I would have to say be a P. I. T. A. when it comes to getting service work. Clunking and clicking in the front end is not normal. I am not very well liked at my local dealership because I tend to make grown men do their jobs. :{ I usually try and have my issue diagnosed prior to my appointment as this tends to open everyones eyes and eliminate the "This guy doesn't know what he's talking about" syndrome. It sucks that you have to do the troubleshooting for them, but if you don't you know your not likely to get the issue resolved unless the part falls off of the truck.
