Verify the suspension

If you experience a clicking noise on your Mercedes Benz GL Class when you pass a speed bump, it is highly plausible that your suspension block is the cause of the sound.

To examine if this is the problem that worries you, take a dented road and, at low speed, pay attention to the sound coming from your front axle when you pass over holes. If these are the cups, consider changing them soon as this may affect other parts and require more expensive repairs.

Check spring and cylinder

If you detect a clicking noise on your Mercedes Benz GL Class at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a cause. To examine the condition of the spring, place the automobile on a flat surface and measure that the heights from the ground to the bottom of the body are equivalent on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too large it denotes that most likely your springs are worn, if you see a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, be sure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should think about replacing it or them.
