Suspension cracking noise Jeep Wrangler
Check Jeep Wrangler suspension
If you experience a suspension noise when you pass a speed bump on your Jeep Wrangler, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are old, 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 verify if this is the problem that concerns you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping them quickly or you may ruin other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Jeep Wrangler 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is degraded and it is possible to experience a sound when they are in torsion.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 replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Jeep Wrangler passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is your situation, the parts that may have been broken by usual 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, place it under the automobile and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your Jeep Wrangler to your auto technician or replace them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Jeep Wrangler, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Remember to verify by passing under your automobile the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case disassemble them from the cradle and grease them, this should eliminate the problem.
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 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 appears when you pass a speed bumps or any holes with your Jeep Wrangler. To change them go to your auto technician.
