This is my first single can truck so maybe this is common, but when I put both windows down and get above like 20mph I can hear a very high pitched whistling. Is this how single can trucks are because there's just not much cabin room, or is my back window leaking possibly?

 

Throttle-body spacer?

 

It's definitely coming from inside the cab, like wind noise. Can I put a head of clear silicone around the back window?

 

Do you have a sliding glass window?

 

You are driving a Dodge Ram, and our trucks are about as Aerodynamic as a Brick with Wheels.

What you Might be experiencing is wind coming through the top portion of the door seal, you should inspect your door seals and look for dry-rotting of that black weather stripping type seal. That is the most common.

Also with some trucks there is a whistling noise from the side mirrors...

Sliding glass window is also a possibility... pain in the *** to do.

 

SOLUTION:
LOUDER EXHAUST!!!!!!


Or rock music to **** off the Prius drivers.

 

No sir
I will check those things out. Thanks for the tips.
Haha yeah thats an even better idea, it will be annoying still though when my 7 year old is in the car with me and I cant blast the music lol
