Rear end problem help

Monday I'll be able to knock it out fast but the green bearings that the guy insisted on sending for free showed up.

I wouldn't waste my time and effort changing the bearings, I don't believe for a second that will cure the problem. Just my 2 pennies. The pattern is probably a little off and allowing the howl on the coast side is my guess. Also there are some gear manufacturers that had issues with howling, this has been a few years ago this was discussed.
