Hi all, my '95 Montero SR has a weird vibration that I cannot figure out where it comes from. At 2350-2500 rpm there is a tinny (as in tin can) vibration from somewhere underneath. It will make the noise in park or while driving. My best guess is that it's a heat shield or something because the sound is not heavy but high pitched. It only does it at those rpms. Ideas?

 

yes, could be heat shields - or pipe hangers?

 

my ram does that. it is the CAT heat shield i believe.
