Suspension cracking noise Dacia Logan
Check Dacia Logan suspension
If you experience a suspension noise when you pass a speed bump on your Dacia Logan, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and pay attention to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Dacia Logan suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a sound when they are in torsion. To examine this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Dacia Logan, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Dacia Logan passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the components that may have been affected by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to examine it, put it under the automobile and apply twists on each of its elements to examine that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or swap them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Dacia Logan, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Keep in mind to examine by going under your automobile the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case disassemble them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Dacia Logan. To replace them go to your auto mechanic.
