No grease and motor oil as a replacement? Would think that was not a good thing since bearing was suppose to be sealed and require no additional grease.

Reckon frequent oil changes and "proper" driving style saved the day for you.

Additional question: Was the original a singe or double row bearing?

I also own a 2000 S and as I understand it, 2000 was when Porsche used single and double row. Dis-assembly only way to be certain which one might be in use.

Perhaps someone else could shed more light on that fact or fiction.
