Check Toyota Land Cruiser Serie 120 suspension
If you encounter a suspension noise when you pass a speed bump on your Toyota Land Cruiser Serie 120, 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 dead, 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 trouble 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 changing them fairly quickly or you may affect other parts and have to make more important fixes.
