Hey guys I bought a used 2019 ram 1500 a while back. It’s a 2wd and the build sheets says it has a Anti Slip rear differential. However during a light off road trip. A friend of mine noticed that only one wheel was spinning on a difficult spot. Next day I jack the truck up put into neutral spun the right tire and the left tire barely spun the opposite way. Does that mean I actually have a open differential and the build sheet is incorrect ?
