Finding out noises from your car frequently is never comforting, so listening noises on your Jeep Liberty suspensions when you pass a speed bump can be stressful. This indicator may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to resolve the problem, 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 Liberty
Check Jeep Liberty suspension
If you experience a suspension noise when you pass a speed bump on your Jeep Liberty, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are old, 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 problem that concerns you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping them as soon as possible or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Jeep Liberty 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 old 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 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Jeep Liberty, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Jeep Liberty 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 affected by regular 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 vehicle 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. Keep in mind to take your Jeep Liberty to your mechanic or change them if they are involved.

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 Liberty, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Bear in mind 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 dry and create noise, in which case remove them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a noticable 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 Jeep Liberty. To swap them go to your mechanic.
