Suspension cracking noise saab 9 3
Check saab 9 3 suspension
If you experience a suspension noise when you pass a speed bump on your saab 9 3, 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 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 check if this is the trouble that worries 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 swapping them fairly quickly or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “saab 9 3 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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. If you have the feeling that this noise is more like a a loud noise on saab 9 3, don’t hesitate to read this content.

Check the stabilizer bar

Second possible explanation, 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 eliminate the trouble.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the automobile, a evident fatigue of these will create 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 saab 9 3.
