Discovering noises from your auto frequently is never reassuring, so hearing noises on your Bmw Serie 1 suspensions when you pass a speed bump can be disturbing. This indicator may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. In any case, it is essential to check the cause and take the necessary actions to resolve the trouble, it is with this goal in mind that we wanted to write this content 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 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 Serie 1
Check Bmw Serie 1 suspension
If you experience a suspension noise when you pass a speed bump on your Bmw Serie 1, and it is categorized by a “clack” or cracking, it is highly plausible 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 role during small bumps that compress the suspensions. To verify if this is the trouble that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them fairly quickly or you may damage other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Bmw Serie 1 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 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 make a turn at low speed. If it cracks in these two cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Bmw Serie 1, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Bmw Serie 1 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is the case, the parts that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, position 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 resist you quite strongly over their entire travel. Keep in mind to take your Bmw Serie 1 to your auto technician or replace 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 Serie 1, it is plausible 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 verify by passing under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them out from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a evident weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Bmw Serie 1. To replace them go to your auto technician.
Other speed bump noise Bmw Serie 1
If, even though all its assumptions, you still can’t locate the origin of the noise your Bmw Serie 1 makes when you pass a speed bump, we encourage you to refer to this article on a loud noise on Bmw Serie 1 or to visit your auto technician in order to carry an in-depth check on your Bmw Serie 1 and discover this trouble.
