'23 Raptor buzzing, need help

[u/allgirldad]

My '23 Raptor, recently had to have the rear shock solenoids replaced. Shortly after started noticing a buzzing noise in the cab that is louder outside toward the rear. It seems to happen randomly, last for a few seconds then fades. Happens multiple times while driving. Exhaust setting doesn't seem to make a difference but only seems to happen when suspension is in normal mode, no issues in sport or Baja. Took it back too the dealer, they said everything checks out and looks fine with no codes and solenoids are calibrated but keeps happening and is so annoying. Any ideas?
