Being subject to recurring noise on your automobile tends to be disturbing, a automobile is so elaborate that it is generally difficult to determine its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Lexus ES, we will most likely be able to support you. In fact, our editorial staff decided to compose this document in order to review the main causes of a clicking noise on Lexus ES. This is why, firstly, we will see what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the sources of clicking noise on Lexus ES coming from your suspensions.
I perceive a clicking noise on Lexus ES from my engine
Verify your high engine
If you perceive a clicking noise on Lexus ES, and this sound is located at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two elements can be the causes of these ticking noises on Lexus ES. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, generally when cold and disappear 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 founded the region of origin of the Lexus ES clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both cases, the risk in the long term is the breakage of the motor. These two fixes are very difficult and most mechanics will suggest you to change the engine of your Lexus ES.
Combustion problem
Finally, if you have the feeling that this clicking noise on Lexus ES is linked to the combustion of your engine, there are three possible origins of it. Verify the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible 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 cause, 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 ES.
I perceive a clicking noise on Lexus ES in my direction
Verify the condition of the gimbals
One of the most regular causes of a clicking noises in the direction of your Lexus ES 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 generate a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be changed rapidly, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it. If you would like more detailed information about gimbals noises on Lexus ES, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you detect a clicking noise on your Lexus ES, it is plausible 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 perceive a clicking noise on Lexus ES coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Lexus ES each time you pass a speed bump, it is really plausible that your suspension block is the cause of the sound. In fact, it may be the suspension cups, which, when they are dead, 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 check if this is the trouble that worries you, take a dented road and, at low speed, pay attention to the sound coming from your front axle when ever 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 detect a clicking noise on your Lexus ES at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a explanation. To check the state of the spring, position 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 check between the front and rear, if there is a gap too significant it denotes that most likely your springs are worn, if you discover 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 consider swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Lexus ES than a clicking noise, don’t hesitate to consult this article.
