Hey everyone, it's been sometime since I last posted but I'm back to making a list of things to upgrade/fix on my 2004 H2 hummer.

the biggest problem right now is this loud vibration noise. No idea what it is... here's a video I took of it. Any ideas?

thanks for the help.

 

heat shield from your exhaust

 

Thanks.... is it possibly loose or could something be wrong?

 

Just found some older posts on this... thanks for the information

 

That is exactly what I would have guessed. You can most likely bend it out of the way.

 

Had the H2 into the exhaust shop a few weeks ago and they couldn't find anything wrong.... not sure where to go next with this.

 

I just had mine fixed again. If it keeps breaking I would need a new piece of exhaust. Good excuse to make it a little louder

 

nlhummer do you think you could take a picture of where you had to fix it ?

 

There is a heat shield on the catalytic converter that comes off. You can tak it back down with a weld or replace it.

 

Now I just have to find out where this is
