I have a 01 2500hd truck. When I'm about to turn in to my sub division,i hear a pop sound, like maybe something rolling from one side of bed to the other. I've just had the wheel bearings checked and everything lubed. Truck drives fine down the road no noise or anything odd while driving. Only does it at this one street. Please help. I've checked u joint on drive shaft, no play, I checked sway bar. Just don't know what to check next.
