Moose my crank pulley did the same thing, even after a swap. I think the face of my crank snout wasn't machined "flat" with respect to the perpendicular plane of the crank axis.

40,000 miles with the replacement pulley, no problems so far...

 

That is a pretty neat trick.

 

old school. Used to do this on fwd vehicles when the crank is right up next to the fender well or frame and you couldn't get an impact on there and I needed to replace timing belts.

 

Mines not nearly as bad as yours! Where's that video of yours, I remember that death wobble.
