Picked it up yesterday afternoon. The supercharger looks new, the noise is gone and I am happy. Ontario (CA) Jeep/Chrysler has always done a good job for me.

The job took two days because all the parts weren't in the box coming from Chrysler. Perhaps because of the extra day, I was not charged the $100 deductible from my extended warranty. Seeing the number of posts that said they had the same problem, it could be one of those "hidden" warranties covering the supercharger.

And no, they sent my original unit back.
