Experiencing noises from your car regularly is never comforting, so hearing noises on your Subaru Forester suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a small problem as well as a warning of a much larger repair to come. In any case, it is important to check the origin and take the necessary actions to correct the problem, it is with this aim 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 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 Forester
Check Subaru Forester suspension
If you notice a suspension noise when you pass a speed bump on your Subaru Forester, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, 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 verify if this is the problem that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them as soon as possible or you may damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Subaru Forester 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 accumulates inside them their functions is degraded and it is possible to experience a noise when they are in torsion. To verify 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 turn at low speed. If it cracks in these two cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Subaru Forester, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Subaru Forester 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 the situation, the parts that may have been affected by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, place it under the car and apply twists on each of its components to verify that there is no special 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.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Subaru Forester, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Keep in mind to verify by passing under your car the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them out from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness 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 Subaru Forester. To change them go to your auto technician.
