After 17,000 miles I started having a rattle in felt in the steering wheel at low speeds on minor rough roads. Brick roads were the worst and it seemed to be the worst during mild turns. I took it to my favorite dealer and they replaced the upper steering shaft and also the lower steering column support bearing. All is well during the 55 mile drive home. Unfortunately the two dealers close to my home don't know their butt from first base thus the 55 mile drive, but worth the drive. The dealer told me they have had 3-4 other trucks with this same problem. Have any of you had this rattle/problem? If so, maybe the above info will help you. My truck is bone stock. Ed
