Take a listen and tell me what you think. First off, new Code 3 pulley bearing and new idler pulley were already installed trying to address the problem, but the noise got worse, not better. Chrysler dealer did the work and says it's coming from the Supercharger and that will be $6000 to replace. MB Tech did not think it was too bad but said it was not normal. They wanted $3000. I'm preparing to remove the SC and replace it with another used one I got off eBay for $1000. Has 18K miles on it with new Code 3 pulley bearing installed that seemed to be the problem that it. But won't be sure until I complete the job.
