Rather than post a mile long post about my '01 C320's development of a desire to turn right, I will just say that a 30 year tech at my MB dealer, using their new MBUSA required alignment rack, corrected my car's problem with a tiny change in caster on the right side. Took two tries, but he did it. I removed the 17" AMG C36 wheels, reverting temporarily to stock so as not to introduce any variables. Still great after a year.
