o ring/seal knuckle

[John_Conrad]

Getting ready to replace a bad wheel bearing/hub assembly on the front of my 1997 oldsmobile 88.

The repair guide shows an o ring and seal on the knuckle, am i looking at this diagram wrong and/or is everything already on the hub and bearing assembly?

Not seeing it in my info. There may have been one on the original hub back in 1997.

Thanks Trav, your pic is also correct for my model. I replaced with hub and bearing assembly only nothing else needed.

i think my book is, as you stated for much earlier years and does not contain all models/
