The club competed in the MLS's Western Conference, where they finished in sixth place, or last place, in the Conference.

Thomas Rongen was appointed as Chivas USA's head coach in September 2004, and coached the team until May 2005, when he was replaced with Javier Ledesma on an interim basis.

At the end of June, Hans Westerhof was appointed as the permanent manager until the end of the season.
