This is the true reason for these forums....things like this right here...
When i accelerate at about 20% throttle....no matter which gear...always 20% throttle...1.5-2 rpms.. i get a squeaky noise from...under? my truck. i cant pinpoint it cuz im always inside when i hear it...obviously...so anyways does anyone know what this could be? if someone says brakes i will do everything in my power to become and admin and ban your IP adress, it might take a year but it'd be worth it. hah
its not LOUD but its always there and annoying, kind of embarassing coming out of my beautiful truck. help. please.

 

I bet your brakes are bad! lol!! j/k, don't ban me!

What kind of sqeak is it? Is it high pitched? Is it constant or is it like a bird and sayschirp chirp chirp? Need more input trucky----- (said in the voice of# 5 off of Short Circuit)

 

high pitched and constant WHEN my foot is down the same amount. if i hold it in one spot it wil squeak allll day. its as if when the pistons go at 1700 rpms they want to squeak i duno

 

maybe the mouse under the hood is telling you to feed it. sound like the serpentine belt is riding on the idle pully funny. or the bearing is going on on of the accesories

 

Yeah, if you oil that hamster wheel it should go away!!

Does it happen only when the engine is under load, like if you were accelerating or if you are just cruising down the street, or will it do it if you are stopped in neutral with your foot on the gas?

 

tell your freinds it's the supercharger. yeah, I'm alotta help.

 

no never at idle...only when im rollin with the pedal down. i can either floor it everywhere i go or go 0-60 in 5.6 days but the average throttle is where the noise happens

 

I had a similar problem with my 06 Dakota. The heater hose mounts on the front of the intake manifold were loose, causing the heater hoses to move and 1) vibrate against the air tube going to the throttle body and 2) move the accelerator cable around causing an annoying squeak that only reared its head at part throttle. Both noises sounded like they were interior noises.

 

Yeah, the only thing I would do if I were you to check all of your connections. Check all of your hoses and electrical connections and make sure everything is secure and not touching anything else. I'll bet that you find something rubbing somthing it shouldn't just because it only squeaks at a certain vibration, or engine load.

 

I have this same issue, and I notice you have the K&N air intake on yours as well. I have always thought it might have something to do with that, but it isn't constant for me, it's only on a cold start that it happens.
