My truck will feel like it is in 4WD even when it isn't
I noticed that my truck feels like it is in 4WD even though its not a few times over the last month. I have a 2011 Silverado, 5.3L V8, 4WD with 90k mileage. When I have my wheel turned slightly and take off (i will give it a little extra gas than necessary) I notice a stuttering while turning into a spot to turn around (usually turning left at low speed <10MPH). It feels like I am in 4WD even though I'm not. I will park and switch into 4WD and then back to 2WD but that doesn't fix it. When I turn the truck off and back on again it the stuttering stops and doesn't return. This has only happened 2 or 3 times and started last month but it has never done that before and it only does it when I first start the truck and go. If I am at a light or stop sign and goose it this doesn't happen, wheels turned or not. Anyone have an idea of what could be happening so I can get in front of the problem?
