If you have already experienced a clicking noise on your Renault Laguna 2, we will most likely be able to support you. In fact, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Renault Laguna 2. This is why, firstly, we will check out what are the origins of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the sources of clicking noise on Renault Laguna 2 coming from your suspensions.
I perceive a clicking noise on Renault Laguna 2 from my engine
Verify your high engine
If you perceive a clicking noise on Renault Laguna 2, and this sound is located at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two parts can be the triggers of these ticking noises on Renault Laguna 2. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will perceive these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this situation, remember to change them.
Verify your low engine
If you have determined the zone of source of the Renault Laguna 2 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both cases, the risk in the long term is the breakage of the motor. These two maintenance are very complex and most mechanics will suggest you to change the engine of your Renault Laguna 2.
Combustion problem
Finally, if you have the feeling that this clicking noise on Renault Laguna 2 is connected to the combustion of your engine, there are three possible triggers of it. Verify the condition 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 cause, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to read this document which deals in detail with the different injection sounds on Renault Laguna 2.
I perceive a clicking noise on Renault Laguna 2 in my direction
Verify the condition of the gimbals
One of the most common causes of a clicking noises in the direction of your Renault Laguna 2 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 get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be replaced very quickly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Verify the rest of your direction
Finally, when you find out a clicking noise on your Renault Laguna 2, 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 case, 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 perceive a clicking noise on Renault Laguna 2 coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Renault Laguna 2 when you pass a speed bump, it is very conceivable that your suspension block is the reason of the sound. In fact, it may be the suspension cups, which, when they are dead, 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 trouble that worries you, take a dented road and, at low speed, pay attention to the sound coming from your front axle when ever you pass over holes. If these are the cups, consider changing them as soon as possible as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Renault Laguna 2 at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To examine the condition of the spring, place the automobile 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 large it means that most likely your springs are worn, if you see 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 think about replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Renault Laguna 2 than a clicking noise, don’t hesitate to consult this article.
