I was under the van this weekend and grabbed hold of the stabilizer links (verticle bars attached to the shock?) and they are definatley making noise. The bushings (further back, to the rear) didn't appear to have any warping, or "air" between them and the metal, and the noise was coming from the verticle sway bar link....
SHould I pay someone to change both these areas.
I have the jacks, and jack stands, but don't want to get over my head if it is too much work.
