I hear a clicking noise on Infiniti QX70 from my engine

Verify your high engine

If you hear a clicking noise on Infiniti QX70, and this noise is located 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 Infiniti QX70. 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 go away 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 founded the zone of source of the Infiniti QX70 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 repairs are very difficult and most mechanics will advise you to swap the engine of your Infiniti QX70.

Combustion problem

Finally, if you have the feeling that this clicking noise on Infiniti QX70 is linked to the combustion of your engine, there are three possible reasons 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 parts to promote good combustion. And finally, the most classic cause, comes from your injection, which is either blocked or one or more injectors are destroyed. In this circumstance, do not hesitate to consult this article which deals in detail with the different injection sounds on Infiniti QX70.

I hear a clicking noise on Infiniti QX70 in my direction

Verify the state of the gimbals

One of the most common causes of a clicking noises in the direction of your Infiniti QX70 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 in a short time, 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 Infiniti QX70, do not hesitate to read this complete guide.

Verify the rest of your direction

Finally, when you experience a clicking noise on your Infiniti QX70, 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 hear a clicking noise on Infiniti QX70 coming from my suspensions

Verify the suspension

If you encounter a clicking noise on your Infiniti QX70 when 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 verify if this is the issue that concerns you, take a dented road and, at low speed, focus on the noise coming 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 detect a clicking noise on your Infiniti QX70 at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a reason. To verify the shape of the spring, position 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 find out 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 consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on Infiniti QX70 than a clicking noise, don’t hesitate to consult this article.
