Driving downtown with windows down, passenger side, there's a little whistle. It's not a whine, or speed related. I drove near a building wall, and from the passenger side you can hear it.

My first guess was something around the tirres, behind the tires...

Anyone had something like this?

 

This whistle is even if the car is in neutral running down a slope. However, in reverse gear it's not there, once back going forward, its heard. It's on the right side.

It's like some kind of a bearing, or a rubber somewhere became thin.... I just do not know what possibilities it can be.

Any ideas?

 

It could be the loose windshield moulding near A pillar on right side.

 

Maybe, if your lucky, a turbo is starting to grow!

 

That needs some speed right? Coz it's really on very slow, like barely moving... backwards no whistle, forward, yes. If I open my driver window against a wall, i dont hear it, maybe barrrrellyyyy.. but on passenger side, i can hear a whistle. Feels like middle to font... maybe front whee..

Not that kinda whistle

 

I don’t want to freak you out, but the drive shaft howl people talk about can start off like a whistle before it gets worse. Now if it was the drive shaft bearing normally it occurs at certain speeds only until it gets very bad and u can hear it with the windows up and from either side of the cockpit. This is probably NOT your issue, but at least u could rule it out. Also, check out your splash guards around the front passenger wheel well. Maybe a clip or two broke and it’s hanging making a whistle. Idk otherwise.

 

Thanks. Yea, I'm not sure it's that cause it's on one side (passenger). I recently noticed it get slightly louder if i press the brakes. But pads are thick enough. Feels like something in the wheel, either front or back; but seems more front.
