I discover a clicking noise on Lexus CT on my engine
Check your high engine
If you discover a clicking noise on Lexus CT, and this sound is located at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two elements can be the triggers of these ticking noises on Lexus CT. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally 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 case, remember to change them.
Check your low engine
If you have founded the zone of origin of the Lexus CT 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 repairs are very complex and most mechanics will recommend you to swap the engine of your Lexus CT.
Combustion problem
Finally, if you have the feeling that this clicking noise on Lexus CT is related to the combustion of your engine, there are three possible origins of it. Check the condition 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 components 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 circumstance, do not hesitate to consult this document which deals in detail with the different injection sounds on Lexus CT.
I discover a clicking noise on Lexus CT in my direction
Check the condition of the gimbals
One of the most regular triggers of a clicking noises in the direction of your Lexus CT 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 create a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will harm the cardan shaft very quickly and must be replaced rapidly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Check the rest of your direction
Finally, when you recognise a clicking noise on your Lexus CT, 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.
I discover a clicking noise on Lexus CT coming from my suspensions
Check the suspension
If you encounter a clicking noise on your Lexus CT when you pass a speed bump, it is very conceivable that your suspension block is the reason of the sound. 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 issue that concerns you, take a dented road and, at low speed, listen to the sound originating from your front axle when you pass over holes. If these are the cups, consider changing them as soon as possible as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Lexus CT at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a explanation. To verify the condition of the spring, place the vehicle on a flat surface and measure that the heights from the ground to the bottom of the body are similar on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too significant it denotes that most likely your springs are worn, if you observe a leak go a little further in the article to have the solution 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 swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Lexus CT than a clicking noise, don’t hesitate to consult this article.
