From what I can remember, I'm pretty sure 93redbird is correct.

I meant the bearing seals were missing or destroyed and some ball bearing were missing .

Yes, the bearing failed because it was a bum water pump, they are supposed to last 100k+ miles and when they don't unless its related to poor maintenance I regard it as a bum water pump.

Probably not much value in saying this, but the factory pump in my '97 is still going strong at almost 130k...I've learned that part failures in these cars are tough to predict. If you talk to enough folks you'll find that it's like anything else - some last forever, some don't.
Hell, my stock Opti is still doing great....according to most people on here half the parts on my car should've died a long time ago.
Just the luck of the draw I guess...when I think about though, it's kinda funny - if GM's failure data shows say a 10% failure rate for WPs, Optis, etc., I bet most of that 10% has posted about it on an internet forum somewhere
