It only makes the noise when I'm in reverse, you can here it really well in the cab, I just can't put a finger on it.

Here is a vid of the noise:

did you double check to make sure everything is tight on it?

 

sounds like something is vibrating, doesn't sound like metal rubbing, oh you said you can hear better in the cab maybe some loose parts, like a plastic piece or something. huh

 

Thats the sound of coolness. Enjoy!

 

its not metal rubbing it sounds more like plastic vibrating but none of the plastic on the PS feels like it is vibrating. Somehow I'm going to have to check the engine bay while someone is in the cab.

 

Thanks!

 

anybody else?

 

if you have an aftermarket intake it's that! Last weekend I added a 1" BL and it rattled every time I turned on/off my truck or when I was turning left. At first I couldn't figure it out, but anyways got all fixed! Let me know if it was that!

 

Gonna have to get out there with someone to help you to diagnose this. I honestly havn't a clue.





how's those inner front fenders? How about the fan shroud? Is it timed to the speed that you are going...meaning...does the sound speed up as you speed up? Leave anything left unhooked or unbolted? Check everything that you touched. Sounds can be very decieving from in the cab...it sounds like its' passengerside, yet it could be driver side. I've had weird noises like that before.

 

You were right. It was starting to do it in park so I checked under the hood today and the metal piece at the end of the K&N filter was rattling against the metal underneath, Thanks guys, I'm sooo glad the noise is gone.
