Since I bent the heck out of my front axle housing, I wanted to look at the rear axles. I put the Jeep on Jack stands and used a Sterett run out machinists gage against the perimeter of the wheel lip and rotated by hand to find the zero point, and then rotated to measure total run out on the wheel face. Now, I'm doing this out at the edge of a 17" wheel, so my measurements are exaggerated compared to measuring at the hub face.
I got a total deflection of 0.034" on the drivers rear wheel, and I got 0.016" total run out on the passenger rear wheel.

It's there some acceptable out of plane that is known, or is it expected that you should see zero or Damn near it?

I would not worry about it unless you can feel it when driving.

If you think your Flange is bent you need to remove the tire and wheel , Brakes and rotate the axle. Take all the other variables out.

Those numbers you posted seem tiny to me. Once my son slid sideways into a curb with his TJ. The back wheel then had a wobble. I bet it was out about 1/2" runout. I found a used shaft on eBay and replaced it.

We put mine in a lathe to spin it and it was clear that it was bent but it also made noise, the pad was rubbing the rotor causing a squeaking noise. The shaft once removed looked fine but once we put it in the lathe it was bent pretty good.
