Discovering noises from your auto frequently is never reassuring, so listening noises on your Mercury Mariner suspensions when you pass a speed bump can be worrying. This warning sign may be a sign of a minor problem as well as a warning of a much larger repair to come. In any case, it is fundamental to check the cause and take the necessary actions to eliminate the problem, it is with this goal in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, 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 Mercury Mariner
Check Mercury Mariner suspension
If you experience a suspension noise when you pass a speed bump on your Mercury Mariner, 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 examine if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them as soon as possible or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Mercury Mariner 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is degraded and it is possible to experience a sound when they are in torsion. To examine 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 circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Mercury Mariner, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Mercury Mariner passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is your situation, the parts that may have been broken by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, place it under the automobile and apply twists on each of its components to examine that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your Mercury Mariner to your auto mechanic or swap them if they are involved.
squeaky noise speed bump Mercury Mariner
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Mercury Mariner, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Please remember to examine by passing under your automobile the condition of the paint on your bar which will tell us if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case remove them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks act 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 happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Mercury Mariner. To replace them go to your mechanic.
Other speed bump noise Mercury Mariner
If, despite all its assumptions, you still can’t uncover the source of the noise your Mercury Mariner makes when you pass a speed bump, we suggest you to read this content on a loud noise on Mercury Mariner or to visit your auto mechanic in order to carry an in-depth check on your Mercury Mariner and determine this problem.
