I recently replaced the front suspension on the R129 SL500. Last night I was driving and noticed that the xenons were both pointing down limiting the projection distance. Previously, the lights would do their startup dance, but not anymore.

I was wondering if I messed up the leveling apparatus on the sway bar but when I checked just now, the arms were still connected. Is the leveling arm supposed to move at startup when turning on the lights?

I removed both the headlight housings and I can hear the leveling servos do their thing at startup, but the lights don't move up and down. Any ideas how to repair?
