Check your high engine
If you find out a clicking noise on Volvo XC90, and this noise is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two parts can be the causes of these ticking noises on Volvo XC90. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will hear 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 case, remember to change them.
Check your low engine
If you have founded the spot of origin of the Volvo XC90 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 advise you to swap the engine of your Volvo XC90.
Finally, if you have the feeling that this clicking noise on Volvo XC90 is linked to the combustion of your engine, there are three possible causes of it. Check the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable 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 destroyed.

I find out a clicking noise on Volvo XC90 in my direction
Check the state of the gimbals
One of the most common reasons of a clicking noises in the direction of your Volvo XC90 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 make a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be swapped rapidly, 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 know a clicking noise on your Volvo XC90, it is conceivable 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 find out a clicking noise on Volvo XC90 coming from my suspensions
Check the suspension
If you encounter a clicking noise on your Volvo XC90 each time you pass a speed bump, it is really conceivable that your suspension block is the reason of the noise. Indeed, 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 check if this is the trouble that concerns you, take a dented road and, at low speed, focus on the noise coming from your front axle when ever you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Volvo XC90 at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a explanation. To check the state 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 check between the front and rear, if there is a gap too large it means 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, 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. If you have the feeling that this noise is more like a squeaking noise on Volvo XC90 than a clicking noise, don’t hesitate to consult this article.
