I installed a set of Eibach 1.5" coils in my '90 SC a few months back, and after a day or two, an annoying "squeak" started. I took the car to my buddy's speed shop, and we narrowed the "squeak" down. Turns out that on the front coils, the upper 4 or 5 winds of the coil are very close together (less than an 1/8"), and when mild to heavy bumps are hit, the winds touch, and when they separate, they SQUEAK! We confirmed this by putting some moly grease on the winds, bounced the car, and the squeak was gone....... until the moly wore off.
I have talked to Eibach about this, and they say the coils are installed wrong. When I tell them that they only go in one way, they tell me that they need to be indexed. They say "Leave a ¼" to ½" space between the end of the coil and the spring seat pocket. This will help prevent spring noise when encountering large bumps." When I tell them again that they only go in one way, they insist that they aren't indexed.
Now, from what I can tell, you can't index them, because if you leave the space, the coils will just seat (like they are now) once the coil is expanded.
So, who runs Eibachs? Any problems? Am I missing something? Should I sell her and go back to my Bronco?
