Suspension cracking noise Nissan Altima
Check Nissan Altima suspension
If you experience a suspension noise when you pass a speed bump on your Nissan Altima, 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 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 go 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 vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Nissan Altima 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is degraded and it is possible to experience a sound when they are in torsion.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 conditions you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Nissan Altima passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, 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 causes of your noises, to check it, position it under the vehicle and apply twists on each of its elements to check that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your Nissan Altima to your auto mechanic 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 go over a speed bump with your Nissan Altima, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Keep in mind to check by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a noticable weakness of these will generate 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 Nissan Altima. To replace them go to your auto technician.
