I think that you are after the "grommet" type bushing that goes into the lower suspension arm. The stud portion of the link goes thru it with a nut on the bottom. I got mine from the Ford dealer. They were about $5 each. Not too bad to install. These are hard to find in stock at parts houses. Dealers usually have them. They are rubber, and take a beating, and will eventually wear out.
