• Inner steering tie rod end for steering linkage service
• Straight design with male male threaded ends
• Pre-greased for initial installation readiness
• Steel housing and steel tie rod construction
• Coated finish for added surface protection
• Mounting hardware included
• OE-focused dimensional and material analysis for fit consistency
• Delphi TA6378 cross-references Beck/Arnley 101-7973 for the same application

Detailed Description

Delphi TA6378 is a standard replacement inner tie rod end designed for steering systems that require accurate thread engagement and stable linkage geometry. It features a straight profile, clockwise thread direction on both ends, a 16.0 mm end 1 thread diameter, and a 14.0 mm end 2 thread diameter. The unit uses a steel housing, steel tie rod material, and a POM bearing material to support durable steering operation. Delphi also subjects its steering parts to temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure, to verify material durability.

For 2014-2020 Acura RLX inner steering service, Delphi TA6378 provides a direct-fit replacement option. The part number TA6378 is also useful when cross-checking catalog listings for the same Acura RLX application.

What It Helps Address

• Loose or vague steering feel from a worn inner tie rod end
• Steering play caused by internal joint wear
• Uneven steering response from degraded linkage components
• Noise or clunking from steering system wear points
• Fitment issues when replacing an OE-style inner tie rod on an Acura RLX

Installation Notes and Tips

Verify thread direction, thread diameters, and overall length before installation. The Delphi TA6378 is pre-greased and includes mounting hardware, but the steering system should still be inspected for related wear in the outer tie rod, rack connection, and alignment settings after replacement. Because this is an inner steering component, a professional alignment is recommended after service.

Quality Assurance

Delphi applies OE-level dimensional and material analysis to its steering portfolio and tests parts under severe temperature and corrosion conditions. That validation process supports consistent aftermarket replacement quality for 2014-2020 Acura RLX inner steering applications.
