Experiencing noises from your auto regularly is never comforting, so discovering noises on your Toyota Sequoia suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to eliminate the issue, it is with this aim in mind that we wanted to write this content to help you see more clearly. We will first see the possible reasons 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 Sequoia
Check Toyota Sequoia suspension
If you encounter a suspension noise when you pass a speed bump on your Toyota Sequoia, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 concerns 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 damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Toyota Sequoia 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 situations you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Toyota Sequoia 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 adjust direction. If this is your situation, the parts that may have been broken by usual 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 vehicle and apply twists on each of its components to examine that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic or swap 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 Sequoia, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Keep in mind to examine by passing under your vehicle the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them off from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Toyota Sequoia. To swap them go to your technician.
Other speed bump noise Toyota Sequoia
If, even though all its assumptions, you still can’t locate the origin of the noise your Toyota Sequoia makes when you pass a speed bump, we recommend you to read this content on a loud noise on Toyota Sequoia or to visit your auto mechanic in order to carry an in-depth check on your Toyota Sequoia and find this issue.
