Things I've learned in this process...

I ended up reusing my older idler pulley (worked fine, not noisy, still feels full of grease)... definitely needed a new tensioner pulley though. I assume since both sides of this tensioner pulley bearing leaked a bit, it's due to the break in process where the centrifugal force pushes out a bit of grease, particularly when it warms up. The wobble on the Dayco idler pulley, however, was completely unacceptable and I will return that. There can be some play when you test it out with no tension, but once tensioned, this noisy wobble is no bueno.
