Suspension cracking noise Land Rover Range Rover Sport

Check Land Rover Range Rover Sport suspension

If you experience a suspension noise when you pass a speed bump on your Land Rover Range Rover Sport, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 issue that worries you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them as soon as possible or you may affect other parts and have to make more important fixes.

Check the cardan shaft

If you are here because you have searched for “Land Rover Range Rover Sport 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Land Rover Range Rover Sport, don’t hesitate to read this content.

Check steering hinges/stabilizer bar

Finally, when you detect a suspension noise when your Land Rover Range Rover Sport passes over a speed bumps, it is imaginable 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 the case, the components that may have been damaged 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, position it under the vehicle and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Keep in mind to take your Land Rover Range Rover Sport to your mechanic 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 Land Rover Range Rover Sport, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Keep in mind to verify by passing 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 dry and cause noise, in which case take them off from the cradle and grease them, this should fix the issue.

Check engine silentblocks

Finally, last case that we can verify 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 fatigue of these will make 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 Range Rover Sport. To swap them go to your auto mechanic.
