Hearing noises from your vehicle frequently is never comforting, so discovering noises on your Toyota Tacoma suspensions when you pass a speed bump can be stressing. This warning sign may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the cause and take the necessary actions to resolve the trouble, it is with this intention 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 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-noise-toyota-tacoma

Suspension cracking noise Toyota Tacoma

Check Toyota Tacoma suspension

If you encounter a suspension noise when you pass a speed bump on your Toyota Tacoma, and it is characterized 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the trouble that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them quickly or you may damage other parts and have to make more important maintenance.

Check the cardan shaft

If you are here because you have looked for for “Toyota Tacoma 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their functions is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two situations you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Tacoma, don’t hesitate to read this document.

Check steering hinges/stabilizer bar

Finally, when you know a suspension noise when your Toyota Tacoma 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 change direction. If this is your situation, the components that may have been affected by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, put it under the car and apply twists on each of its components to verify that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your vehicle to your auto technician or swap them if they are involved.

squeaky noise speed bump Toyota Tacoma

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 Tacoma, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Remember to verify by going under your car the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should fix the trouble.

Check engine silentblocks

Finally, last possibility that we can verify together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable weakness 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 Tacoma. To replace them go to your technician.
