Product Details

TrakMotive TO-8429 is a CV axle shaft engineered for front left replacement service on 2016 Scion iA, 2016-2017 Toyota Yaris, 2017-2018 Toyota Yaris iA, and 2018-2020 Toyota Yaris. The axle uses spline connections at both ends, a male inboard joint, and a conventional outboard joint layout to match the listed applications. This part number, TO-8429, is a direct reference for buyers searching for a Toyota Yaris front left CV axle shaft or a Scion iA axle shaft replacement.

TrakMotive’s CV Axle Shaft line focuses on replacement driveline components for passenger vehicles, and TO-8429 follows that product line with a new-build construction and application-specific dimensions. This part cross-references 43420WB002 and 43420WB004 for the same application.

What It Helps Address

  • Clicking or popping noises during turns from a worn CV joint
  • Vibration or shudder from a damaged axle shaft
  • Grease leakage from a cracked or deteriorated boot
  • Excessive play from spline or joint wear
  • Front left driveline failure on the listed Toyota Yaris and Scion iA vehicles

Installation Notes and Tips

Verify the vehicle’s year, model, and front left position before installation. Confirm axle nut thread size, hex size, and locking style against the original part, and inspect the hub, seals, and surrounding suspension components for wear before reassembly. Because ABS axles fit non-ABS applications unless otherwise noted, confirm the vehicle’s brake system configuration and compare the axle length and spline count to the removed unit.

Quality Assurance

TrakMotive TO-8429 is backed by a limited lifetime warranty. The manufacturer states that its products are produced by an ISO 9001:1007 and TS 16949:2009 certified company.
