2nd Gen Non-Engine/Transmission Buzzzzz

[MuddFlapp]

My truck seems to have developed a buzz that I can't find. Under power hauling my horse trailer I noticed it around 2500 RPM a buzz that sounded as though it was coming from under the dash or down close to the floor. I thought it might be the shifter rattle (I've had a bungie on that for several years), but I can't stop the buzz by applying pressure to either shifter. Is it possible that the buzz may not stop even with pressure applied to the shifters?



Thanks,



Gene Earl.

Had a buzz in my truck too, even when it was shut off... realized it was my Braun electric toothbrush.



If only life could always be that simple.

Just a guess... boost line vibrating against something?

I have the same exact thing going on, mine also happens w/o a load @ 2200 rpm. While installing some gauges this weekend, I noticed that I was missing a exhast manifold bolt on top of #6. I think that might be the cause of my buzzing.
