I'm "stumped" attempted to pull a tree stump out this weekend to no avail. It wasn't moving. my truck was in 4 lo. 1st gear attempting to pull if out. We heard a minor "bang" and I lost 4 wheel drive. Truck was stuck. Steering seemed locked up. Dug it out. Got it to steer and no 4 wheel drive. Took around the block then to the shop and noticed the steering wheel was off center? Also now the 4 wheel drive works? Anyone have any input on this? Let me know if you need more details? Also the front driveshaft spins freely when in 2wd? Thanks!
