Detailed Description

Delphi TA3379 is engineered as an inner steering tie rod end for the Kia Optima, with fitment covering 2016-2020 models and 2016-2018 Korean-built vehicles. The part number TA3379 is backed by Delphi’s OE development approach, using dimensional and material checks to help match the original steering geometry and installation requirements. Delphi TA3379 also cross-references 57724D4000 for the same application.

Delphi validates steering components under harsh conditions, including temperatures below -40 degrees C and above 120 degrees C, along with extended salt spray exposure. That testing supports durability in demanding road and weather environments while maintaining OE-style compatibility for the steering system.

Common Replacement Reasons

• Loose or vague steering feel from worn inner tie rod components
• Steering play or wandering on the road
• Uneven tire wear linked to steering linkage wear
• Clunking or knocking noises from the front steering system
• Restoring proper alignment after steering component wear

Installation Notes and Tips

Verify inner tie rod length, end gender, and vehicle build details before installation. This part is specified for inner position use on the Kia Optima, and the TA3379 part number should be matched to the vehicle’s steering linkage configuration before service. After replacement, a professional wheel alignment is recommended to restore steering geometry.
