Suspension cracking noise Lexus UX

Check Lexus UX suspension

If you experience a suspension noise when you pass a speed bump on your Lexus UX, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 drive over holes. If it is indeed the cups, think of replacing them quickly or you may damage other parts and have to make more important auto repairs.

Check the cardan shaft

If you are here because you have looked for for “Lexus UX 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 old and the dirt/dust amasses 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 make a turn at low speed. If it cracks in these two circumstances you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Lexus UX, don’t hesitate to read this article.

Check steering hinges/stabilizer bar

Finally, when you detect a suspension noise when your Lexus UX 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 vary direction. If this is your situation, the components that may have been destroyed by regular 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, place it under the car and apply twists on each of its components to check that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Lexus UX 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 Lexus UX, it is possible 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 check by going under your car the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should eliminate the trouble.

Check engine silentblocks

Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Lexus UX. To replace them go to your technician.
