Default some weird noise or something?

So i was driving home from work today and i noticed a weird noise thats almost like a chirp. The thing about it is i can only hear it when i am in gear and coasting, not pushing the gas and not in neutral. There isn't really anyway to be able to figure out where its coming from since it only does it when it coasts and not while its parked. When it does make the noise it doesn't make a constant squeal, its almost like a knocking noise or somethin. Any ideas as to what it could be? Thanks

What's the condition of your belt? Is there anything around the belt/pulleys that looks like it may be contacting them? What about the fan?

Unfortunately, the cam sync on these trucks develop a chirping sound when they start to fail. This part is serious because it controls your oil pump, and if it completely fails, then you lose oil pressure. So we definitely need to make sure that isn't your problem.

Default Re: some weird noise or something?

i replaced my belt last year, and i also replaced my tensioner pulley. I don't think anything is rubbing on the belt or pulleys because it only does it when i'm coasting and in gear and isn't a constant noise. When i'm in 1st it can be pretty loud but a slow sound almost like when something is rotating it rubs on a seal or a gasket or something of that nature that is causing the noise, 2nd is like a faster rubbing sound. It almost sounds like it has to do with the drive shaft or something because when i'm driving i can hear it coming from behind me or beside me more so than in front of me. To me the key thing to understand is that it doesn't do it when i accelerate, when i let off the gas and in gear is when it makes the noise. and it also won't make the noise in neutral or when its parked. Thanks for the help man.
