Verify your low engine
If you have founded the zone of source of the Toyota Highlander clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes.

And finally, the most classic cause, comes from your injection, which is either blocked or one or more injectors are injured.

Verify the condition of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Toyota Highlander is linked 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 harm 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 suspension
If you encounter a clicking noise on your Toyota Highlander once you pass a speed bump, it is very possible that your suspension block is the cause 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function and during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, pay attention to the sound originating 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 hear a clicking noise on your Toyota Highlander at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a cause. To verify the shape of the spring, position the car 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 suggests that 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, 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 changing it or them.
