That sucks dude! I frikkin hate shops like the one you wrote about, I know how you feel big time.

If the rear is an Eaton it may be easier to just swap the whole axle with another from a salvage yard, get the truck back on the road and get it home again. From there you can repair the rig at home, or get you more time to find a good shop to then drive to.

Just my first thought if I were in your shoes.
