thats cool man fair enough, but think about it, that is the correct way to do it ala proffesionaly rear end servicing manuals, why take a chance when it is way more expensive to replace everything later on cause the pinion bearing preload was out of spec. It says specifically that once the crush collar is tightened and then released that it should be replaced and won't hold tension properly. Peace guys good luck

I agree that's what the manual says.
If you don't feel comfortable doing this or anything else mechanical -don't. But I can give you a couple of different examples of things I've repaired on my own personal vehicles (on rear axles among other things)and then driven for years afterwards that should not have worked according to the manual. I will emphasize here again the words-it's all in how you do it. There is a certain mechanical savvy that needs to be present for things like this to work. Some people have that touch and some don't.
Sometimes things occur for reasons not totally clear at the time. A good example has recently been stated here. The use of Loktite as a gasket sealer is a good example of this. Somebody somewhere decided to try it and it worked for them. Does it say anywhere on the instructions for Loktite to use it as a gasket sealer? I can assure you that RTV works also-use a quality type like Ultra Blue, spread it thinly and assemble. No -it doesn't all push out on me, maybe it does on someone else. RTV is made to be squeezed thin and retain sealing qualities. It's all in how you do it.
I'm not interested in arguing about does it work or not-it does work for me and has for a long time. I've been a professional tech for over 20 years.

Me personally I just like to do stuff right the first time instead of having to spend more to do it again so thats why I take out the carrier and install a new crush sleeve to the correct specifications when installing a new pinion seal. Peace

no prob-just trying to clear up what I meant. As I understand it-you can replace the crush sleeve with a precision machined spacer for better strength under loading like you're doing. You crush one down and measure the length-then make a spacer that thickness. Just an idea.
Sounds like GM redesigned something-that sounds like the best way to do.
