Finding out noises from your car often is never reassuring, so discovering noises on your Lincoln Navigator suspensions when you pass a speed bump can be stressful. This sign may be a sign of a small trouble as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin and take the necessary actions to correct the trouble, it is with this objective in mind that we wanted to write this content 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 reason 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 Navigator
Check Lincoln Navigator suspension
If you experience a suspension noise when you pass a speed bump on your Lincoln Navigator, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. Indeed, 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 function during small bumps that compress the suspensions. To verify if this is the trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them as soon as possible or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Lincoln Navigator suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get old and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a sound 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 Lincoln Navigator, don’t hesitate to check out this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Lincoln Navigator passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is your situation, the components that may have been destroyed by normal 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, position it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or swap them if they are involved.
squeaky noise speed bump Lincoln Navigator
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Lincoln Navigator, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Keep in mind to verify by passing under your car the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them out from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Lincoln Navigator. To change them go to your auto technician.
Other speed bump noise Lincoln Navigator
If, despite all its assumptions, you still can’t find the source of the noise your Lincoln Navigator makes when you pass a speed bump, we encourage you to consult this article on a loud noise on Lincoln Navigator or to visit your auto technician in order to carry an in-depth check on your Lincoln Navigator and determine this trouble.
