Suspension cracking noise Chevrolet Volt

Check Chevrolet Volt suspension

If you notice a suspension noise when you pass a speed bump on your Chevrolet Volt, 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 function during small bumps that compress the suspensions. To examine if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them as soon as possible or you may affect other parts and have to make more important repairs.

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.

Check the stabilizer bar

If, however, you have a noise that is more like a squeak when you pass a speed bump with your Chevrolet Volt, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Please remember to examine by going under your automobile the condition of the paint on your bar which will show if there is friction.

Check engine silentblocks
