Suspension cracking noise Toyota Avensis
Check Toyota Avensis suspension
If you notice a suspension noise when you pass a speed bump on your Toyota Avensis, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 check 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 changing them quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Toyota Avensis 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their operation is degraded and it is possible to experience a sound when they are in torsion. To check 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 circumstances you should consider replacing it or them.

Check steering hinges/stabilizer bar

The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to check it, position it under the vehicle and apply twists on each of its elements to check that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Keep in mind to take your Toyota Avensis to your technician or swap 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 Toyota Avensis, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Remember to check by passing under your vehicle 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 dried out and create noise, in which case remove them from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a evident fatigue of these will generate 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 Toyota Avensis. To replace them go to your technician.
