Well we're in Maine, the van was a real trooper on the way up, 23 MPG fully loaded!

However, the "new" noise was present at low speeds, getting on/off the highway etc.

Once we got unloaded I did some checks on the country roads here.

You know what I found? For whatever reason, this new sound I hear goes away when the drive axles are engaged (hubs in "lock"). Specifically, the passenger side one makes the sound go away when engaged.

This is really kinda hilarious, as I changed out the auto hubs to begin with BECAUSE the passenger side hub wasn't disengaging and the drive axel was turning.

Why would this sound go away with the hubs/axel engaged? I'm just driving with the one engaged, to not hear the noise.
