I've been getting some vibration from 1800-2200 RPM. Originally I was thinking it was a bad flex disc, but my shop is saying that it's the pulleys. I've replaced all the pulleys with a Shardul set and have a bwk. Could it be the s/c bearing?

Put the car on a lift--run the car and inspect the drive train----wher is the vibration!

its at the shop and they have it on the lift... It's also an E55 so I'm in the wrong forum.
