Finding out noises from your auto frequently is never reassuring, so hearing noises on your GMC Yukon suspensions when you go over a speed bump can be disturbing. This warning sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is fundamental to check the source and take the necessary actions to correct the problem, it is with this goal in mind that we wanted to write this article to help 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 GMC Yukon
Check GMC Yukon suspension
If you encounter a suspension noise when you pass a speed bump on your GMC Yukon, and it is characterized by a “clack” or cracking, it is highly plausible 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 role during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them as soon as possible 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 “GMC Yukon 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on GMC Yukon, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your GMC Yukon 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 vary direction. If this is the situation, the parts that may have been destroyed 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, put it under the automobile and apply twists on each of its elements to examine that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Please remember to take your GMC Yukon to your auto mechanic or replace them if they are involved.
squeaky noise speed bump GMC Yukon
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 GMC Yukon, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Remember to examine by going under your automobile the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them out from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a noticable weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your GMC Yukon. To replace them go to your technician.
Other speed bump noise GMC Yukon
If, even though all its assumptions, you still can’t find the source of the noise your GMC Yukon makes when you pass a speed bump, we suggest you to consult this content on a loud noise on GMC Yukon or to visit your auto mechanic in order to carry an in-depth check on your GMC Yukon and find this problem.
