Suspension cracking noise Chevrolet Silverado
Check Chevrolet Silverado suspension
If you notice a suspension noise when you pass a speed bump on your Chevrolet Silverado, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin 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 worries you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them as soon as possible or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Chevrolet Silverado 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their functions is degraded and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two situations you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Chevrolet Silverado 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 change direction. If this is the case, 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 origins 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 special play on one of them, they are supposed to endure you quite strongly over their entire travel. Remember to take your Chevrolet Silverado to your mechanic or replace them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Chevrolet Silverado, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Keep in mind to check by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry 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 process as pads/shock absorbers between the engine and the cradle of the vehicle, a pronounced weakness of these will create 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 Chevrolet Silverado. To swap them go to your auto mechanic.
