Finding out noises from your automobile often is never comforting, so discovering noises on your Lincoln MKZ suspensions when you go over a speed bump can be stressing. This indicator may be a sign of a minor trouble 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 resolve the trouble, it is with this intention in mind that we wanted to write this article to help you see more clearly. We will first see the possible reasons 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 Lincoln MKZ
Check Lincoln MKZ suspension
If you experience a suspension noise when you pass a speed bump on your Lincoln MKZ, and it is characterized by a “clack” or cracking, it is highly possible 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the trouble that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them quickly or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Lincoln MKZ 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion. To check 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 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 Lincoln MKZ, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Lincoln MKZ 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 situation, the components that may have been broken by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, place it under the vehicle and apply twists on each of its elements to check that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Lincoln MKZ to your mechanic or replace them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Lincoln MKZ, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Remember to check by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a noticable weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Lincoln MKZ. To replace them go to your auto technician.
Other speed bump noise Lincoln MKZ
If, despite all its assumptions, you still can’t locate the source of the noise your Lincoln MKZ makes when you pass a speed bump, we advise you to read this article on a loud noise on Lincoln MKZ or to visit your mechanic in order to carry an in-depth check on your Lincoln MKZ and identify this trouble.
