Suspension cracking noise Vauxkhall Moka

Check Vauxkhall Moka suspension

If you experience a suspension noise when you pass a speed bump on your Vauxkhall Moka, 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 issue that worries you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping them fairly quickly or you may ruin other parts and have to make more important auto repairs.

Check the cardan shaft

If you are here because you have searched for “Vauxkhall Moka 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed.

Finally, when you find out a suspension noise when your Vauxkhall Moka passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible.

The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to examine it, place it under the vehicle and apply twists on each of its elements to examine that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel.

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 Vauxkhall Moka, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Please remember to examine by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case disassemble them from the cradle and grease them, this should fix the issue.

Check engine silentblocks

Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a obvious fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Vauxkhall Moka. To change them go to your auto technician.
