Well, what I did was changed yokes thinking that the carrier had a solid spacer in it but it has a crush sleeve.

I looked in another source and it said to torque it to 175 ft lbs. Now i'm getting confused because I don't know which numbers too use!! http://www.fnc.ch/Technik/9-Inch_rebuild.htm

I have changed yokes with a crush collar over and over again.

it takes a 5 ft pipe on a 3/4 ratchet for me to crush the sleeve the first time, with the carrier bolted to a steel table.

after that i just impact it on and off, seems like every time i loan out a 3rd member they are running a diff yoke.

when holding the yoke in hand, using a impact gun it sure isnt gonna crush any more.

I have 500-650 all of them, no problems yet ever.

Thats what I was thinking because I have changed yokes numerous times and just ran them down with an impact wrench but The guy i'm helping get started has another guys gears in and when he heard that I had changed yokes to match his u-joint he felt I had screwed up his gears and was wanting me to torque the nut back on since I had just used an impact. I later found out that this is a stock type ratio so i'm not too worried about it other than now if they fail i'm the one too blame regardless of what the bearings may have looked like before hand.

I work on cars everyday and thats how I do it impact just don't get carried away cause you can damage the bearings.Like 66jj said it takes alot to crush that sleeve when setting them up.
