My screeching accessory drive noise finally got bad enough that I thought the dealer would diagnose it.

Of course a year ago I asked then to loosen the serpentine belt and spin the idler pulley to see if one of the bearings was going bad.... But noooo, they couldn't find a problem and I doubt they did what I asked them to do...

I took it in today, it screeched about 10 minutes in to the drive instead of the usual 15-20 minutes, but of course idling on the service drive waiting for a service writer, it decided not to make noise when they got to me.

But low and behold they re-created the problem. And the diagnosis: an idler pulley bearing was going bad!

Looking forward to having both a silent shifter (fixed that myself) and a quiet accessory drive for the first time ever.
