Suspension cracking noise Chevrolet City Express

Check Chevrolet City Express suspension

If you encounter a suspension noise when you pass a speed bump on your Chevrolet City Express, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, 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 job during small bumps that compress the suspensions. To verify if this is the problem that worries you, take a dented road and focus on the noise coming from your front axle as you go 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 maintenance.

Check the cardan shaft

If you are here because you have looked for for “Chevrolet City Express 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Chevrolet City Express, don’t hesitate to read this document.

Check steering hinges/stabilizer bar

Finally, when you recognise a suspension noise when your Chevrolet City Express passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the parts that may have been affected by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, position it under the vehicle and apply twists on each of its components to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto mechanic or change 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 City Express, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Please remember to verify by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them off from the cradle and grease them, this should resolve the problem.

Check engine silentblocks

Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue 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 City Express. To replace them go to your mechanic.
