Detailed Description

Delphi TA3617 is a steering tie rod end designed for inner steering service on Porsche platforms that require a straight, male-threaded replacement component. It measures 242.50 mm in length, with a 206.50 mm stud-center-to-end length, and uses a plastic bearing material with a threaded stud type for secure linkage connection. The black boot color, painted finish, and pre-greased design support clean service replacement in the steering system.

Delphi applies OE-focused testing and dimensional analysis to help maintain compatibility between the original steering geometry and the aftermarket replacement. Part number TA3617 is also referenced in the same application as 991 347 322 00 and EV801207.

What It Helps Address

• Excessive steering play from a worn inner tie rod end
• Clunking or looseness in the steering linkage
• Uneven steering response caused by worn steering components
• Front-end alignment issues related to steering wear
• Replacement needs after inspection reveals damaged steering joints

Installation Notes and Tips

Install TA3617 at the inner steering position only and verify thread direction before assembly. Because steering components affect alignment, a professional wheel alignment should be performed after replacement. Confirm vehicle application by model year and steering configuration before ordering, especially on Porsche 718 Boxster, 718 Cayman, 718 Spyder, 911, Boxster, Cayman, and 918 Spyder applications.

Quality Assurance

Delphi subjects steering components to extreme temperature and corrosion testing, including exposure below -40 degrees C, above 120 degrees C, and extended salt-spray testing. The brand also uses dimensional and material analysis to support OE-style fit and performance in the aftermarket steering portfolio.
