We will first see the possible explanations 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 Serie 1 F20
Check Bmw Serie 1 F20 suspension
If you experience a suspension noise when you pass a speed bump on your Bmw Serie 1 F20, and it is characterized 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 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 job during small bumps that compress the suspensions. To check if this is the trouble that concerns you, take a dented road and focus on the noise coming from your front axle as you go 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 Serie 1 F20 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion. To check 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 conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Bmw Serie 1 F20, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Bmw Serie 1 F20 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the parts that may have been broken 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 check it, position it under the vehicle and apply twists on each of its components to check that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto technician or change 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 Serie 1 F20, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Please remember to check by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks operate 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 happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Bmw Serie 1 F20. To change them go to your mechanic.
Other speed bump noise Bmw Serie 1 F20
