Examine the suspension
If you encounter a clicking noise on your Renault Scenic 4 once you pass a speed bump, it is extremely 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 damage other parts and require more expensive repairs.
Check spring and cylinder

To verify the state of the spring, position the car 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 verify between the front and rear, if there is a gap too significant it means that most likely your springs are worn, if you find out a leak go a little further in the article to have the solution to this problem.
