Examine the suspension
If you encounter a clicking noise on your Chevrolet Express each time you pass a speed bump, it is extremely conceivable 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, focus on 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
If you notice a clicking noise on your Chevrolet Express at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a explanation. To examine the shape of the spring, position the automobile 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 significant 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, 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 consider replacing it or them.
