Being subject to regular noise on your vehicle tends to be annoying, a vehicle is so sophisticated that it is constantly difficult to situate its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your smart fortwo, we will almost certainly be able to support you. Indeed, our editorial staff decided to compose this content page in order to review the main causes of a clicking noise on smart fortwo. This is why, firstly, we will see what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the origins of clicking noise on smart fortwo coming from your suspensions.
I perceive a clicking noise on smart fortwo on my engine
Examine your high engine
If you perceive a clicking noise on smart fortwo, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two elements can be the causes of these ticking noises on smart fortwo. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally 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 case, remember to change them.
Examine your low engine
If you have identified the area of origin of the smart fortwo clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very complicated and most mechanics will recommend you to replace the engine of your smart fortwo.
Combustion problem
Finally, if you have the feeling that this clicking noise on smart fortwo is in connection with the combustion of your engine, there are three possible triggers of it. Examine the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable 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 trigger, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to check this content page which deals in detail with the different injection sounds on smart fortwo.
I perceive a clicking noise on smart fortwo in my direction
Examine the state of the gimbals
One of the most regular triggers of a clicking noises in the direction of your smart fortwo is related to 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 make a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be swapped rapidly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it. If you would like more detailed information about gimbals noises on smart fortwo, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you experience a clicking noise on your smart fortwo, it is conceivable 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 case, 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 perceive a clicking noise on smart fortwo coming from my suspensions
Examine the suspension
If you experience a clicking noise on your smart fortwo when you pass a speed bump, it is really conceivable that your suspension block is the cause of the noise. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To verify if this is the trouble that concerns you, take a dented road and, at low speed, focus on the noise coming from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your smart fortwo at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To verify the condition of the spring, place the car on a flat surface and measure that the heights from the ground to the bottom of the body are identical on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you observe a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, make 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 swapping it or them. If you have the feeling that this noise is more like a squeaking noise on smart fortwo than a clicking noise, don’t hesitate to consult this article.
