Verify your high engine
If you listen to a clicking noise on Lexus IS, 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 Lexus IS. 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 disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this circumstance, remember to change them.
Verify your low engine
If you have identified the zone of source of the Lexus IS 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 maintenance are very difficult and most mechanics will advise you to replace the engine of your Lexus IS.
Combustion problem
Finally, if you have the feeling that this clicking noise on Lexus IS is in connection with 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 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 reason, comes from your injection, which is either blocked or one or more injectors are injured.

I listen to a clicking noise on Lexus IS in my direction
Verify the state of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Lexus IS is linked to 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 generate a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be swapped rapidly, 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 find out a clicking noise on your Lexus IS, 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 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.

Verify the suspension
If you experience a clicking noise on your Lexus IS when you pass a speed bump, it is very conceivable that your suspension block is the induce of the noise. 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 verify if this is the trouble that concerns you, take a dented road and, at low speed, focus on the noise originating 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 hear a clicking noise on your Lexus IS at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To verify the condition of the spring, position the automobile 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 suggests that that most likely your springs are worn, if you observe 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 think about changing it or them. If you have the feeling that this noise is more like a squeaking noise on Lexus IS than a clicking noise, don’t hesitate to consult this article.
