Verify your high engine
If you perceive a clicking noise on Infiniti QX80, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two parts can be the triggers of these ticking noises on Infiniti QX80. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, often when cold and go away 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.
Verify your low engine
If you have determined the area of origin of the Infiniti QX80 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both cases, the risk in the long term is the breakage of the motor. These two fixes are very complicated and most mechanics will advise you to change the engine of your Infiniti QX80.
Combustion problem

Verify 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 cause, comes from your injection, which is either blocked or one or more injectors are damaged.

Verify the state of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Infiniti QX80 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 generate 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 in a short time, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Verify the rest of your direction
Finally, when you experience a clicking noise on your Infiniti QX80, it is conceivable that it is the direction that is involved.

Verify the suspension
If you encounter a clicking noise on your Infiniti QX80 each time you pass a speed bump, it is really conceivable that your suspension block is the induce of the noise. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To verify if this is the trouble that worries 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 soon as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Infiniti QX80 at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a cause. To verify the shape 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 equivalent on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too significant 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, 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 consider changing it or them.
