2002 F350 4x4 CC 38,000 miles. I was wandering what T/C sounds like when going bad. I have a rolling, shaking rumble sound in front end area that is noticeable while rolling slow or driving up to 25 mph. It does it coasting in neutral or driveng slow, it sounds and feels like rolling over a gravel road. It sounded to me like a bad baring but had it at a shop today and they lifted it and checked barings, shocks, tie rods etc. and found no problems.
