Check your high engine
If you listen to a clicking noise on Renualt Express, 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 elements can be the triggers of these ticking noises on Renualt Express. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, often when cold and go away when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this circumstance, remember to change them.
Check your low engine
If you have identified the spot of source of the Renualt Express clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both situations, the risk in the long term is the breakage of the motor. These two maintenance are very complicated and most mechanics will encourage you to change the engine of your Renualt Express.
Combustion problem
Finally, if you have the feeling that this clicking noise on Renualt Express is connected to the combustion of your engine, there are three possible origins of it. Check 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 elements to promote good combustion. And finally, the most classic cause, comes from your injection, which is either blocked or one or more injectors are damaged.

Check the condition of the gimbals
One of the most common triggers of a clicking noises in the direction of your Renualt Express is related to the direction of the automobile. 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 generate 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 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 recognise a clicking noise on your Renualt Express, 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.

Check the suspension
If you experience a clicking noise on your Renualt Express each time you pass a speed bump, it is very conceivable that your suspension block is the reason of the noise. 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 examine if this is the problem that worries you, take a dented road and, at low speed, focus on the noise originating 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 damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Renualt Express at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To examine the shape of the spring, place the vehicle 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 examine between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you find out 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 consider swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Renualt Express than a clicking noise, don’t hesitate to consult this article.
