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 create 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, pay attention to the sound coming from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.

To check the shape 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 identical on each side (empty car for measurement). You can also check between the front and rear, if there is a gap too large it denotes 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.
