Suspension cracking noise Bmw Serie 2
Check Bmw Serie 2 suspension
If you experience a suspension noise when you pass a speed bump on your Bmw Serie 2, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check 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 drive over holes. If it is indeed the cups, think of swapping them as soon as possible or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Bmw Serie 2 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their operation is deteriorated and it is possible to experience a sound when they are in torsion.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 circumstances you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Bmw Serie 2 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible.

The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, put it under the automobile and apply twists on each of its elements to check that there is no particular play on one of them, they are supposed 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 pass a speed bump with your Bmw Serie 2, it is possible 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. Keep in mind to check by passing 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 take them off from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will create 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 2. To swap them go to your technician.
