I discover a clicking noise on Lexus RX on my engine
Verify your high engine
If you discover a clicking noise on Lexus RX, and this noise is located 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 Lexus RX. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will hear 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 distinguished the region of origin of the Lexus RX clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, 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 change the engine of your Lexus RX.
Combustion problem
Finally, if you have the feeling that this clicking noise on Lexus RX is linked to the combustion of your engine, there are three possible origins 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 damaged. In this case, do not hesitate to read this article which deals in detail with the different injection sounds on Lexus RX.
I discover a clicking noise on Lexus RX in my direction
Verify the state of the gimbals
One of the most basic causes of a clicking noises in the direction of your Lexus RX is related 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 create 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 know a clicking noise on your Lexus RX, 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 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 discover a clicking noise on Lexus RX coming from my suspensions
Verify the suspension
If you encounter a clicking noise on your Lexus RX each time you pass a speed bump, it is highly 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 task and during small jolts that compress the suspensions. To verify if this is the problem that worries you, take a dented road and, at low speed, listen to the noise originating from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Lexus RX at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a cause. To verify the state 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 identical 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 observe 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 replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Lexus RX than a clicking noise, don’t hesitate to consult this article.
