Windshield Weatherstiping

[stormrider]

Dumb question: but I just noticed that there is nothing across the top of the windshield on my truck. Rubber down both sides but that is it. You can actually feel the thickness of the glass. I have been in some real frog stranglers and no leaks but.....

Is this normal?

[punmax]

Yes it is.

It's a floating piece of glass. I'm not sure why they felt it would be better without a strip to seal the void. $$$ savings maybe? You'd think it would generate wind noise although I can't hear any from there in my truck.

You can thank Chrysler for that... Pretty much all Chrysler/Jeep went that way in approx.2007 and up.

 

But.If you look close their is a black weatherstrip. It's inverted....

Thank them for what? Is this a problem? Has there been any issues with this design? Or are we making assumptions again?

Actually the glass is bonded to the body with urethane and is an integral part of the cab. The seal is just a noise maker.

I am assuming, and Frank (Grumpy Aero Guy) can chime in here, that it was done for aerodynamic reasons as that is the highest part of the truck where the airflow crests. Probably advantageous to not break that airstream with a piece of weatherstripping.

No matter what the reason, it seems to work pretty well.

Sorry guys i didn't mean to be so harsh....Pretty much all manufactures are going this route now. ie v/wagon chrysler g.m. ford.etc.

Yes Your right.....And somewhat smart too.....

"Trim" around windshields on older cars was mainly designed to cover big ugly gaps between the glass and body. (I'm sure they also helped keep wind noise down). Now that they are building to closer tolerances, the trim can be really thin or nonexistent in places. I think that's a good thing!

HOLY HELL!

 

NEVER tell Jeff he is smart. It will be months before his head fits through the door again...

No worries, I am used to it.
