Suspension cracking noise Mercedes Benz GL Class

Check Mercedes Benz GL Class suspension

If you encounter a suspension noise when you pass a speed bump on your Mercedes Benz GL Class, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 job during small bumps that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of changing them fairly quickly or you may affect other parts and have to make more important auto repairs.

Check the cardan shaft

If you are here because you have looked for for “Mercedes Benz GL Class 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two situations you should consider swapping it or them.

Check steering hinges/stabilizer bar

Finally, when you know a suspension noise when your Mercedes Benz GL Class passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you vary direction. If this is your situation, the components that may have been damaged 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 verify it, position it under the automobile 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.

Check the stabilizer bar

If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Mercedes Benz GL Class, 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 automobile the condition of the paint on your bar which will show if there is friction. Second possible explanation, 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 resolve the problem.

Check engine silentblocks

Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Mercedes Benz GL Class. To replace them go to your mechanic.
