Hello guys,
First I apologize for making a new thread about this, but I figured it might benefit someone in the future.
As you might know, I only had the front Eibachs' on for a while, and the noise was driving me nuts, some people told me it's the axle..etc. I don't want to bore you with the whole story, but recently I installed the rear Eibachs' as well, and the noise is now gone! So my theory is that the Eibachs' (front) were compressed a lot before, and that's where the noise was coming from. (rears were oem, fronts were Eibach).
Now that I have Eibachs' all around, the noise is gone. It can only be heard on speed bumps, or when the front springs deform (compress).
I saw a couple of posts where people were complaining about the noise being only on one side, it could be the same problem, or possibly a manufacturing error where one spring is stiffer than the other, swapping the front springs might solve the problem.
That's just my theory, I hope it helps others in getting rid of that noise!
