Detailed Description

Delphi TA5448 is a rear outer steering tie rod end built for vehicles that require precise steering linkage geometry and stable road feel. It features a straight, adjustable design with a pre-greased internal assembly, a chloroprene rubber dust boot, and a coated steel housing for durable service in demanding undercar conditions. Delphi applies OE-style dimensional and material analysis to help ensure proper compatibility with the original steering setup.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is a strong fitment match for rear outer steering service on 2001-2005 Ford Explorer, 2002-2005 Mercury Mountaineer, and 2003-2005 Lincoln Aviator models, including 2002 Ford Explorer and 2002 Mercury Mountaineer applications with the listed build-date and stud-diameter notes.

What It Helps Fix

• Loose or vague steering feel from worn rear outer linkage
• Clunking or play in the steering system
• Uneven rear steering response caused by worn joint wear
• Alignment instability after steering component wear
• Boot damage that can expose the joint to contamination

Installation Notes and Tips

Verify the rear outer position, thread specifications, and vehicle notes before installation. This part uses a 12.0 mm end 2 thread diameter, 1.75 thread pitch, and a threaded stud design, so matching the original steering hardware and alignment settings is important. After replacement, a professional wheel alignment is recommended to confirm steering geometry and tire wear control.

Quality Assurance

Delphi tests steering components across extreme temperature ranges below -40 degrees C and above 120 degrees C, and subjects parts to 720 hours of salt spray testing. That validation, combined with OE-focused engineering, supports consistent performance for the Delphi TA5448 in service.
