Strange noise from front suspension


Recommended Posts

I have Bilstein PSS9 installed in my 996TT.

Now i have a strange sound in the front when i'm driving slow ( for example in parking places) and turning my steering. Like a crackle sound or bang.

I have changed the bearings on the top of the suspension and also the ball joints on the trangles under the suspension but that did't help.

The boing sound is from the springs moving in their socket. This can be eliminated by installing the stock thrust bearing and rubber washer. The installation instructions from Bilstein are not that great.

Thanks for the answer.

Stock thrust bearing? Do you mean the bearing on the top of the springs facing the chassis? If so these are completely new. They were changed by Porsche and are stock.

So it can not be this. But i have to say that this sound wasn't there before they changed this bearings ( they changed the bearings because they were worn out). I beleive that something has gone wrong when they put / installed the complete sping/damper back on.

Rubber washer ? Is this something which is between the springs and the grey cup which the spring is resting against on top? I can only see that the spring is resting directly on this grey cup. And of couse this cup is moved as i turn the steering. I don't know if the spring i following this or if it's somethimes stucked?

But i'm also pretty sure that this section in making the sound.

What do you mean?

PSS9 noise

Thanks for very useful info.

They checked this at Porsche today. They found out that the right strut not installed properly. When front wheels was in the air they turned the wheel left / right. On the right side the spring was not follow the support on top. That why it it makes noise.

Left side seems OK.

They have to remount this!
