Suspension cracking noise Chevrolet Volt
Check Chevrolet Volt suspension
If you notice a suspension noise when you pass a speed bump on your Chevrolet Volt, 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 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 function during small bumps that compress the suspensions. To examine if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them as soon as possible or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Chevrolet Volt 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a noise when they are in torsion. To examine 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 changing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Chevrolet Volt 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 broken 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 examine it, put it under the automobile and apply twists on each of its elements to examine that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto 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 pass a speed bump with your Chevrolet Volt, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Please remember to examine by going under your automobile the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case remove them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks work 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 appears when you pass a speed bumps or any holes with your Chevrolet Volt. To replace them go to your auto technician.
