Listening noises from your vehicle regularly is never reassuring, so listening noises on your Volvo S90 suspensions when you pass a speed bump can be worrying. This sign may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. In any case, it is necessary to check the cause and take the necessary actions to correct the trouble, it is with this intention in mind that we wanted to write this article to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, 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 Volvo S90
Check Volvo S90 suspension
If you notice a suspension noise when you pass a speed bump on your Volvo S90, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 trouble that worries 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 replacing them fairly quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Volvo S90 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Volvo S90, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Volvo S90 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the components that may have been broken by normal 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, put 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. Please remember to take your vehicle to your technician or swap them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Volvo S90, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can create 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 plausible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case disassemble them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the vehicle, a evident fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Volvo S90. To swap them go to your mechanic.
Other speed bump noise Volvo S90
If, despite all its assumptions, you still can’t uncover the source of the noise your Volvo S90 makes when you pass a speed bump, we suggest you to read this article on a loud noise on Volvo S90 or to visit your technician in order to carry an in-depth check on your Volvo S90 and discover this trouble.
