Verify the suspension
If you encounter a clicking noise on your Mercedes Benz S Class each time you pass a speed bump, it is really possible that your suspension block is the reason of the sound.

To verify if this is the problem that worries you, take a dented road and, at low speed, listen to the sound coming from your front axle when ever you pass over holes. If these are the cups, consider changing them as soon as possible as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Mercedes Benz S Class at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a cause. To verify the condition of the spring, position the vehicle on a flat surface and measure that the heights from the ground to the bottom of the body are similar on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too significant it denotes that most likely your springs are worn, if you discover a leak go a little further in the article to have the answer to this problem.
