From what I understand the rear axle is still good, wheel bearings are fine, what replacement parts would be needed???
When they say you blew out rearend, what needs to be replaced? on 1997 Toyota T100
THIS MEANS YOU NEED AN INSP OF ENTIRE REAREND, ITS A TARE DOWN AND INSP THING TO GET PROPER EST
Dissasemble and inspection of worn or damaged parts is the only way one would really know.
A lot of money. Just buy a used rear axle and be done with it. That will be cheaper than repairing it.
