Experiencing noises from your car regularly is never comforting, so listening noises on your Opel Grandland X suspensions when you go over a speed bump can be stressful. This sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is necessary to check the cause and take the necessary actions to correct the problem, it is with this goal in mind that we wanted to write this document to support you see more clearly. We will first see the possible causes 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 Grandland X
Check Opel Grandland X suspension
If you notice a suspension noise when you pass a speed bump on your Opel Grandland X, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine 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 circulate over holes. If it is indeed the cups, think of replacing them fairly 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 searched for “Opel Grandland X 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Opel Grandland X, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Opel Grandland X passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is the situation, 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, position 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. Please remember to take your vehicle to your mechanic or change them if they are involved.
squeaky noise speed bump Opel Grandland X
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 Opel Grandland X, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Bear in mind 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 create noise, in which case disassemble them from the cradle and grease them, this should fix 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 car, a obvious weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Opel Grandland X. To replace them go to your technician.
Other speed bump noise Opel Grandland X
If, despite all its assumptions, you still can’t find the origin of the noise your Opel Grandland X makes when you pass a speed bump, we advise you to refer to this content on a loud noise on Opel Grandland X or to visit your mechanic in order to carry an in-depth check on your Opel Grandland X and determine this problem.
