Suspension cracking noise Mercedes Benz E Class
Check Mercedes Benz E Class suspension
If you notice a suspension noise when you pass a speed bump on your Mercedes Benz E Class, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 examine if this is the issue that concerns you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them quickly or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Mercedes Benz E Class 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 old and the dirt/dust amasses inside them their action 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 situations you should consider changing it or them.

Check the stabilizer bar

Second possible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case remove them from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last case 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 car, a obvious weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Mercedes Benz E Class.
