I think my truck is stuck in 4 wheel drive. I had a terrible squeek from the left front tire when turning slow in either direction accompanied by a wobble in the steering wheel. Now the squeek stopped but the wobble is still there. I pulled the tire and don't see anything obvious. I am guessing the 4x4 drops the front ds in the t case? Any tests to g\help determine what is going on would be greatly appriciated. Truck is an 04. 5 3500 DRW LWB Crew Cab w 6sp.
