I picked this unit up at a salvage yard. Took it to my shop where I removed as much of the exterior rust as I could without resorting to blasting it. Two nice coats of gloss black Rustoleum. Completely drained and new fluid plus posi. additive were poured in. I went to replace the yoke /shaft seal and over torqued the nut.
Now it needs a new crush washer.
I am not well educated in this procedure so I installed another rear, this time an open 2:73 unit.
Hate to cut up the posi. for scrap.
Asking $85 for the rear (I paid $175 for it plus new fluids brought the price up to about $200.)
Pick up at my shop just minutes north of Philly, PA.
