Finding out noises from your automobile often is never reassuring, so hearing noises on your BMW X5 suspensions when you pass a speed bump can be stressful. This warning sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. In any case, it is fundamental to check the origin and take the necessary actions to eliminate the issue, 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, 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 X5
Check BMW X5 suspension
If you experience a suspension noise when you pass a speed bump on your BMW X5, 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 dead, 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 issue that concerns 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 researched for “BMW X5 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 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 X5, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your BMW X5 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify 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 verify it, place it under the vehicle and apply twists on each of its components to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your BMW X5 to your technician or change them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your BMW X5, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Remember to verify by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them off from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your BMW X5. To replace them go to your auto technician.
Other speed bump noise BMW X5
If, even though all its assumptions, you still can’t locate the origin of the noise your BMW X5 makes when you pass a speed bump, we encourage you to read this content on a loud noise on BMW X5 or to visit your technician in order to carry an in-depth check on your BMW X5 and determine this issue.
