Listening noises from your vehicle frequently is never reassuring, so discovering noises on your Toyota Hilux suspensions when you go over a speed bump can be stressing. This warning sign may be a sign of a insignificant trouble 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 eliminate the trouble, it is with this goal in mind that we wanted to write this content 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 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 Hilux
Check Toyota Hilux suspension
If you experience a suspension noise when you pass a speed bump on your Toyota Hilux, 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 verify if this is the trouble that worries you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them 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 Hilux 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Hilux, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Toyota Hilux passes over a speed bumps, it is possible 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 causes of your noises, to verify it, put it under the automobile and apply twists on each of its components to verify that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your mechanic or change them if they are involved.
squeaky noise speed bump Toyota Hilux
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 Hilux, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Bear in mind to verify by passing under your automobile the condition of the paint on your bar which will indicate 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 out from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable fatigue of these will create 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 Hilux. To change them go to your mechanic.
