I have a 92 190E 2.6 and the steering damper is only $26.95. I would check a internet wholesale Mercedes parts stores to find a better price. You should be able to do it yourself, but I would find it hard to believe that it has went bad in five years. Does the car shimmy when you drive it or jerk the wheel when you hit bumps? In either case, it probably something that can be done by you if your mechanically inclined.
