Finding out noises from your car frequently is never comforting, so listening noises on your Volkswagen Atlas suspensions when you pass a speed bump can be stressing. This indicator may be a sign of a small issue as well as a warning of a much larger repair to come. In any case, it is necessary to check the source and take the necessary actions to correct the issue, it is with this objective in mind that we wanted to write this article to support 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 Volkswagen Atlas
Check Volkswagen Atlas suspension
If you experience a suspension noise when you pass a speed bump on your Volkswagen Atlas, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the issue that worries you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them as soon as possible 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 searched for “Volkswagen Atlas 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Atlas, don’t hesitate to visit this article.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen Atlas 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 adjust direction. If this is the situation, 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, place it under the automobile and apply twists on each of its elements to check that there is no special 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 technician or change them if they are involved.
squeaky noise speed bump Volkswagen Atlas
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Volkswagen Atlas, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Remember to check by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, 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 issue.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Volkswagen Atlas. To replace them go to your auto technician.
Other speed bump noise Volkswagen Atlas
If, despite all its assumptions, you still can’t locate the origin of the noise your Volkswagen Atlas makes when you pass a speed bump, we advise you to consult this article on a loud noise on Volkswagen Atlas or to visit your technician in order to carry an in-depth check on your Volkswagen Atlas and discover this issue.
