: Some helpful info for Eibach spring owners.....got squeaking noises?

Up until last week, my Eibach springs have been noise free. I've now got some front-end noises every time I go to slow down (loads up front end). Accelerating doesn't produce any noises but I hear it on some big bumps sometimes. I called Eibach today and we discussed the issue and possible solutions. The progressive spring may be rubbing to the point of causing noise and they provided me a part number (UB0205-5) for a spring isolator. It basically is a thin hardened rubber sleeve with internal adhesive to keep the springs separated. I'll let you know how it works out. I know D3 has nylon sleeving to perform this basic function as well with their units. Just giving you guys a heads up.

While you're at it, might want to ask Eibach how they're dealing with re-homing the MRC sensors. The rears are adjustable to some degree, but the fronts are not.

Here is what I got mailed to me from Eibach. They said I would only need one per side in the front as there is only one "progressive" coil that may touch another. I asked for extras. They have a split so you do not have to remove the coils for installation. There is also a line of sticky glue inside that prevents sliding or shifting:

are these basically the same sleeves D3 uses?

I ordered mine too and will receive them next week. Thanks for finding this for everyone.
The sleeves D3 uses is a nylon sleeve. functionally it is ok, but the issue is that it can bunch up, etc.

Also........you do not have to remove the springs to install, just jack up the car to unload the spring. These are designed exactly for isolating coils.

Wow, that IS a clever design for sure.

Installed one coil isolator on each side and 98.2% of the noise is now gone. I could see where the top coils have been rubbing against each other (paint scratched/marred) and most likely caused the noise. I tried to recreate all the conditions that caused all the noise before and it is completely silent. I remember somewhere in this forum where someone talked about the hard rubber sleeve around the shock hitting against the top of the strut. I'll investigate further to see if it needs to be trimmed a little because I heard something barely perceptible that may be attributed to that sleeve material. For now, I'm relieved the noise is gone.

Thank you VERY much for the info; I am going to order Monday. My eibachs, under load from braking/persons in the car/bumps, make all sorts of odd squeaks and such.

Very glad I dont have to remove the springs to install these either!

I need to verify that the little noise I hear every once in a while is that rubber shield/boot thing needing trimmed. I think it is.

Yep, that is DEFINITELY better than sliding 1/2" heater hose over the ends.........

I pulled my d3 spring in the front. I noticed that the top rubber spring perch has an orientation. With the upper suspension mount bolted in place and the top shock nut off, I rotated the rubber perch and spring until there was a uniform gap between it and the upper suspension mount. I also greased the area were this perch comes in contact with the spring. So far absolutely no noise. I will report back after a week.
