Detailed Description

Delphi TA5621 is designed for drivers and technicians replacing a worn front inner tie rod end on Infiniti steering systems. The part measures 179.1 mm in overall length, with a 140.5 mm stud-center-to-end length, and uses threaded stud construction with 14.0 mm end 1 thread diameter and 16.0 mm end 2 thread diameter. The black coated finish, steel housing, and POM bearing material support consistent steering operation and OE-style dimensional match. Delphi validates its steering components through extreme temperature and corrosion exposure testing, helping confirm durability in demanding road conditions.

What It Helps Fix

• Alignment instability related to tie rod end wear
• Excessive free movement in the steering rack connection

Installation Notes and Tips

Verify thread direction, thread diameter, and position before installation. This part is for the front inner location and is not adjustable. After replacement, perform a professional wheel alignment to restore steering geometry. Confirm vehicle-specific fitment for 2015 Infiniti Q40 inner, 2010-2013 Infiniti G37 inner, and 2011-2012 Infiniti G25 inner before service.
