For a second there, I was going to suggest it's 3.5 EB specific, as my 3.2 doesn't vibrate, but then lotuseater chimed in. So there goes that theory.
Reminds me of the infamous Sprinter Rumble Strip Noise, or RSN, as it became known.
It occurs to me that it may be a harmonic vibration... My Sprinter had one at about 65-70 mph, combined with the RSN. Learned to simply ignore it. Then I put in a boomin' sound system and all kinds of noises got ignored.
RIP Lemmy. Of all the things I've lost, I miss my mind the most.
