This may be a stupid question, but I'm interested in keeping my 500E in top shape now that's its hit 100k miles. I've got a mysterious clunk in the driver's side front that is apparent at low speeds over bumps. I heard that shocks last about 100k, but what about all the bushings, tie-rods,wheel bearings, springs, etc. Do the springs degrade over time? Sway bar? I also understand that I should budget for the motor mounts going out around 100k in this car.
I believe that the clunk I hear is either a shock on its way out or the wheel bearing. Any other things to look at?
