Verify the suspension
If you experience a clicking noise on your Buick LaCrosse each time you pass a speed bump, it is extremely possible that your suspension block is the cause of the sound.

To verify if this is the problem that concerns 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

To verify the condition of the spring, place the vehicle 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 verify between the front and rear, if there is a gap too significant 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.
