Experiencing noises from your auto often is never comforting, so listening noises on your Bmw 1 series suspensions when you go over a speed bump can be disturbing. This indicator may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to eliminate the problem, it is with this intention in mind that we wanted to write this article to support you see more clearly. We will first see the possible explanations 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 1 series
Check Bmw 1 series suspension
If you notice a suspension noise when you pass a speed bump on your Bmw 1 series, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have searched for “Bmw 1 series 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Bmw 1 series, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Bmw 1 series passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the parts that may have been broken by normal 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 automobile and apply twists on each of its elements to examine 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 vehicle to your auto mechanic or swap 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 go over a speed bump with your Bmw 1 series, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Remember to examine by going under your automobile the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a evident fatigue of these will create 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 1 series. To replace them go to your auto mechanic.
Other speed bump noise Bmw 1 series
If, despite all its assumptions, you still can’t uncover the origin of the noise your Bmw 1 series makes when you pass a speed bump, we suggest you to read this article on a loud noise on Bmw 1 series or to visit your auto mechanic in order to carry an in-depth check on your Bmw 1 series and find this problem.
