Suspension cracking noise Ford F 450

Check Ford F 450 suspension

If you notice a suspension noise when you pass a speed bump on your Ford F 450, 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 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 function during small bumps that compress the suspensions. To verify if this is the issue that concerns you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them fairly quickly or you may ruin other parts and have to make more important vehicle repairs.

Check the cardan shaft

If you are here because you have researched for “Ford F 450 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 old and the dirt/dust builds up inside them their functions 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 make a turn at low speed. If it cracks in these two situations you should consider changing it or them.

Check steering hinges/stabilizer bar

Finally, when you experience a suspension noise when your Ford F 450 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the components that may have been affected by usual 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, place it under the car and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto technician or swap 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 pass a speed bump with your Ford F 450, 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 create this squeaking noise. Keep in mind to verify by going under your car the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should resolve the issue.

Check engine silentblocks

Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced fatigue of these will make 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 Ford F 450. To swap them go to your auto technician.
