E36 Bilstein Failure

About 18 months ago I had my suspension overhauled on my E36, new struts and shocks (Bilsteins), control arms, bushings, rtb's, etc. Over the past six months, however, I began to feel some play in the
front end, as well as some squeaking and creaking. When I did my own inspection, I found that my lower control arm bushings were hamburger (something that I thought was replaced, but was not). I had those replaced by a different shop.
The squeaking and creaking never went away and has gotten worse. When I push down over the struct mounts, I can hear the squeaking. As such, I brought it to another shop and was told that my front Bilsteins were shot. Curiously, however, I only have 30K on my new struts. Is is possible that my Bilsteins, of presumably such good quality, are shot? I had thought that it might be the upper strut mount bushings, as those were never repleaced and are still the originals (car has 130K).
Naturally, I have an issue with the shop that overhauled my suspension. As this is not the first component that I have suspected that I might have been screwed on. I can confirm that other parts that I had replaced, were not, namely- lower control arm bushings and radiator (nonetheless radiator was replaced by shop when I came back for third time). Needless to say, I do not trust that shop and am in the process of building a case against the same. Which I will undoubtedly prevail.
Despite the foregoing, any thoughts on the Bilsteins? Do they fail so prematurely? My car is a daily driver and I do not abuse it by way of handling.
Any thoughts appreciated.

Could be a bushing issue. Could also just be the rubber pads that go between the springs and the body. Squirt a little light oil on the top and bottom of the spring... of the noise goes away, it's the pads. It won't hurt anything to leave them alone, it's just noisy and annoying.
When you did the shocks you should have replaced the pads, but if you had a shop do it for you, you never really know what they did. It is usually a good idea just to replace all rubber parts in the vicinity when you have anything apart.

I have repeatedly had to replace Bilsteins around the 160,000 mile mark, although the most recent has lasted around 240,000. I think you're somewhat below that. --scott
