Verify your high engine

Two elements can be the triggers of these ticking noises on Volvo S90. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will perceive these clicking noises, often when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this circumstance, remember to change them.

Verify your low engine

If you have distinguished the area of source of the Volvo S90 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 fixes are very complicated and most mechanics will encourage you to swap the engine of your Volvo S90.

Combustion problem

Verify 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 destroyed.

Verify the state of the gimbals

One of the most common triggers of a clicking noises in the direction of your Volvo S90 is associated with 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 approach the stop zone of your steering. A bellows with holes will affect 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.

Verify the suspension

If you encounter a clicking noise on your Volvo S90 when you pass a speed bump, it is really possible that your suspension block is the induce 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To examine if this is the issue that concerns you, take a dented road and, at low speed, listen 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 affect other parts and require more expensive repairs.

Check spring and cylinder

If you hear a clicking noise on your Volvo S90 at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a reason. To examine the state 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 similar on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too large it denotes that most likely your springs are worn, if you find out a leak go a little further in the article to have the answer 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 think about swapping it or them.
