Listening noises from your automobile often is never comforting, so listening noises on your BMW X6 suspensions when you go over a speed bump can be disturbing. This sign may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the cause and take the necessary actions to correct the trouble, it is with this goal in mind that we wanted to write this document 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 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 BMW X6
Check BMW X6 suspension
If you encounter a suspension noise when you pass a speed bump on your BMW X6, and it is characterized by a “clack” or cracking, it is highly plausible 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 role during small bumps that compress the suspensions. To examine if this is the trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing 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 “BMW X6 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their operation is deteriorated and it is possible to experience a sound when they are in torsion.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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on BMW X6, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your BMW X6 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the components that may have been affected 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 examine it, position it under the vehicle and apply twists on each of its components to examine that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your BMW X6, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Keep in mind to examine by going 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 dry and cause noise, in which case take them out from the cradle and grease them, this should eliminate the trouble.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a obvious fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your BMW X6. To swap them go to your technician.
Other speed bump noise BMW X6
If, even though all its assumptions, you still can’t locate the origin of the noise your BMW X6 makes when you pass a speed bump, we advise you to read this content on a loud noise on BMW X6 or to visit your mechanic in order to carry an in-depth check on your BMW X6 and identify this trouble.
