Verify the suspension
If you experience a clicking noise on your Alfa Romeo Giulietta each time you pass a speed bump, it is extremely conceivable that your suspension block is the cause of the noise. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To examine if this is the issue that worries you, take a dented road and, at low speed, listen to the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them soon as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Alfa Romeo Giulietta at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a cause. To examine the state of the spring, place the car 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 examine between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you observe a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, make 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 consider changing it or them.
