Hearing noises from your automobile often is never reassuring, so listening noises on your Dacia Sandero suspensions when you go over a speed bump can be stressful. This symptom may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is important to check the cause and take the necessary actions to correct the trouble, 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 explanations 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 Dacia Sandero
Check Dacia Sandero suspension
If you experience a suspension noise when you pass a speed bump on your Dacia Sandero, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, 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 function during small bumps that compress the suspensions. To check if this is the trouble that concerns you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them quickly or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Dacia Sandero 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is degraded and it is possible to experience a sound when they are in torsion. To check 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 situations you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Dacia Sandero passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change 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 origins of your noises, to check it, place it under the vehicle and apply twists on each of its elements to check 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 vehicle to your mechanic or replace them if they are involved.
squeaky noise speed bump Dacia Sandero
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 Dacia Sandero, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Bear in mind to check by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your Dacia Sandero. To change them go to your mechanic.
