Delphi TA3397 Steering Tie Rod End - Left Outer

Delphi TA3397 Left Outer Tie Rod End

Delphi TA3397 is a steering tie rod end built for the left outer position on select Audi applications. It uses OE-based dimensional and material analysis to support proper steering geometry and consistent fit on vehicles such as the Audi Q7, Audi Q8, and Audi A8 Quattro.

• Black finish
• End 2 thread diameter: 16.0 mm

Detailed Description

The Delphi TA3397 steering tie rod end is engineered for OE-style steering performance and dimensional accuracy. Delphi applies the same safety-focused engineering approach used in its original equipment programs, then validates aftermarket steering parts through extreme temperature testing from below -40 degrees C to over 120 degrees C and extended salt-spray exposure. That process helps support durability in demanding road and weather conditions.

This part is a direct-fit steering component for select Audi models, including the Audi Q7, Audi Q8, Audi A8 Quattro, e-tron Quattro, and related performance variants. Delphi TA3397 is also cross-referenced to 4M0 423 811 B and 4M0 423 811 D for the same application.

What It Helps Address

• Loose or imprecise steering response at the left front corner
• Clunking or play caused by worn tie rod end joints
• Uneven steering feel from worn outer steering linkage components
• Front-end alignment issues related to steering linkage wear
• Road vibration transferred through a deteriorated tie rod end
