Suspension cracking noise Chevrolet Captiva
Check Chevrolet Captiva suspension
If you experience a suspension noise when you pass a speed bump on your Chevrolet Captiva, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 drive 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 researched for “Chevrolet Captiva 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 circumstances you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Chevrolet Captiva passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible.

The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, position 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 expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto technician 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 Captiva, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Please remember to examine by going under your automobile the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case take them off from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced fatigue 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 Captiva. To change them go to your mechanic.
