hmm. I am having my Bilsteins (Manny, we talked about this. HDs, no springs - trying to save $) next Friday, and they are going to look at it. Have to say it does remind me of my old 300d, which was MUCH worse, but turned out to be the axles. All the fluid leaked and killed them both. Not sure how they are set up on this car, but sure feels similar. Center support bearing? What does this do?
