Release the belt and turn on the motor and see if the rumbling is still there. If not it is the arbor. I would replace all four bearings as long as you have the top off. I would say the grease has reached it's service life and has dried out.

In my heart of hearts, I figured this (bearings) was going to be the consensus. Looks like I'm going to get real familiar with the inner workings of the tool, so we'll get to add that to the shop skills list. Also a good time for me to re-tune the miter slots to blade etc. More soon as I give it a try
