Rattling/ tinning sound from passenger side

I figured it out!! Try dealerships are a bunch of dumbasses I seriously can't stand any of them. I took my jeep in and they said it was fixed and it still made the noise later that day!! I got under my jeep and bagged around with a rubber mallet and found that either the catalytic converter or its heat shield is loose or vibrating. So I am taking it back to the dealer now that I have figured it out. Isn't it their job to figure this stuff out? I love that I love to work on my jeep and figure things out but dude I am in physical therapy and I figured this out in 10 minutes...they actually went to school for this...they had my jeep for 10 hours yesterday and said they fixed it...wow. For all of the figure-it-out-yourselfers keep up! And if you have this rattle/tinny sound upon initial acceleration at a green light check your catalytic converter heat shield because it's probably the culprit!!
