Hearing noises from your car often is never comforting, so hearing noises on your BMW X1 suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. In any case, it is necessary to check the source and take the necessary actions to resolve the trouble, it is with this intention in mind that we wanted to write this content to support 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 BMW X1
Check BMW X1 suspension
If you experience a suspension noise when you pass a speed bump on your BMW X1, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 verify if this is the trouble that concerns you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “BMW X1 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a sound when they are in torsion.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 X1, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your BMW X1 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 destroyed by normal 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, put it under the car and apply twists on each of its elements to verify that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your BMW X1 to your mechanic 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 BMW X1, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Bear in mind to verify by passing under your car the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should solve the trouble.
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 car, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your BMW X1. To change them go to your auto mechanic.
Other speed bump noise BMW X1
If, even though all its assumptions, you still can’t find the source of the noise your BMW X1 makes when you pass a speed bump, we recommend you to read this content on a loud noise on BMW X1 or to visit your mechanic in order to carry an in-depth check on your BMW X1 and find this trouble.
