2006 Suburban Z71 5.3L

So, this has been going on for a little while. I'm at a stop and accelerate normally and I hear buzz/hum for 1 to 2 seconds. I have somewhat narrowed it down because it doesn't buzz/hum when I turn off the StabiliTrak System. The tranny seems to shift just fine and I don't hear anything wrong with the engine. I'm assuming there's a sensor of some sort that is having issues with either the StabiliTrak or TCS. So any help with figuring this problem out would be greatly appreciated.


On a side note I had new tires put on recently and the shop couldn't figure out how to reset the tire pressure sensors so they correlate to the correct wheel location. The shop couldn't figure it out and I checked my manual and I didn't see anything about it. The reason I know it's not right is because I had a low tire issue before the new tires and it always said it was a different tire than the one that was actually low.

Thanks for your help,
Mike

 

I should also add that I have no codes active or in the history. I was thinking it might be a wheel speed sensor. I have tried recording the noise but have been unsuccessful at capturing it on my phone.
