I have the notorious front end clunk. Since I have the comprehensive and certified platinum extended warranty, that covers literally everything but brakes, belts and body/interior panels, I am taking it in, and will advise everyone what the issue is, so as to help people who have the same problem.
Front drivers side clunks (sounds like near wheel well) when going over certain bumps, and almost every time i turn right and back again (doesn't have to be all the way turned), and sometimes when hitting the brakes.
For those of you with the same problems, I will advise what the techs say tomorrow. Feel free to ask "does your truck do this" questions to see if your problem is the same.
