can anybody tell me the proper torqe for the pinion nut...so it will crush the crush sleeve on a chevy 8.5 10 bolt rear end?

I always use a Ingersol Rand 244 impact set on kill and sometimes it takes awhile to crush it. Yer pinion bearing preload will dictate if you have the stack up correct. If not-you get to start all over again. I keep spare crush sleeves on hand for that reason. Recheck yer gear pattern and backlash.

It kinda sounds like you don't know how to setup a rear end. If you have any doubt check out this article: http://www.pirate4x4.com/articles/te...sta/Gear_Setup

If you are unsure of what you are doing read up and pay VERY close attention to what you are doing. Otherwise pay someone to set it up right or you will regret it.

Generally when you are setting up gears you do not install a crush sleeve until final assembly (once you have found a good pattern). There is no torque spec for a pinion nut on crush sleeve style diffs. There is only a pinion bearing preload.

The crush sleeve generally requires ~400-500 ft. lbs. to begin to crush and then much less to continue crushing.
