Detailed Description

Delphi TA6409 is a steering pitman arm for Ford Super Duty steering systems that require the specified spline count, shaft diameter, and center link attachment dimensions. It is a direct-fit steering component for 2000-2004 Ford Excursion, 2000-2004 Ford F-250 Super Duty, 2000-2004 Ford F-350 Super Duty, plus 1999 Ford F-250 and F-350 Super Duty configurations listed with monobeam axle or 36-tooth drive notes. This part cross-references 4C3Z 3590-CA for the same application.

Delphi applies OE-focused dimensional and material analysis to help maintain proper steering linkage alignment and fitment. The part number TA6409 is a practical replacement choice when restoring steering response on Ford F-250 Super Duty and Ford F-350 Super Duty trucks, as well as Excursion models with the matching steering setup.

What This Part Helps Address

• Excessive steering play from a worn pitman arm
• Loose or inconsistent steering wheel response
• Steering linkage misalignment at the center link connection
• Wear-related steering correction issues on Ford Super Duty trucks
• Replacement needs after inspection of the steering gear output connection

Installation Notes and Tips

Verify spline count, steering shaft diameter, and center link attachment dimensions before installation. This Delphi TA6409 pitman arm is not pre-greased and does not include a grease fitting, castle nut, or mounting hardware, so confirm all required service parts are on hand before beginning work. Always inspect the steering gear, center link, and related components for wear before final assembly.

Quality Assurance

Delphi tests steering components across extreme temperature and corrosion conditions, including sub-zero and high-heat exposure and extended salt-spray testing, to support OE-level performance expectations. The brand’s OE engineering background and dimensional analysis help ensure strong part-to-vehicle compatibility for the listed Ford applications.
