Suspension cracking noise Chevrolet Malibu
Check Chevrolet Malibu suspension
If you notice a suspension noise when you pass a speed bump on your Chevrolet Malibu, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, 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 job during small bumps that compress the suspensions. To check if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them quickly 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 looked for for “Chevrolet Malibu 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Chevrolet Malibu, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Chevrolet Malibu passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, 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 causes of your noises, to check it, position it under the car and apply twists on each of its components 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 Chevrolet Malibu to your technician 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 pass a speed bump with your Chevrolet Malibu, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Remember to check by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last point 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 automobile, a noticable weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Chevrolet Malibu. To change them go to your mechanic.
