      Hi everyone. I'd like to run a scenario by you and get
      your input as to the probable cause. I had a bad
      thrust arm bushing (really loose). I was told by a
      mechanic that I could drive with it until he could fix
      it in a few weeks. Several days later(at very low
      speed) There was a TREMENDOUS front end noise. Upon
      inspecting the car, I noticed that I could SINK the
      drivers side bumper (could actually HEAR the shock
      deflate) while pushing down. I did this 3 times (I
      pulled it back up, pushed back down) and after 3
      tries, I got the feeling of the spring seating itself
      again (I.E it felt normal when pushing on the bumper.
      The mechanic would not tell me what happened. He
      replaced the thrust arm on BOTH sides and put in new
      Bilsteins because (and I quote) "when you remove the
      factory installed struts you have to destroy them to
      get them off". I smell a rat, but I'd like to know
      what your thoughts are. I think that the thrust arm
      snapped and knocked the spring off. I also think it's
      possible to remove factory installed struts without
      destroying them. Your thoughts would be appreciated.
      Thanks. Guy
