Listening noises from your car often is never reassuring, so listening noises on your Land Rover Defender suspensions when you pass a speed bump can be worrying. This sign may be a sign of a small issue as well as a warning of a much larger repair to come. In any case, it is important to check the source and take the necessary actions to correct the issue, it is with this objective in mind that we wanted to write this article to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, 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 Defender
Check Land Rover Defender suspension
If you experience a suspension noise when you pass a speed bump on your Land Rover Defender, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing 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 researched for “Land Rover Defender 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 amasses inside them their functions is deteriorated 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 make a turn at low speed. If it cracks in these two cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Land Rover Defender, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Land Rover Defender 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 adjust direction. If this is your situation, the components that may have been destroyed 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 examine it, position it under the vehicle and apply twists on each of its elements to examine that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto technician or replace them if they are involved.
squeaky noise speed bump Land Rover Defender
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Land Rover Defender, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Please remember to examine by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case remove them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will create 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 Land Rover Defender. To replace them go to your technician.
Other speed bump noise Land Rover Defender
If, even though all its assumptions, you still can’t uncover the source of the noise your Land Rover Defender makes when you pass a speed bump, we recommend you to read this content on a loud noise on Land Rover Defender or to visit your auto technician in order to carry an in-depth check on your Land Rover Defender and find this issue.
