Experiencing noises from your vehicle regularly is never reassuring, so discovering noises on your Citroen Saxo suspensions when you pass a speed bump can be stressing. This symptom may be a sign of a small trouble as well as a warning of a much larger repair to come. In any case, it is essential to check the cause and take the necessary actions to solve the trouble, it is with this objective in mind that we wanted to write this document 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 Citroen Saxo
Check Citroen Saxo suspension
If you experience a suspension noise when you pass a speed bump on your Citroen Saxo, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 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 as soon as possible or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Citroen Saxo 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 old and the dirt/dust builds up inside them their functions is deteriorated 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 turn at low speed. If it cracks in these two circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Citroen Saxo, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Citroen Saxo passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the components that may have been destroyed by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, position it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Citroen Saxo
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 Citroen Saxo, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Keep in mind to verify by going under your car 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 dried out and cause noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Citroen Saxo. To change them go to your technician.
Other speed bump noise Citroen Saxo
If, despite all its assumptions, you still can’t find the origin of the noise your Citroen Saxo makes when you pass a speed bump, we advise you to read this article on a loud noise on Citroen Saxo or to visit your auto mechanic in order to carry an in-depth check on your Citroen Saxo and identify this trouble.
