Listening noises from your auto often is never comforting, so hearing noises on your volvo xc70 suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is fundamental to check the origin and take the necessary actions to eliminate the problem, it is with this objective in mind that we wanted to write this document to help you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, after that, what can be the cause of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise volvo xc70
Check volvo xc70 suspension
If you experience a suspension noise when you pass a speed bump on your volvo xc70, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To verify if this is the problem that worries you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping them quickly or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “volvo xc70 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 old and the dirt/dust builds up inside them their action is degraded and it is possible to experience a noise when they are in torsion. To verify 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 conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on volvo xc70, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your volvo xc70 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the components that may have been destroyed 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 verify it, put it under the car and apply twists on each of its components to verify that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto technician or swap them if they are involved.
squeaky noise speed bump volvo xc70
Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your volvo xc70, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Please remember to verify by going under your car the condition of the paint on your bar which will tell us if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case remove them from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a noticable weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your volvo xc70. To change them go to your auto technician.
Other speed bump noise volvo xc70
If, even though all its assumptions, you still can’t locate the origin of the noise your volvo xc70 makes when you pass a speed bump, we advise you to consult this article on a loud noise on volvo xc70 or to visit your auto technician in order to carry an in-depth check on your volvo xc70 and identify this problem.
