Hearing noises from your auto regularly is never comforting, so discovering noises on your Ford Expedition suspensions when you go over a speed bump can be worrying. This indicator may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to correct the problem, it is with this intention in mind that we wanted to write this article to support 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 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 Ford Expedition
Check Ford Expedition suspension
If you experience a suspension noise when you pass a speed bump on your Ford Expedition, 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 dead, 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 check if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them as soon as possible or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Ford Expedition 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on Ford Expedition, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Ford Expedition 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 change direction. If this is your situation, the parts 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 check it, put it under the car and apply twists on each of its components to check 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 Ford Expedition to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Ford Expedition
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 Ford Expedition, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Keep in mind to check by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a obvious weakness of these will make 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 Ford Expedition. To swap them go to your technician.
Other speed bump noise Ford Expedition
If, despite all its assumptions, you still can’t find the source of the noise your Ford Expedition makes when you pass a speed bump, we advise you to consult this content on a loud noise on Ford Expedition or to visit your auto mechanic in order to carry an in-depth check on your Ford Expedition and identify this problem.
