Experiencing noises from your vehicle often is never reassuring, so hearing noises on your Toyota Land Cruiser Serie 150 suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the origin and take the necessary actions to resolve the problem, it is with this objective 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, 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 Land Cruiser Serie 150
Check Toyota Land Cruiser Serie 150 suspension
If you notice a suspension noise when you pass a speed bump on your Toyota Land Cruiser Serie 150, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 concerns 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 swapping them fairly quickly or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Toyota Land Cruiser Serie 150 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two situations you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Land Cruiser Serie 150, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Toyota Land Cruiser Serie 150 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary 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 origins 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 expected to endure you quite strongly over their entire travel. Keep in mind to take your Toyota Land Cruiser Serie 150 to your auto mechanic 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 go over a speed bump with your Toyota Land Cruiser Serie 150, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can cause 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 disassemble them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your Toyota Land Cruiser Serie 150. To replace them go to your auto mechanic.
