Discovering noises from your automobile regularly is never reassuring, so hearing noises on your Opel Mokka suspensions when you pass a speed bump can be worrying. This symptom may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. In any case, it is important to check the source and take the necessary actions to correct the trouble, it is with this goal in mind that we wanted to write this document to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, 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 Opel Mokka
Check Opel Mokka suspension
If you experience a suspension noise when you pass a speed bump on your Opel Mokka, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are dead, 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 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 circulate over holes. If it is indeed the cups, think of swapping them quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Opel Mokka 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 action 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 situations you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Opel Mokka, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Opel Mokka passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the components that may have been damaged by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, position it under the car and apply twists on each of its elements to check that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your Opel Mokka to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Opel Mokka
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Opel Mokka, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Please remember to check by passing under your car the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case disassemble them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Opel Mokka. To change them go to your mechanic.
Other speed bump noise Opel Mokka
If, even though all its assumptions, you still can’t find the origin of the noise your Opel Mokka makes when you pass a speed bump, we recommend you to read this article on a loud noise on Opel Mokka or to visit your auto mechanic in order to carry an in-depth check on your Opel Mokka and discover this trouble.
