Being subject to frequent noise on your automobile tends to be frustrating, a automobile is so elaborate that it is usually difficult to situate its origin and even more so to find the part that causes it. If you have already experienced a clicking noise on your GMC Savana, we will probably be able to support you. Indeed, our editorial staff decided to create this document in order to review the main causes of a clicking noise on GMC Savana. This is why, firstly, we will look at 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 origins of clicking noise on GMC Savana coming from your suspensions.
I hear a clicking noise on GMC Savana from my engine
Examine your high engine
If you hear a clicking noise on GMC Savana, and this noise is located at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two elements can be the triggers of these ticking noises on GMC Savana. Either the hydraulic pushers , in general 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 circumstance, remember to change them.
Examine your low engine
If you have distinguished the region of origin of the GMC Savana 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 complicated and most mechanics will suggest you to change the engine of your GMC Savana.
Combustion problem
Finally, if you have the feeling that this clicking noise on GMC Savana is linked to the combustion of your engine, there are three possible triggers of it. Examine 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 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 GMC Savana.
I hear a clicking noise on GMC Savana in my direction
Examine the state of the gimbals
One of the most regular triggers of a clicking noises in the direction of your GMC Savana is linked with 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 create 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 in a short time, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Examine the rest of your direction
Finally, when you detect a clicking noise on your GMC Savana, it is possible 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 hear a clicking noise on GMC Savana coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your GMC Savana each time you pass a speed bump, it is really possible that your suspension block is the cause 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 role and during small jolts that compress the suspensions. To examine if this is the problem that concerns you, take a dented road and, at low speed, pay attention to the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them quickly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your GMC Savana 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 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, be 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 consider swapping it or them. If you have the feeling that this noise is more like a squeaking noise on GMC Savana than a clicking noise, don’t hesitate to consult this article.
