Being subject to recurring noise on your vehicle tends to be annoying, a vehicle is so sophisticated that it is usually difficult to locate its origin and even more so to find the part that causes it. If you have already experienced a clicking noise on your Toyota Aygo, we will probably be able to help you. Indeed, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Toyota Aygo. This is why, firstly, we will look at what are the reasons of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the sources of clicking noise on Toyota Aygo coming from your suspensions.
I notice a clicking noise on Toyota Aygo located on my engine
Verify your high engine
If you notice a clicking noise on Toyota Aygo, and this noise is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two parts can be the triggers of these ticking noises on Toyota Aygo. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this circumstance, remember to change them.
Verify your low engine
If you have distinguished the spot of origin of the Toyota Aygo clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, the risk in the long term is the breakage of the motor. These two maintenance are very complex and most mechanics will suggest you to replace the engine of your Toyota Aygo.
Combustion problem
Finally, if you have the feeling that this clicking noise on Toyota Aygo is linked to the combustion of your engine, there are three possible origins of it. Verify the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible that your timing belt is shifted and that it does not properly manage the timing of the various engine elements to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are injured. In this circumstance, do not hesitate to check this document which deals in detail with the different injection sounds on Toyota Aygo.
I notice a clicking noise on Toyota Aygo in my direction
Verify the state of the gimbals
One of the most common reasons of a clicking noises in the direction of your Toyota Aygo is linked with the direction of the vehicle. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can create a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will harm the cardan shaft very quickly and must be changed rapidly, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it. If you would like more detailed information about gimbals noises on Toyota Aygo, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you experience a clicking noise on your Toyota Aygo, it is plausible that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the circumstance, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I notice a clicking noise on Toyota Aygo coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Toyota Aygo once you pass a speed bump, it is extremely plausible that your suspension block is the reason of the noise. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To examine if this is the issue that worries you, take a dented road and, at low speed, pay attention to the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them soon as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you are subject to a clicking noise on your Toyota Aygo at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a cause. To examine the shape of the spring, position the automobile on a flat surface and measure that the heights from the ground to the bottom of the body are equivalent on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you discover a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, be sure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should think about changing it or them. If you have the feeling that this noise is more like a squeaking noise on Toyota Aygo than a clicking noise, don’t hesitate to consult this article.
