So driving to work this morning with the window down I could here a terrible squeaking type noise on the range. I have narrowed it down to the o/s/r air spring, it only does it at normal ride height not when low or off road heights. I jacked the car up and sprayed the bag with penertrating fluid and it has improved it but not cured it. Any ideas on this? It kinda sounds like its coming from inside the bag. It dosent appear to be loose or anything.
