Experiencing noises from your auto often is never comforting, so hearing noises on your Opel Vivaro suspensions when you go over a speed bump can be stressful. 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 fundamental to check the cause and take the necessary actions to correct the issue, it is with this goal in mind that we wanted to write this article to help you see more clearly. We will first see the possible causes for a crack when the speed bump passes, then, 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 Opel Vivaro
Check Opel Vivaro suspension
If you encounter a suspension noise when you pass a speed bump on your Opel Vivaro, and it is characterized by a “clack” or cracking, it is highly possible 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 drive over holes. If it is indeed the cups, think of changing them quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Opel Vivaro 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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 cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Opel Vivaro, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Opel Vivaro passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just 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 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 automobile and apply twists on each of its components to examine 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 Opel Vivaro to your 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 Opel Vivaro, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Keep in mind to examine by going under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case disassemble them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Opel Vivaro. To replace them go to your mechanic.
Other speed bump noise Opel Vivaro
If, despite all its assumptions, you still can’t find the origin of the noise your Opel Vivaro makes when you pass a speed bump, we encourage you to consult this article on a loud noise on Opel Vivaro or to visit your technician in order to carry an in-depth check on your Opel Vivaro and discover this issue.
