Sounds like a bearing going bad. Remove the serpentine belt and rotate each engine accessory by hand. You should be able to isolate the problem.

weird sound and smell
WE have a 97 awd safari. We have been hearing a wierd noise, and since its a new vehicle to us we wondered if it was normal. It sounds like a gear driven timing chain or a supercharger. It speeds up with the engine and changes with the shifts of the transmission. Also there is a smell, like a burning clutch. The smell seems like its from the front wheels. I just did brakes and I didnt notice a stuck caliper or anything. Im not sure if its just a new smell as the pads get seated or what. Any ideas?
