Verify the state of the gimbals
One of the most regular causes of a clicking noises in the direction of your Mercedes Slk is linked with the direction of the car. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can generate a ticking type of sound when you get closer to the stop zone of your steering.

To check if this is the issue that concerns you, take a dented road and, at low speed, focus on the sound originating from your front axle when ever you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
