I have been hearing a creaking sound from rear suspension. Pulled the wheels off to take a look today.

The driver side rear suspension has the eibach spring cracked in half. No idea why or how that happened.

 

Maybe it is a defect?

 

I'm guessing that you haven't done anything that would put undue stress on the springs? No unintentional offroad excursions or the like? If so then a manufacturing defect is not a bad guess.

 

Yeah just regular street driving. I've had this suspension setup for a few years now though. Maybe I'll contact eibach.

 

I believe eibach has a lifetime warranty, at least.

 

defect. act of god.

 

I bought them second had lightly used so I'd doubt it would cover anyone other than original purchaser but ill contact them anyways as I'm sure it's not normal
It cracked.

 

looks like a defect in the metal and the location is suspect too. Every cracked spring I have seen was due to exposure to the elements and accelerated wear because of it and the break was parallel or diagonal to the spring wire, not on an almost 90 degree like that.

 

Yeah who knows. Called up eibach and ground control about it. Said they never heard it happen like that before.
Anyways just bought another spring from ground control for $70 shipped.

 

Is this what you have?
