setting the lash in 8 3/4

I think I can get my hands on a magnetic dial indicator. So you're saying tighten one adjuster to push the ring gear to zero lash on the pinion. Then tighten the other to push ring gear away .006-.010 from the pinion, while not moving the the first adjuster at all. correct?

Tighten them until you have about .001 clearance, or just until you can tell there is the smallest of backlash. Then tighten the other side to get the desired backlash. This does two things 1-set backlash and 2- prelode the bearings. I have never lost a carrier bearing by having them to tight.
