Examine your low engine
If you have identified the zone of source of the Acura RDX clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers.

Examine the condition of the gimbals
One of the most regular triggers of a clicking noises in the direction of your Acura RDX is connected 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 replaced in a short time, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Examine the suspension
If you encounter a clicking noise on your Acura RDX when you pass a speed bump, it is extremely possible that your suspension block is the reason of the sound. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function and during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 examine 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 you pass over holes. If these are the cups, consider changing them as soon as possible as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Acura RDX at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a cause. To examine 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 equivalent on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too significant it suggests that that most likely your springs are worn, if you see 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 swapping it or them.
