Experiencing noises from your auto frequently is never reassuring, so discovering noises on your Toyota FJ Cruiser suspensions when you go over 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. Whatever the case, it is essential to check the origin and take the necessary actions to eliminate the issue, it is with this objective in mind that we wanted to write this article to help you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, 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 Toyota FJ Cruiser
Check Toyota FJ Cruiser suspension
If you encounter a suspension noise when you pass a speed bump on your Toyota FJ Cruiser, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the issue that concerns 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 changing them fairly quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Toyota FJ Cruiser 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 operation 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Toyota FJ Cruiser, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Toyota FJ Cruiser passes over a speed bumps, it is possible 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 situation, the components that may have been destroyed by regular 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, put it under the automobile and apply twists on each of its elements to check that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your Toyota FJ Cruiser to your technician or change 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 Toyota FJ Cruiser, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Remember to check by passing under your automobile 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 dried out and create noise, in which case disassemble them from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last possibility 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 auto, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Toyota FJ Cruiser. To swap them go to your mechanic.
