Suspension cracking noise Bmw Serie 3 E93
Check Bmw Serie 3 E93 suspension
If you experience a suspension noise when you pass a speed bump on your Bmw Serie 3 E93, and it is characterized 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 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 verify if this is the problem 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 swapping them as soon as possible or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Bmw Serie 3 E93 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 situations you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Bmw Serie 3 E93 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the components that may have been affected by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, place it under the car 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. Remember to take your vehicle to your mechanic 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 go over a speed bump with your Bmw Serie 3 E93, 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 create this squeaking noise. Please remember to verify by going under your car 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 dry and create noise, in which case disassemble them from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Bmw Serie 3 E93. To change them go to your auto mechanic.
