did you find the problem?

I have a 2014 GMC Sierra crew cab 4x4 Z71. Recently I noticed a humming noise coming from the driver side only when going 55mph+ It goes in/out and last about 1-5sec and stops. I could feel the humming noise underneath the floorboard. It doesn't cause my truck to shake or the steering to do anything unusual. I have replaced the hub/bearing thinking that was my issues but the noise I still there even after the bearing replacement. I have been to 2 mechanics and none of them could diagnose the issue or where even the noise is coming from. Anyone else experienced this and found the issue?
