Discovering noises from your vehicle frequently is never reassuring, so discovering noises on your Subaru Impreza suspensions when you pass a speed bump can be disturbing. This sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the source and take the necessary actions to solve the problem, it is with this intention in mind that we wanted to write this content to help you see more clearly. We will first see the possible explanations 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 Impreza
Check Subaru Impreza suspension
If you experience a suspension noise when you pass a speed bump on your Subaru Impreza, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 function during small bumps that compress the suspensions. To check if this is the problem 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 replacing them fairly quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Subaru Impreza 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 conditions you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Subaru Impreza 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 change direction. If this is your situation, the components that may have been destroyed by normal 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 vehicle and apply twists on each of its components to check that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Please remember to take your vehicle to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Subaru Impreza
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 Impreza, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Bear in mind to check by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible 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 point that we can check together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the vehicle, 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 shows up when you pass a speed bumps or any holes with your Subaru Impreza. To change them go to your mechanic.
Other speed bump noise Subaru Impreza
If, despite all its assumptions, you still can’t find the origin of the noise your Subaru Impreza makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Subaru Impreza or to visit your auto mechanic in order to carry an in-depth check on your Subaru Impreza and identify this problem.
