We will first see the possible reasons for a crack when the speed bump passes, after that, 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 Hilux 3
Check Toyota Hilux 3 suspension
If you notice a suspension noise when you pass a speed bump on your Toyota Hilux 3, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 examine if this is the issue that worries you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them fairly quickly or you may ruin other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Toyota Hilux 3 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a sound when they are in torsion. To examine 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 swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Toyota Hilux 3 passes over a speed bumps, it is imaginable 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 the situation, the components that may have been affected 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 examine it, place it under the car and apply twists on each of its elements to examine that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto mechanic or change them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Toyota Hilux 3, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Keep in mind to examine by passing under your car the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case remove them from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, 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 comes up when you pass a speed bumps or any holes with your Toyota Hilux 3. To replace them go to your mechanic.
