In fact, our editorial staff decided to write this article in order to review the main causes of a clicking noise on Mazda CX 7. This is why, firstly, we will see 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 origins of clicking noise on Mazda CX 7 coming from your suspensions.
I notice a clicking noise on Mazda CX 7 located on my engine
Examine your high engine
If you notice a clicking noise on Mazda CX 7, and this sound 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 causes of these ticking noises on Mazda CX 7. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, generally when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this case, remember to change them.
Examine your low engine
If you have identified the spot of source of the Mazda CX 7 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both circumstances, the risk in the long term is the breakage of the motor. These two fixes are very complex and most mechanics will advise you to swap the engine of your Mazda CX 7.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mazda CX 7 is related to the combustion of your engine, there are three possible origins of it. Examine the condition 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 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 article which deals in detail with the different injection sounds on Mazda CX 7.
I notice a clicking noise on Mazda CX 7 in my direction
Examine the condition of the gimbals
One of the most common triggers of a clicking noises in the direction of your Mazda CX 7 is associated with the direction of the automobile. 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 affect the cardan shaft very quickly and must be replaced very quickly, 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 Mazda CX 7, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you know a clicking noise on your Mazda CX 7, 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 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 notice a clicking noise on Mazda CX 7 coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Mazda CX 7 once you pass a speed bump, it is highly plausible that your suspension block is the induce of the sound. In fact, it may be the suspension cups, which, when they are out of date, 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 ever you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Mazda CX 7 at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a cause. To check the condition 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 similar on each side (empty car for measurement). You can also check between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you see a leak go a little further in the article to have the answer 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 Mazda CX 7 than a clicking noise, don’t hesitate to consult this article.
