Hearing noises from your vehicle frequently is never comforting, so listening noises on your Mercedes Gla suspensions when you go over a speed bump can be stressing. This warning sign may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the cause and take the necessary actions to resolve the problem, it is with this goal in mind that we wanted to write this article to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, 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 Mercedes Gla
Check Mercedes Gla suspension
If you experience a suspension noise when you pass a speed bump on your Mercedes Gla, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 examine if this is the problem that worries you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them fairly 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 searched for “Mercedes Gla 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Mercedes Gla, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Mercedes Gla passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the components that may have been destroyed 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, put it under the automobile and apply twists on each of its components to examine that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto mechanic or swap 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 go over a speed bump with your Mercedes Gla, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Remember to examine by passing under your automobile the condition of the paint on your bar which will show if there is friction. Second possible 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 problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Mercedes Gla. To change them go to your mechanic.
