I need to clarify; I think the issue with the bearing spinning is with the inner race spinning on the axle housing which requires a Redi-Sleeve to repair. This isn't intuitive, at least to me, since the 'big nut' should clamp the inner race, but apparently it does happen. At any rate, if the gasket is too thick--thicker than the O-ring--you will get a pretty back leak of diff fluid.

Ok, the paper gasket is NO WHERE NEAR as thick as the O-ring so I'm hoping it will be ok.

The O-ring fits in the groove in the hub, so it will be much thicker than the gasket. The outer race of the bearing plus spacer needs to be 0.001" to 0.004" higher/proud than the face of the hub so that, when the lug nuts are tightened, the outer race of the bearing is clamped between the hub and axle flange and can't turn relative to the hub. What happens with gaskets that are too thick, that clamping doesn't happen, and the outer race spins and wears the hub out.
