Being subject to constant noise on your car tends to be disturbing, a car is so sophisticated that it is usually difficult to determine its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Opel Astra, we will most likely be able to help you. In fact, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Opel Astra. 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 Opel Astra coming from your suspensions.
I listen to a clicking noise on Opel Astra on my engine
Check your high engine
If you listen to a clicking noise on Opel Astra, and this sound 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 Opel Astra. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this situation, remember to change them.
Check your low engine
If you have identified the spot of origin of the Opel Astra clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both cases, the risk in the long term is the breakage of the motor. These two fixes are very complex and most mechanics will recommend you to change the engine of your Opel Astra.
Combustion problem
Finally, if you have the feeling that this clicking noise on Opel Astra is in connection with the combustion of your engine, there are three possible reasons of it. Check 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 components 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 case, do not hesitate to read this content page which deals in detail with the different injection sounds on Opel Astra.
I listen to a clicking noise on Opel Astra in my direction
Check the state of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Opel Astra is connected to the direction of the car. 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 approach the stop zone of your steering. A bellows with holes will harm the cardan shaft very quickly and must be replaced rapidly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it. If you would like more detailed information about gimbals noises on Opel Astra, do not hesitate to consult this complete guide.
Check the rest of your direction
Finally, when you find out a clicking noise on your Opel Astra, 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 listen to a clicking noise on Opel Astra coming from my suspensions
Check the suspension
If you experience a clicking noise on your Opel Astra each time you pass a speed bump, it is highly conceivable that your suspension block is the reason of the sound. In fact, 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 function and during small jolts that compress the suspensions. To check if this is the trouble that concerns you, take a dented road and, at low speed, listen to the sound originating from your front axle when you pass over holes. If these are the cups, consider changing them as soon as possible as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Opel Astra at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To check the state of the spring, place the vehicle 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 check between the front and rear, if there is a gap too large it denotes that most likely your springs are worn, if you see a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, ensure 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 consider replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Opel Astra than a clicking noise, don’t hesitate to consult this article.
