[QUOTE="kevinp, post: 10448477, member: 106826"] Thats what two dealers have told me, normal. But if yours is that loud I cant see how that can be normal. Post up a video.. Earlier today I warmed the car up where I could plainly hear the knock, turned it off, whipped out a knife an cut off the A/C belt and to my surprise it was 100% gone. I drove it for another 20 minutes and let it idle for another 10 minutes and for the first time since I bought the car the noise is gone (cant feel it on the VC anymore either). Surprised the heck out of me, the supercharger drive I'm putting on adds a spring tensioner (I cant believe Ford uses no tensioner) to the A/C so I'm curious to see if it comes back when the A/C compressor is hooked back up. I have no idea if yours is the same noise, too bad you just cant easily pop the belt off and see real quick. [/QUOTE]
