Product Details

TrakMotive AAR CV Axle Shaft FD-8391 is engineered for the front left position on the Ford EcoSport across the listed model years. The AAR CV axle shaft line is identified by application-specific design details, including OE AAR design coverage for 2019 and updated design coverage for 2018, helping match the original driveline configuration where specified. With a compressed overall length of 661 mm (26.02 in), this axle is built to align with the vehicle’s front driveline geometry.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Axle Shaft Helps Address

  • Clicking or popping noises during turns from worn CV joints
  • Vibration felt through the drivetrain under acceleration
  • Torn or deteriorated axle boot conditions
  • Grease leakage from a damaged CV joint assembly
  • Front left axle wear on Ford EcoSport driveline service jobs

Installation Notes

Confirm the vehicle’s build date and position before ordering, especially for the 2020 Ford EcoSport front left application noted thru 10/28/19. Verify spline count, axle nut thread size, and ABS configuration before installation. Use the included axle nut and follow factory torque specifications during assembly.

Quality Assurance

TrakMotive states this AAR CV axle shaft is backed by a limited lifetime warranty. The company also notes ISO 9001:1007 and TS 16949:2009 certification, reflecting controlled manufacturing and quality management practices.
