Experiencing noises from your automobile frequently is never reassuring, so hearing noises on your Toyota RAV4 suspensions when you pass a speed bump can be stressing. This sign may be a sign of a insignificant 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 intention in mind that we wanted to write this content to support you see more clearly. We will first see the possible causes for a crack when the speed bump passes, then, 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 Toyota RAV4
Check Toyota RAV4 suspension
If you encounter a suspension noise when you pass a speed bump on your Toyota RAV4, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check 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 ruin other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Toyota RAV4 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Toyota RAV4 passes over a speed bumps, it is possible 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 your situation, the components that may have been broken by normal 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, put it under the vehicle and apply twists on each of its elements to check that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your Toyota RAV4 to your technician or change them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Toyota RAV4, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Bear in mind to check by going under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second plausible 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 fix the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a obvious fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Toyota RAV4. To replace them go to your auto technician.
