I just had a new rack and outer tie rods installed about a month ago. Went turkey hunting and climbed a rocky hill in Missouri. After getting back out on the main road I noticed the steering popping when I turned the steering left and right with the engine running and sitting in park. Doesn't do it when driving unless I'm going extremely slow (backing out or turning in to parking space). Something happened on that hill. Truck drives fine. Just an annoying pop sitting still turning the steering.????
