Sometimes the bearings just start making noise even if they don't leak or wobble.

I had one where the bearings got loose. It made rattling noises as the impeller hit the housing. When I took off the belt it was so loose I could wobble the pulley back & forth.

I think a broken shaft wouldn't hold the pulley in place & you'd throw your timing belt. Also, it wouldn't move any coolant & you'd overheat. Loose pieces of the impeller might jam it up, then you'd throw your timing belt. If I had any possible reason to suspect this, I'd take off the timing belt & inspect the pump really good. Throwing a timing belt is never a good thing.

Yeah, 'cause if it was any of the other stuff like hoses, he'd probably have figured it out by now.
