I have a couple more videos and some run-out measurements I'll post tomorrow. I noticed that there isn't much wobble on the axle flange, but it is there with the brake drum.
I measured the back rim of the drum and the low spot was .065 back from 0 and the high spot .010. That's a change of .075 which is basically an inch.
I bought these from either Of Reilly's or AutoZone about 10 years ago. I don't see any balancing weight on the drums.
Could this be the cause of my problems?
