Detailed Description

TrakMotive KA-8128 is a front right CV axle shaft engineered for select Kia Optima models, including 2016-2018 vehicles with the updated design and 2019-2020 US-built models identified by VIN 5 as the first digit. This Kia Optima CV axle shaft uses a male inboard joint, conventional outboard joint, and spline connections at both ends for direct driveline replacement. The AAR CV Axle Shaft product line focuses on application-specific fitment and OE-style service characteristics for driveline repair.

Built as a new assembly, KA-8128 includes an ABS tone ring with a 48-tooth toothed design, making it suitable for ABS-equipped applications where specified. The axle nut is included and matches the listed thread, hex size, and locking style for the application. This part cross-references OE-style part numbers such as 49501D4250 and NCV71001K for the same application.

Common Problems This Part Can Address

• Clicking or popping noises during turns from a worn CV joint

Installation Notes and Tips

Verify front right fitment against the vehicle build details before installation.
