Suspension cracking noise Toyota Land Cruiser Serie 90
Check Toyota Land Cruiser Serie 90 suspension
If you experience a suspension noise when you pass a speed bump on your Toyota Land Cruiser Serie 90, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, 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 function during small bumps that compress the suspensions. To examine if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them as soon as possible or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Toyota Land Cruiser Serie 90 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Toyota Land Cruiser Serie 90 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 vary direction. If this is the 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, place 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 endure you quite strongly over their entire travel. Please remember to take your vehicle to your 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 Toyota Land Cruiser Serie 90, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Please remember to examine by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case remove them from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the vehicle, a pronounced fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Toyota Land Cruiser Serie 90. To change them go to your auto technician.
