Pinion Bearing Preload HELP!!!

[Execrator]

Ok so I'm doing some gears on an 8.8 for a friend and when I went to crush the sleave to set preload to where it's needed, minutes later the preload increases. It went from 22 in. lbs or so, as I had set it, to like 35 in. lbs in 5 minutes without me even touching it. What is going on here? Someone please help as it's frustrating and I'm running out of crush sleaves.

I just checked it again before I posted this and it almost seized up!

Is there oil on the bearings?

Did you make sure there was no grit on the bearings when you installed them?

Is the ring gear in?

Do you know what you torqued the pinion nut too?
