Finding out noises from your auto regularly is never reassuring, so hearing noises on your Subaru Crosstrek suspensions when you pass a speed bump can be stressing. This sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. In any case, it is fundamental to check the source and take the necessary actions to solve the issue, it is with this goal in mind that we wanted to write this document to help you see more clearly. We will first see the possible causes for a crack when the speed bump passes, after that, what can be the cause of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Subaru Crosstrek
Check Subaru Crosstrek suspension
If you encounter a suspension noise when you pass a speed bump on your Subaru Crosstrek, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To check if this is the issue 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 replacing them as soon as possible or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Subaru Crosstrek 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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 replacing it or them. If you have the feeling that this noise is more like a a loud noise on Subaru Crosstrek, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Subaru Crosstrek passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the components that may have been damaged 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 automobile and apply twists on each of its components to check that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your technician or swap them if they are involved.
squeaky noise speed bump Subaru Crosstrek
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 Subaru Crosstrek, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Bear in mind to check by going under your automobile the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, 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 solve the issue.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Subaru Crosstrek. To change them go to your auto technician.
Other speed bump noise Subaru Crosstrek
If, even though all its assumptions, you still can’t uncover the source of the noise your Subaru Crosstrek makes when you pass a speed bump, we suggest you to read this content on a loud noise on Subaru Crosstrek or to visit your technician in order to carry an in-depth check on your Subaru Crosstrek and determine this issue.
