Suspension cracking noise Cadillac CTS

Check Cadillac CTS suspension

If you experience a suspension noise when you pass a speed bump on your Cadillac CTS, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 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 pass over holes. If it is indeed the cups, think of swapping them quickly or you may ruin other parts and have to make more important maintenance.

Check the cardan shaft

If you are here because you have searched for “Cadillac CTS 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Cadillac CTS, don’t hesitate to visit this article.

Check steering hinges/stabilizer bar

Finally, when you know a suspension noise when your Cadillac CTS 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 modify direction. If this is the case, the parts that may have been destroyed 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 check it, put it under the automobile and apply twists on each of its elements to check that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your Cadillac CTS to your mechanic or replace 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 Cadillac CTS, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Keep in mind to check 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 dry and provoke noise, in which case remove them from the cradle and grease them, this should eliminate the trouble.

Check engine silentblocks

Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a pronounced weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Cadillac CTS. To change them go to your mechanic.
