Keep the rear axle centered and steady over bumps and crosswinds with the Mevotech Supreme Suspension Track Bar CMS40109. This rear track bar (also called a suspension track bar) locates the rear axle laterally, tying it to the frame so the axle stays positioned side-to-side under load and while cornering. It drops in as a direct-fit replacement for the 2003-2011 Ford Crown Victoria, 2003-2009 Lincoln Town Car, and 2003-2011 Mercury Grand Marquis — see the Buyer's Guide tab for the full engine-level breakdown.
Signs the original rear track bar may need replacing include a rear end that feels loose or wanders on the highway, side-to-side sway over uneven pavement, or a clunk from the rear when a worn bushing or joint lets the axle shift. If a failed track bar is the cause, this unit replaces it. Diagnose the source of the symptom before ordering, since these signs can have other causes.
