Suspension cracking noise Chevrolet Sonic

Check Chevrolet Sonic suspension

If you notice a suspension noise when you pass a speed bump on your Chevrolet Sonic, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 verify if this is the trouble 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 changing 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 “Chevrolet Sonic 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion. To verify 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 conditions you should consider changing it or them.

Check steering hinges/stabilizer bar

Finally, when you recognise a suspension noise when your Chevrolet Sonic passes over a speed bumps, it is possible 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 your situation, the parts that may have been damaged 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 verify it, put it under the automobile and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto technician 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 go over a speed bump with your Chevrolet Sonic, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Bear in mind to verify by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, 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 solve the trouble.

Check engine silentblocks

Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a pronounced weakness of these will generate 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 Sonic. To swap them go to your technician.
