I'm OLD SCHOOL!!!

 

When I told my service advisor at my local Hummer dealer about my roof vibration niose at high speeds on my H2 , he immediately said it was the widshield piller posts, he had an outside glass company that they use come to the dealer and seal the sides of the windshield under the trimHopefully end of problem, he was confident that the problem was solved. I need to get it on the freeway on a windy day to make sure.

Good Luck Gary, Let us know how it works out!!!

 

Welp, we finally experienced the same noise today while going to Paige's parents lake house. I was driving about 70-75 and the rattle was driving us crazy. I need to do as you guys say and fix it. The wind was pretty strong so that must be a huge factor.

Funny thing, on the way home I was driving the same speed with no rattle at all. I think it all depends on how bad the wind is outside.

 

Went to the dealership yesterday afternoon and got them windshield rattle fix. We have 38K miles and they still fixed it. Also fixed some PI that had to do with a popping noise in the front end. Didn't charge us a penny.

This is a good dealership. It is Carl Black Hummer in Roswell, GA.

 

that's common on H2s, and its related to those fake air intake bumps on the left and right sides of the hood area near the window.

i corrected the rattle on my truck this way:

1. remove each bump (they pop out, and are held by 4 typical GM pins, which are great as they snap back in). The fake intake bumps have positioning pegs near the snaps, which tend to break off. This hasn't caused much trouble fo rme.

2. dynamat the entire inside of the intake bumps, and all of the area under the intake bumps

3. replace the bumps


That did the trick for me, AFTER i also tracked down a vibration (and treated with 3m tape) in the dash piece under those bumps that spans the whole front of the truck right in front of the windshield.

I took some pics of the problem areas and the fix, and i'll try to remember to post them.

But

A) focus on the area around the intake bumps
B) space with foam tape and/or Dyanmat all possible offending pieces


Its real easy.


This is a case of the styling of the H2 kicking us in the rear. The horrid aerodynamics (a result of the styling) cause alot of turbulence. But its easy to fix, and the big truck remains as cool as it'll always be.

 

Just did the full meal dral to mine, no more noise. I thought it was the wind deflector for the sunroof making the noise.
Nice and quiet, or as quite as a brick can be

 

Thanks for the help. Roll Tide
