Finding out noises from your auto often is never comforting, so listening noises on your Buick Cascada suspensions when you go over a speed bump can be stressing. This indicator may be a sign of a minor issue as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to solve the issue, it is with this intention in mind that we wanted to write this article to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, what can be the reason of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Buick Cascada
Check Buick Cascada suspension
If you encounter a suspension noise when you pass a speed bump on your Buick Cascada, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and focus on 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 damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Buick Cascada suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get old and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a noise when they are in torsion. To examine 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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on Buick Cascada, don’t hesitate to refer to this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Buick Cascada passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is your situation, the components that may have been affected by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to examine it, place it under the automobile and apply twists on each of its elements to examine that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Buick Cascada to your auto technician or change them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Buick Cascada, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Bear in mind to examine by passing under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them out from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Buick Cascada. To replace them go to your mechanic.
Other speed bump noise Buick Cascada
If, even though all its assumptions, you still can’t find the origin of the noise your Buick Cascada makes when you pass a speed bump, we encourage you to read this content on a loud noise on Buick Cascada or to visit your auto technician in order to carry an in-depth check on your Buick Cascada and find this issue.
