Listening noises from your car often is never reassuring, so hearing noises on your Ram ProMaster suspensions when you pass a speed bump can be stressing. This warning sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to eliminate the trouble, it is with this goal in mind that we wanted to write this content to help 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 Ram ProMaster
Check Ram ProMaster suspension
If you encounter a suspension noise when you pass a speed bump on your Ram ProMaster, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the trouble that worries you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them fairly quickly or you may damage other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Ram ProMaster 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is degraded and it is possible to experience a sound when they are in torsion.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 circumstances you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Ram ProMaster passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify direction. If this is the situation, the components that may have been broken by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins 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 expected to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto mechanic or change them if they are involved.
squeaky noise speed bump Ram ProMaster
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 Ram ProMaster, 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 generate this squeaking noise. Bear in mind to check by passing under your car the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a pronounced 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 Ram ProMaster. To change them go to your mechanic.
Other speed bump noise Ram ProMaster
If, even though all its assumptions, you still can’t uncover the source of the noise your Ram ProMaster makes when you pass a speed bump, we recommend you to refer to this article on a loud noise on Ram ProMaster or to visit your auto mechanic in order to carry an in-depth check on your Ram ProMaster and identify this trouble.
