Discovering noises from your vehicle frequently is never comforting, so listening noises on your Jeep Grand Cherokee suspensions when you pass a speed bump can be stressful. This sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the origin and take the necessary actions to correct the trouble, it is with this objective in mind that we wanted to write this document to help 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 Jeep Grand Cherokee
Check Jeep Grand Cherokee suspension
If you experience a suspension noise when you pass a speed bump on your Jeep Grand Cherokee, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 trouble that worries you, take a dented road and pay attention to the noise coming from your front axle as you drive 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 looked for for “Jeep Grand Cherokee 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 situations you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Jeep Grand Cherokee, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Jeep Grand Cherokee 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 modify direction. If this is your situation, the parts that may have been affected 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 check it, position it under the car 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. Keep in mind to take your Jeep Grand Cherokee to your auto technician or swap them if they are involved.
squeaky noise speed bump Jeep Grand Cherokee
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Jeep Grand Cherokee, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Please remember to check by going under your car the condition of the paint on your bar which will tell us 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 resolve the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Jeep Grand Cherokee. To replace them go to your mechanic.
