First, I apologize for the horrible video quality. This is a video I took just minutes ago. A big... wheel on my engine is wobbling and making a not-very-loud scratching sound. It is wobbling worse than it looks in the video.

Yes, I know *nothing* about engines.

What is it and what can I do about it?

My Crossfire is under warranty with CarMax, so I'm going to call them tomorrow morning. I am terrified because I lost the receipt for one of my oil changes last year... I'd hate to lose my warranty on that technicality. I wish I used credit cards for everything, now. >.<

 

I would not drive the car.. at all.
Call carmax and tell them you have to have the car towed. Im not sure how good their service department would be about repairing a car like ours, I would see if they would let you take it to mercedes or chrysler.

Your water pump has either failed and the bearing let go, or its very near to death. DO NOT DRIVE IT, its not worth the damage it would cause if the pump shaft failed

 

In case it wasn't clear in the video, here is a picture of someone else's Crossfire, with an arrow pointing at the... big wheel thing.

 

Thanks for the info. I hate to hear it, but I will heed your advice and get a ride to work tomorrow. MaxCare's warranty department is open 7am-7pm.

 

Yea, its just not worth it. If the water ump is that far gone, its probably eaten the impeller up, which means little no water will be flowing through the cooling system, you could potentially blow one or both headgaskets, or do worse.

And if the shaft failed and the pulley came off, i would cause unholy destruction under hood
