Suspension cracking noise Land Rover Discovery Sport
Check Land Rover Discovery Sport suspension
If you experience a suspension noise when you pass a speed bump on your Land Rover Discovery Sport, and it is categorized 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and focus on 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 vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Land Rover Discovery Sport 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 conditions you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Land Rover Discovery Sport 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 modify direction. If this is your 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 examine it, put it under the car and apply twists on each of its components to examine that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your Land Rover Discovery Sport to your auto technician 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 go over a speed bump with your Land Rover Discovery Sport, 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 cause this squeaking noise. Keep in mind to examine by passing under your car the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case remove them from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point 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 obvious weakness 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 Land Rover Discovery Sport. To swap them go to your auto mechanic.
