Just a shot of my van on escape rims. Picked up for 200 with minimal curb wear.

I have a thompson surface grinder. 30hp spindle motor. It makes alot of noise when its spinning down. Is it the rear bearing or something else?

I have minimal chatter considering the overall condition of the machine. This started after the key on the impeller broke and jamed up the head. I took it all apart and cleaned. The noise came after that. However it grinds better than ever. Do I just need to change that rear bearing? Or is it much worse?
