Thoughts Needed Please

I recently purchased a yukon posi (DuraGrip) for the 8.5" 30 spline 10 bolt.

I went to install last night, only to find standard I.D. carrier bearings (1.625) dont fit, the Yukon Uses like, 1.781" ID bearings, so the hub might be close to 45mm.


Those bearings im having a kinda hard time finding, and naturally they are offered thru yukon.

Apparently, the large hub bearing is just a "thing" to accomodate aftermarket carriers (auburn, detroit, etc)

So its some marketing gimmick im assume.


Anyone see a reason i can't just chuck the yukon up in the lathe and turn the journals down to the appropriate press fit size for plain old standard 1.625" I.D. carrier bearings like ALL stock carriers use, i had to put the axke back together last night unfortunately, but i DID find the sourcr of my whining, and it was what i thought. The large inside pinion bearing and its race took some damage from the fall when the truck fell off of the lift, replaced that, set everything back up, and presto, the rear end doesnt whine anymore.


Please let me know your thoughts in turning the journals on my yukon. It is 10x easier, and faster to do that and go to any parts store and purchase the standard carrier bearings vs wait ANOTHER week AND drive on a welded rear end. Im getting sick of it. It sucks.

I’d turn it without thinking twice. You’re only talking .156” roughly you need to turn which is only .078” of material off the thickness of the bearing seat. Turn it and send it.

Ok, thanks.
My life has been a total disaster lately, and i just wanted some sane, logical opinions on the topic just as a confirmation. I personally saw nothing wrong with it, i just wanted to be sure.

I wonder if there’s a difference in alloy being the reason for more material being used?

I was thinking either the engineers used a different alloy or they wanted more safety margin because they assumed you were using more bald eagles and were going to be hooking up the rear end more. For your application I don't think it would make a bit of difference to just turn it down to the standard size bearing.

It appears to be a a better casting than the OEM carrier , some sort of steel vs cast iron
