Delphi TA3379 tie rod end for the 2016-2020 Kia Optima is a Delphi tie rod, a ball-stud joint in the steering linkage that carries steering input to the wheels.
- Withstands temperatures below -40 degrees C and over 120 degrees C, plus 720 hours of salt spray, in OE-performance testing
- Dimensional and material analysis aims at close compatibility between the OE part and this one
- Includes the necessary accessories for a complete job
- Ball studs are machined to micron tolerances for durability and smooth joint operation
- Fatigue tested to avoid failure
A worn steering tie rod end can show up as loose or vague steering, a knock from the steering linkage, a pull to one side or uneven tire wear. Alignment or tire trouble produces similar symptoms, so with the engine off, look for a torn boot, cracks or leaking grease first, and have a shop check the joint for play.
It is a direct-fit replacement for the 2016-2020 Kia Optima, which takes two. This listing is one tie rod end, and the one on the other side of that axle is normally replaced at the same time.
