Anyone familiar with the Eaton M90 supercharger? The one on my 1998 Grand Prix GTP is making noise, not sure if it just needs a new nose or a complete rebuild. I know about the coupler inside that can rattle, and it does have a tiny bit of play, but I think its more than that. If I take the nose off...what can I check for that would decide one way or the other?
BTW...its got 170,000 miles on it.
