Hearing noises from your vehicle regularly is never comforting, so listening noises on your Opel Agila suspensions when you go over 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. Whatever the case, it is essential to check the cause and take the necessary actions to eliminate the trouble, it is with this goal 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, after that, what can be the reason 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 Agila
Check Opel Agila suspension
If you notice a suspension noise when you pass a speed bump on your Opel Agila, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 verify 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 pass 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 vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Opel Agila 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their operation is deteriorated and it is possible to experience a noise when they are in torsion.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 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 Agila, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Opel Agila passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you vary 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 causes of your noises, to verify it, position it under the car and apply twists on each of its elements to verify that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Opel Agila to your auto technician or change them if they are involved.
squeaky noise speed bump Opel Agila
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Opel Agila, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Keep in mind to verify by going 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 dry and bring on noise, in which case take them off from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable fatigue of these will make 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 Agila. To change them go to your mechanic.
