H3 Weird Sound

[DixxieH3]

I wanted to ask anyone who might know why my hummer h3 2006 is making a rattling noise in the front passenger side. I've been looking, and I can't seem to find what is causing it. If anyone could help, I would much appreciate it.n

Look underneath for heat shields; they are notorious for breaking/cracking and then rattling.

What he said - especially the heat shield on the exhaust manifold.

Okay thanks I will take a look. This morning there was no sound, so I will for sure take a look.

My bet is the exhaust manifold heat shield
