I have a 2013 Silverado crew cab and when I drive with four people it makes a humming or rubbing sound in the back when I take off then it stops. What can this be?
I might be the exhaust rubbing somewhere in the rear. Ken, how big are those girls you are hauling around??
Lol.. No big girls. It also only does it when my custom rims are on too
Custom rims and big tires? Maybe a tire rub at the rear when loaded down?
