I notice a clicking noise on Toyota Avalon on my engine

Check your high engine

If you notice a clicking noise on Toyota Avalon, and this noise is located at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two parts can be the triggers of these ticking noises on Toyota Avalon. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, generally when cold and go away when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this situation, remember to change them.

Check your low engine

If you have distinguished the region of source of the Toyota Avalon 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 maintenance are very difficult and most mechanics will suggest you to change the engine of your Toyota Avalon.

Combustion problem

Finally, if you have the feeling that this clicking noise on Toyota Avalon is in connection with the combustion of your engine, there are three possible origins of it. Check the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is possible 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 trigger, comes from your injection, which is either blocked or one or more injectors are damaged. In this case, do not hesitate to read this document which deals in detail with the different injection sounds on Toyota Avalon.

I notice a clicking noise on Toyota Avalon in my direction

Check the state of the gimbals

One of the most regular triggers of a clicking noises in the direction of your Toyota Avalon is related to the direction of the car. 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 affect the cardan shaft very quickly and must be swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Check the rest of your direction

Finally, when you recognise a clicking noise on your Toyota Avalon, it is possible 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 notice a clicking noise on Toyota Avalon coming from my suspensions

Check the suspension

If you experience a clicking noise on your Toyota Avalon each time you pass a speed bump, it is highly possible that your suspension block is the induce of the noise. 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 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 soon as this may affect other parts and require more expensive repairs.

Check spring and cylinder

If you hear a clicking noise on your Toyota Avalon at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a cause. To verify the shape 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 suggests that that most likely your springs are worn, if you discover 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 think about changing it or them. If you have the feeling that this noise is more like a squeaking noise on Toyota Avalon than a clicking noise, don’t hesitate to consult this article.
