I did some searching on this steering clunk and it seems most steering clunks for these trucks are caused by the intermediate steering shaft. I just bought this truck yesterday so it's still under warranty but I'd like to diagnose this myself before I take it in. My symptoms don't seem to quite match what others have described here but I only seem to feel this clunk through the steering wheel when I accelerate from a stop. Light, moderate, or heavy acceleration. I don't think its a clunk from the driveline, it really feels steering related. How can I confrim the problem? Thanks.
