Mevotech Supreme Steering Idler Arm P/N:MS50924
Help keep your steering linkage steady and responsive with the Mevotech Supreme idler arm, part number MK5143. This front steering component uses patented sintered bearings and includes a serviceable grease fitting. It fits many vehicles, among them the 1964 Chevrolet Malibu, 1964-1972 Chevrolet Chevelle and 1968-1972 Chevrolet El Camino, as a direct-fit replacement for the listed applications.
A steering idler arm supports the end of the center link opposite the pitman arm. It pivots with the linkage to hold the link level as the front wheels turn. If wear in the original arm is causing loose or wandering steering, this arm replaces it.
Signs that an idler arm may need replacing include excess play in the steering wheel, wander on the road, a clunk when turning and uneven front tire wear. Diagnose the cause before replacing parts, and have the front-end alignment checked after installation. See the Buyer's Guide tab for the full list of vehicles.
