Suspension cracking noise Lexus CT
Check Lexus CT suspension
If you notice a suspension noise when you pass a speed bump on your Lexus CT, 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 old, 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 problem that concerns 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 changing them as soon as possible 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 looked for for “Lexus CT 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 circumstances you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Lexus CT passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is your situation, 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 causes of your noises, to check it, position it under the car and apply twists on each of its elements to check that there is no particular play on one of them, they are expected 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 Lexus CT, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Please remember to check by passing under your car the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them off from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a obvious fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Lexus CT. To change them go to your technician.
