Examine your high engine
If you notice a clicking noise on Lexus GS, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two parts can be the causes of these ticking noises on Lexus GS.

Examine your low engine
If you have distinguished the zone of origin of the Lexus GS clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes.

Examine 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 parts 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.

Examine the state of the gimbals
One of the most common triggers of a clicking noises in the direction of your Lexus GS is related to the direction of the vehicle. 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 damage the cardan shaft very quickly and must be changed in a short time, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it.

Examine the suspension
If you encounter a clicking noise on your Lexus GS 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function and during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, focus on the noise coming 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 notice a clicking noise on your Lexus GS at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a reason. To verify the condition of the spring, place the car 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 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 consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on Lexus GS than a clicking noise, don’t hesitate to consult this article.
