2014 Silverado LT 1500 4x4. So i was coming back to work today and i chirped the wheels in the driveway as usual... Then I noticed something funny as I pulled into one of the stalls. As I made the sharp left to swing into the spot I felt like my truck's 4x4 was engaged. I say that because I had to press harder on the gas pedal and it felt like the rear tires weren't pushing the truck. It was reminiscent of being on the trail and hearing the engine push harder to get the tires going. In any case, I pulled in with the rear left wheel hopping and semi dragging. I was going no more than 5mph BTW. So i straightened the wheel and backed straight out. The truck moved just fine. As I turned the wheel to swing the front end left in reverse I could hear the rear left wheel "hop" on the asphalt/rocks. I stopped and turned the traction control on/off. I then pulled forward a little in a turn and same symptoms. I then turned the 4x4 from 2wd to 4 hi and then back to 2wd. After each engaged I started turning right to go down the driveway with the wheel still hop/dragging. So I deliberately hit a bump to see how it would act. As the crest of the bump i heard a LOUD pop. After that I could turn the truck sharply and the rear wheels wouldn't bind. It was back to normal. Any thoughts?
