Messing around with this dana I got. I've got it all stripped down and am installing the pinion with the old shim packs for a starting point. There was no scribe mark on the new pinion. So I install it, with a new 1350 yoke, and it won't turn. Removed both shim packs for shits and grins, and same result. Put the old pinion with original bearing back in, same results.


Am I doing something wrong?
