I'm getting a creaking noise when I'm in a parking lot, turning the wheel left or right and driving less than 5 m.p.h. (e.g., when going through a drive through). I figure it's either the steering damper or the control arm bushings/ball joints.

I'm going with the steering damper first, because the dealer has it in stock and will sell it to me for $55. The control arms are substantially more expensive. Last year, just before my 400E was totaled, I replaced the steering damper, because it was making a single clunk sound under the same circumstances.

Anyone experience a similar noise and figure out what was causing it?
