Detailed Description

Delphi TA6389 is a steering pitman arm designed for the steering gear and related components system on the 1999-2004 Jeep Grand Cherokee. Delphi applies OE-level analysis to aftermarket steering parts, including dimensional and material verification, to support correct interface and consistent performance. The part is tested for extreme temperature exposure and salt spray resistance, helping it stand up to harsh operating environments. If you are replacing a worn Jeep Grand Cherokee steering pitman arm, Delphi TA6389 provides the specified spline count, shaft diameter, and center link attachment dimensions needed for proper steering linkage connection.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Excessive steering play from a worn pitman arm
• Loose or inconsistent steering response
• Steering linkage movement caused by spline or taper wear
• Corrosion-related deterioration at the steering gear connection
• Fitment issues during Jeep Grand Cherokee steering repair

Installation Notes and Tips

Confirm the steering shaft diameter, 48-spline interface, and center link end dimensions before installation. Inspect the steering linkage, sector shaft area, and related components for wear before replacing the pitman arm. Professional installation and a post-repair alignment are recommended after steering component service on the Jeep Grand Cherokee.

Quality Assurance

Delphi uses OE-focused testing and analysis for its steering portfolio, including exposure to temperatures below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray testing. Delphi TA6389 is built to meet the dimensional and material requirements expected for steering service on the 1999-2004 Jeep Grand Cherokee.
