Transfer case output yoke -- how tight?

A few weeks ago, I was under my red truck and noticed the rear drive shaft has some movement to it... traced it to the yoke on the back of the transfer case... nut was lose. So I tightened it... and good! Found a socket from my 3/4" drive socket set, and cranked on it...

Hindsight, I started wondering if maybe I have now tightened it too much... is there any adjustment, or crush sleaves like with a pinion berring? Have I done damage to it? Any insight would be helpful...

It's funny, I thought you would have had an answer from one of the more knowledgeable members by now. I don't know for sure with these trucks but on my Jeep and my older Blazer, the yokes were bolted to the output shaft with no crush sleeve or anything like that. I don't see how it would be any different. Just my 1/2 cent FWIW.

Thanks Sean... I agree, as meny people who are tinkering with these trucks... surely someone would post... Thanks for takin' the time. You renewed my faith in the .org....

So it would seem that the yoak will bottom out on a solid surface, and berring adjustment or tention isn't an issue? Just crank it down and keep it tight? My concern comes from a noise I've been hearing... but hope it's not related. There is a "wherrrrrrrrring" noise I can't place... sounds like a wheel berring just doesn't feel like it, and it's a new berrring. Less than 2K miles on it. I've felt un-easy about how tight I made the yoak nut ever since I did it... just been buggin me.

Well, you can look up torque values based on the size of the fastener. It's application is kinda moot. I do use red loctite on driveshaft flanges/yokes. Gitcha torque wrench and go to town.

I don't have, nor do I hope to need, a 3/4" drive torque wrench... the question was more along the lines of over-tightening berrings... in some situations, tightening the nut in the center of the yoak adjusts the berring tightness... was afaid I had possibly damaged the output shaft berrings, if this is the case in my situation.
