Has anyone ever figured out what the yellow/green film is on these bushings? The upper control arms rod used similar,yet smaller, bushings.I have NOS of both and the upper's have a green'ish film like the lower in the 1st ebay link you show does. Often thought it was a dry film lubricant?? any ideas...
