After reading posts and viewing other videos, I wanted to post my own issue to confirm what I already suspect.

Here's the video: SC Pulley Clutch Noise.MOV - YouTube

You may also notice in the video what appears to be "chaff" from the serpentine belt.

Just hoping it's only the bearing and not the clutch!

 

Sounds rather nasty. The clunk noise cannot be good. I bet the specialists will come in to this thread and let you know.

 

Anyone care to chime in?

 

I agree that sounds pretty bad. I have had a bearing start to go on my SC pulley before and it started to "whir" .... there was no banging sound like I think I'm hearing from yours.

The next step I would think is to take off the belt so you can see if it is coming from the bearing in the pulley OR from inside. I don't mean to cause unnecessary alarm, but I would NOT start that engine until I isolated this further. Not that I've ever heard of one failing on this particular SC, but if you have something going on in the gear-drive it could go ballistic.

good luck ... I hope it turns out to be something minor,
Chris
