I've had a weird issue with the rearend in my car. We noticed the wheels were wobbling in the back one day while it was up on stands. (This during the 331 conversion over a year ago.) We took the wheel off, still wobbled. Took the spacer off, still wobbled. Took the caliper and rotor off, still wobbled. Next step ended up being 31 spline upgrade.
The car STILL does this. So I pulled an axle out. Took it to a driveline shop to get checked out. The new axle checked from centers is 20 thousands off where the bearing rests. It's 10 thousands off on the face of the flange where the rotor goes.
I was told the 10 thousands isn't terrible for the flange, but to figure this correctly I really need to take into account when it's installed it's basically figured by the bearing ride area. In other words that section is not too good. So it could make the flange wobble worse as the axle slides around a bit.
The new axles have 1,500 miles on them or so. (I only checked one, but the other is showing a slight wobble as well.)
The shop recommended I check on sending them back. But they said they would check the replacements before installing them.
