Suspension cracking noise Cadillac ATS
Check Cadillac ATS suspension
If you experience a suspension noise when you pass a speed bump on your Cadillac ATS, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are dead, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify if this is the trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of changing them quickly or you may ruin other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Cadillac ATS suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a sound when they are in torsion. To verify this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to make a turn at low speed. If it cracks in these two conditions you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Cadillac ATS passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is the situation, the parts that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, put it under the vehicle and apply twists on each of its components to verify that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Keep in mind to take your Cadillac ATS to your auto technician or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Cadillac ATS, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Keep in mind to verify by going under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them out from the cradle and grease them, this should eliminate the trouble.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Cadillac ATS. To change them go to your auto technician.
