correctly and are noisier than the worn out parts that they replaced.
