jbors -- Although there was no asymetrical tire wear, I was experiencing a seemingly similar clunk about a year ago on a '99 ML 320. I must admit that my diagnostics were not as thorough as yours (i.e., uphill/downhill differences, etc.). However, once both right hand front stabalizer/sway bushings (at the frame-mounted link and at the lower control arm) were changed, the problem was no longer evident.

Hope this is of some use to you.
