Listening noises from your vehicle frequently is never comforting, so hearing noises on your BMW X3 suspensions when you pass a speed bump can be stressing. This indicator may be a sign of a minor issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the cause and take the necessary actions to resolve the issue, it is with this objective in mind that we wanted to write this content to help you see more clearly. We will first see the possible reasons 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 BMW X3
Check BMW X3 suspension
If you notice a suspension noise when you pass a speed bump on your BMW X3, 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 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 issue that worries you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them fairly quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “BMW X3 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 amasses inside them their functions is degraded and it is possible to experience a noise 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 conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on BMW X3, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your BMW X3 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the parts 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 check it, put it under the automobile and apply twists on each of its elements to check that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your BMW X3 to your auto mechanic or replace 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 BMW X3, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Please remember to check by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case remove them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a evident weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your BMW X3. To replace them go to your auto mechanic.
Other speed bump noise BMW X3
If, even though all its assumptions, you still can’t locate the origin of the noise your BMW X3 makes when you pass a speed bump, we advise you to refer to this content on a loud noise on BMW X3 or to visit your auto mechanic in order to carry an in-depth check on your BMW X3 and find this issue.
