So I'm driving my truck into town this weekend, and I forgot something at the home, so I go to pull a quick U-turn. The noise that comes from the ass-end of the truck sends shivers up my spine. A massive clunking noise. Now I'm all worried that something snapped. So I park it on the side of the road and drop underneath to take a look but cannot find anything visisble. So I take off and drive it home. no noise until I go to turn into my driveway. It seems the clunking only happens when I turn. Anyone have any ideas? I was thinking the side gears are perhaps binding.
