Your idler arm connects to the center link on the passenger side of your steering linkage. Typically it supports the right hand side of your steering linkage by bolting to the frame and pivoting the same as the pitman arm. Over time the greasable ends and even the holes in the arm can wear causing loose connections and a sloppy steering feel.
