Metal on metal grinding noise coming from belt area.
Forgive me if I am in the wrong section, but I was directed here from ClubGP in regards to a Bonneville issue I am having with my 2000 SSEI.
Recently, I took the car into the shop to have the intermediate shaft lubed in order to get rid of a grinding noise issue I was having when turning the wheel. Well, I few days ago I decided to drive it into work since my other vehicle was in the shop and noticed an almost metal-on-metal grinding noise being emitted from around the belt area under the hood. The noise will be apparent when I first start the car and then it levels out and all but disappears. I can also turn on the AC for a few seconds and activate the compressor, but when I turn it off, that same noise comes back and then, again, disappears in about 10 secs.
The care is completely stock, and based on working with my 04 gtp, I highly doubt it is the SC since it still makes the noise even though it is not activated. I have heard similar issues with regards to this as potentially being a tensioner pulley, but I have yet to hear what it sounds like when they go bad. Is it sort of like hearing burnt-out bearings (slight whining/grinding sound)? If so this may what I have on my hands, but I wanted to check with the Bonne crowd before tearing things apart.
