Listening noises from your auto frequently is never comforting, so hearing noises on your Land Rover Discovery suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a small trouble as well as a warning of a much larger repair to come. In any case, it is fundamental to check the cause and take the necessary actions to solve the trouble, it is with this aim in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, what can be the cause 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 Land Rover Discovery
Check Land Rover Discovery suspension
If you encounter a suspension noise when you pass a speed bump on your Land Rover Discovery, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To examine if this is the trouble that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing 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 looked for for “Land Rover Discovery 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion. To examine 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 changing it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Land Rover Discovery passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change 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 causes of your noises, to examine it, place it under the car and apply twists on each of its components to examine that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your Land Rover Discovery to your auto mechanic or replace 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 Land Rover Discovery, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Bear in mind to examine by passing under your car the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a evident fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Land Rover Discovery. To swap them go to your mechanic.

If, despite all its assumptions, you still can’t uncover the origin of the noise your Land Rover Discovery makes when you pass a speed bump, we recommend you to refer to this article on a loud noise on Land Rover Discovery or to visit your auto mechanic in order to carry an in-depth check on your Land Rover Discovery and discover this trouble.
