Ok guys i am now in the process of installing the 4.56 in the Dana 30 high pinion. I took everthing apart have a few questions. (its setup much different the rear Chry 8.25. In front of the rear pinion bearing you have the race followed by some beveled washer. no other shims there. Then half way up the pinion you have a kind of step with a seriers of several shims. i am assuming these are to set preload. Then you have the front (yoke side) bearing race the front bearing another oil style flinger and the the seal. My question is i don't know where the shims are to set pinion depth. There were none under the rear pinion bearing either. Just another oil slinger. Are the shims to adjust the pinion depth the ones half way up the pinion gear? i don't think so because those looke like the ones neccessary to set preload. The other thing i am unsure about is how do i know how tight to make the pinion nut with a shim style (vs the crush sleeve). is the pinion nut essentially supposed to stop itself once the threads are finished. And at that point you should have your 12inch-lbs of resistance. Any help would be great. thanks
