Examine your low engine
If you have founded the region of source of the Lexus NX clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers.

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 parts to promote good combustion. And finally, the most classic trigger, comes from your injection, which is either blocked or one or more injectors are injured.

Examine the state of the gimbals
One of the most common causes of a clicking noises in the direction of your Lexus NX is linked 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 get closer to the stop zone of your steering. A bellows with holes will damage 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.

I find out a clicking noise on Lexus NX coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Lexus NX when you pass a speed bump, it is extremely conceivable that your suspension block is the induce of the noise. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function and during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 verify if this is the problem that concerns you, take a dented road and, at low speed, listen to the noise coming from your front axle when you pass over holes. If these are the cups, consider changing them soon as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Lexus NX at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a reason. 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 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 solution 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 think about replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Lexus NX than a clicking noise, don’t hesitate to consult this article.
