there is no crush sleeve used in the 742 cases -- shims set the preload
the reason i brought this issue up is make people aware of this so when they try to build their diff they have a idea as to why the preload is giving them trouble.
never had any issues like this with any other major gear makers -- Motive ( Richmond ) , US Gear ,etc.
since US Gear , Motive etc. has stopped making 3.55 gears for the 742 cases , Yukon is becoming the only game in town.
