Experiencing noises from your car often is never comforting, so discovering noises on your Ford S-max suspensions when you go over a speed bump can be stressing. This warning sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is important to check the origin and take the necessary actions to correct the problem, it is with this aim in mind that we wanted to write this document to help 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 Ford S-max
Check Ford S-max suspension
If you encounter a suspension noise when you pass a speed bump on your Ford S-max, 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them fairly quickly or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Ford S-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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Ford S-max passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is your situation, the components that may have been damaged 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 examine it, place it under the automobile and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your 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 Ford S-max, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Please remember to examine by going under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a pronounced 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 Ford S-max. To replace them go to your mechanic.
Other speed bump noise Ford S-max
If, even though all its assumptions, you still can’t uncover the source of the noise your Ford S-max makes when you pass a speed bump, we encourage you to consult this article on a loud noise on Ford S-max or to visit your technician in order to carry an in-depth check on your Ford S-max and identify this problem.
