Check Bmw Serie 4 F32 suspension
If you encounter a suspension noise when you pass a speed bump on your Bmw Serie 4 F32, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 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 pass over holes. If it is indeed the cups, think of changing them quickly or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Bmw Serie 4 F32 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a sound when they are in torsion.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 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 circumstances you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Bmw Serie 4 F32 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you vary direction. If this is your situation, the parts 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 causes of your noises, to examine it, put it under the automobile and apply twists on each of its components to examine that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel.

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 Serie 4 F32, 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 create this squeaking noise. Bear in mind to examine by going under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them out from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a pronounced weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Bmw Serie 4 F32. To swap them go to your auto technician.
