Hearing noises from your auto often is never reassuring, so listening noises on your Buick Enclave suspensions when you go over a speed bump can be disturbing. This symptom may be a sign of a minor 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 solve the issue, it is with this aim in mind that we wanted to write this content to support you see more clearly. We will first see the possible explanations 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 Buick Enclave
Check Buick Enclave suspension
If you experience a suspension noise when you pass a speed bump on your Buick Enclave, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the issue that concerns 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 changing them fairly quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Buick Enclave 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Buick Enclave, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Buick Enclave 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 your situation, the components that may have been broken by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to check it, position it under the vehicle and apply twists on each of its elements to check that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or replace 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 Buick Enclave, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Remember to check by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them out from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a evident fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Buick Enclave. To replace them go to your mechanic.
Other speed bump noise Buick Enclave
If, even though all its assumptions, you still can’t uncover the origin of the noise your Buick Enclave makes when you pass a speed bump, we advise you to consult this content on a loud noise on Buick Enclave or to visit your auto technician in order to carry an in-depth check on your Buick Enclave and find this issue.
