Finding out noises from your automobile regularly is never reassuring, so discovering noises on your Subaru Outback suspensions when you go over a speed bump can be stressful. This symptom 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 necessary to check the source and take the necessary actions to resolve the problem, it is with this objective in mind that we wanted to write this article to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, what can be the reason 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 Outback
Check Subaru Outback suspension
If you encounter a suspension noise when you pass a speed bump on your Subaru Outback, 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 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 job during small bumps that compress the suspensions. To check if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them fairly quickly or you may damage other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have searched for “Subaru Outback 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 situations you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Subaru Outback passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the components that may have been broken by regular 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, place 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 meant to endure you quite strongly over their entire travel. Remember to take your Subaru Outback to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Subaru Outback
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Subaru Outback, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Bear in mind to check by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them off from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a noticable weakness of these will make 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 Outback. To change them go to your technician.
Other speed bump noise Subaru Outback
If, despite all its assumptions, you still can’t find the source of the noise your Subaru Outback makes when you pass a speed bump, we recommend you to read this content on a loud noise on Subaru Outback or to visit your auto mechanic in order to carry an in-depth check on your Subaru Outback and determine this problem.
