Detailed Description

Delphi TA5503 is an inner tie rod end for steering gear and related components, designed for precise linkage replacement on 2009-2012 Ford Flex, 2010-2012 Ford Taurus, 2009-2012 Lincoln MKS, and 2010-2012 Lincoln MKT applications. It uses a 16.0 mm thread diameter on end 1 and a 14.0 mm thread diameter on end 2, with 1.5 thread pitch on both ends for proper steering connection alignment. The unit measures 320.5 in length and uses a polyoxymethylene (POM) bearing material for the bearing interface.

This Delphi TA5503 tie rod end cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Loose or vague steering feel from worn inner tie rod components
  • Steering play caused by excessive linkage wear
  • Uneven front-end response during lane changes or turns
  • Clunking or knocking from steering gear movement
  • Alignment issues related to worn steering linkage parts

Installation Notes

Verify thread direction, thread diameter, and steering configuration before installation. This part is listed for inner position use and includes mounting hardware. After replacement, a professional wheel alignment is recommended to restore steering geometry and tire wear characteristics.
