Listening noises from your auto regularly is never comforting, so hearing noises on your volvo v70 suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the cause and take the necessary actions to resolve the issue, it is with this objective in mind that we wanted to write this content to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, 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 v70
Check volvo v70 suspension
If you experience a suspension noise when you pass a speed bump on your volvo v70, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are old, 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 verify if this is the issue that worries you, take a dented road and listen 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 affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “volvo v70 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on volvo v70, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your volvo v70 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 your situation, the parts that may have been damaged 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, place it under the automobile and apply twists on each of its components to verify that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your mechanic or change them if they are involved.
squeaky noise speed bump volvo v70
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 volvo v70, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Please remember to verify by going under your automobile the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case remove them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your volvo v70. To swap them go to your technician.
