Experiencing noises from your vehicle frequently is never reassuring, so discovering noises on your Bmw Serie 6 suspensions when you pass a speed bump can be worrying. This indicator may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to resolve the problem, it is with this objective in mind that we wanted to write this content to help you see more clearly. We will first see the possible reasons 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 Serie 6
Check Bmw Serie 6 suspension
If you experience a suspension noise when you pass a speed bump on your Bmw Serie 6, 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them quickly 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 6 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 old and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a noise 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 recognise a suspension noise when your Bmw Serie 6 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 modify direction. If this is the case, the parts that may have been damaged by usual 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, place it under the car and apply twists on each of its components to examine 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 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 pass a speed bump with your Bmw Serie 6, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Remember to examine by passing under your car 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 provoke 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 examine together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, 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 occurs when you pass a speed bumps or any holes with your Bmw Serie 6. To replace them go to your mechanic.
Other speed bump noise Bmw Serie 6
If, despite all its assumptions, you still can’t locate the origin of the noise your Bmw Serie 6 makes when you pass a speed bump, we advise you to consult this article on a loud noise on Bmw Serie 6 or to visit your mechanic in order to carry an in-depth check on your Bmw Serie 6 and find this problem.
