I think it is the sulphur - but not certainShock proof 90-140 I think went to ck and have none on shelf. By the way their primary oil is waaaay to thin IMHO. I use shock proof in primary and they really quite down! Belray second choice.. What are we looking for when someone claims Hypoid oils will attack bronze/brass bushings. (I know opening a can of worms)
Hypoid oil is completely unnecessary in an AMC box.
It has special additives to minimise wear from hypoid bevel, often helical, gear meshing. Hypiod gears are simply bevel gears where the axes don't intersect - common in many old differentials. It is done for practical space issues but creates extra sliding at the points of gear contact.
