The control arms on the front suspension of the Mercedes W204 will wear out over time. If you are feeling a loss of tightness in the front suspension the best thing to do is safely get under the vehicle and preform a visual inspection. If the pressed in rubber bearing on the cross strut control arm is starting to go bad you will see that it is not sitting symmetrically in the strut or cross-member and if it has failed you will be able to see missing rubber. If it looks like it is going safely raise and support the vehicle and check for any movement in the bearing

Mercedes makes a special hydraulic bearing press for removing and installing the bearing in the chassis end of the strut but I was not able to remove the bearing using a standard set of bearing removal tools and needed to completely remove the strut and use a press to replace the bearing. This article will show you how to replace the complete arm as well as just the bearing.

Note: Mercedes considers all of the hardware to be single use only and must be replaced with new.
