Sheet metal vibration

[4xquadrod]

I have developed a sheet metal vibration at a couple of different rmp levels. I haven't been able to locate it yet. Has anyone else had this and figured out where it is coming from? My exhaust is fine, not touching anything. This almost sounds like it is coming from the rear of the cab.

Just one of those little annoyances

Before you get into more complicated stuff, have you had TSB 19-008-03 done?



You can check out the TSB here: http://dodgeram.info/tsb/2003/19-008-03.htm

No I haven't had that done, but this is a tin sounding vibration coming from the back of the cab or bed. Sounds like sheet metal that worked loose.

I actually took a weight that you find on a retractable hose under a kitchen sink and attached it to the same area a year or two ago.

There's also TSB about buzzing from a small, riveted-on plate under the hood. Sometimes sounds originate from somewhere other than they appear to. This probably isn't your problem but it never hurts to look.
