Check out the movement on the outer race...



This bearing started to fail in less than 100 street miles. Here in the first autocross lap I ran on it you can hear it already failing...Go to about 34 seconds in

Looks like a radial bearing, they don't handle thrust loads nearly like tapered rollers. I have radials in my 9" Ford, they were put in by mistake from the builder and I haven't had any noticeable issues so I haven't changed them out yet. Were they both bad? Wheel movement wasn't noticeably different from side to side that I saw. What surprised me is how much front to rear it looks like it flexes, like the whole rearend is moving.

Very cool videos, looks like it's working very nice.
