Suspension cracking noise Volkswagen Transporter 5
Check Volkswagen Transporter 5 suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Transporter 5, and it is categorized 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 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 verify if this is the issue that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them quickly or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Volkswagen Transporter 5 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Volkswagen Transporter 5 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 your situation, the components that may have been affected by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes 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 special play on one of them, they are meant to resist you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Volkswagen Transporter 5, 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 generate this squeaking noise. Bear in mind to verify by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them off from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last possibility 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 auto, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Volkswagen Transporter 5. To swap them go to your technician.
