Hearing noises from your car frequently is never comforting, so hearing noises on your Volvo V50 suspensions when you go over a speed bump can be worrying. This sign may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the source and take the necessary actions to resolve the problem, it is with this aim in mind that we wanted to write this content to support 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 Volvo V50
Check Volvo V50 suspension
If you experience a suspension noise when you pass a speed bump on your Volvo V50, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 verify if this is the problem that concerns you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them as soon as possible or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Volvo V50 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on Volvo V50, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volvo V50 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 case, the parts 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 verify it, place it under the automobile and apply twists on each of its elements to verify that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Volvo V50 to your auto technician or replace 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 Volvo V50, 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 cause this squeaking noise. Remember to verify by going under your automobile the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them out from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a pronounced 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 Volvo V50. To swap them go to your technician.
Other speed bump noise Volvo V50
If, even though all its assumptions, you still can’t find the origin of the noise your Volvo V50 makes when you pass a speed bump, we suggest you to read this content on a loud noise on Volvo V50 or to visit your auto technician in order to carry an in-depth check on your Volvo V50 and find this problem.
