Experiencing noises from your auto often is never comforting, so listening noises on your Ford C-max suspensions when you pass a speed bump can be worrying. This warning sign may be a sign of a minor problem as well as a warning of a much larger repair to come. In any case, it is important to check the cause and take the necessary actions to eliminate the problem, it is with this aim in mind that we wanted to write this article to help 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 Ford C-max
Check Ford C-max suspension
If you notice a suspension noise when you pass a speed bump on your Ford C-max, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, 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 job during small bumps that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate 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 fixes.
Check the cardan shaft
If you are here because you have looked for for “Ford C-max 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 make a 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 Ford C-max, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Ford C-max 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 case, the components that may have been broken 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 verify it, place it under the automobile and apply twists on each of its elements to verify that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your vehicle to your technician or change them if they are involved.

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 Ford C-max, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Bear in mind 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 dried out and bring on noise, in which case remove them from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a pronounced fatigue of these will create 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 Ford C-max. To change them go to your mechanic.
Other speed bump noise Ford C-max
If, even though all its assumptions, you still can’t uncover the origin of the noise your Ford C-max makes when you pass a speed bump, we advise you to read this article on a loud noise on Ford C-max or to visit your technician in order to carry an in-depth check on your Ford C-max and find this problem.
