Listening noises from your car frequently is never reassuring, so listening noises on your Opel Corsa suspensions when you pass a speed bump can be worrying. This warning sign may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the cause and take the necessary actions to resolve the issue, it is with this intention in mind that we wanted to write this document to support you see more clearly. We will first see the possible causes for a crack when the speed bump passes, after that, what can be the cause 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 Opel Corsa
Check Opel Corsa suspension
If you notice a suspension noise when you pass a speed bump on your Opel Corsa, 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 old, 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 examine if this is the issue that concerns you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them fairly quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Opel Corsa 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Opel Corsa, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Opel Corsa 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 adjust direction. If this is the situation, the parts that may have been broken by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, position it under the vehicle and apply twists on each of its elements to examine that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or change them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Opel Corsa, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Remember to examine by passing under your vehicle the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a evident weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Opel Corsa. To change them go to your mechanic.
