Suspension cracking noise Ram ProMaster City

Check Ram ProMaster City suspension

If you experience a suspension noise when you pass a speed bump on your Ram ProMaster City, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, 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 job during small bumps that compress the suspensions. To verify if this is the trouble that worries you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of changing 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 researched for “Ram ProMaster City 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 circumstances you should consider swapping it or them.

Check steering hinges/stabilizer bar

Finally, when you find out a suspension noise when your Ram ProMaster City 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 modify direction. If this is the situation, the parts that may have been affected 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 verify it, put it under the vehicle and apply twists on each of its components to verify that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician or change them if they are involved.

Check the stabilizer bar

If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Ram ProMaster City, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Remember to verify by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, 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 resolve the trouble.

Check engine silentblocks

Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a evident fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Ram ProMaster City. To swap them go to your auto mechanic.
