Product Details

This TrakMotive AAR CV axle shaft is built for the front left position on 2017, 2018, and 2019 Nissan Sentra applications. The NI-8631 is a new replacement axle with an overall compressed length of 27.09 inches (688 mm), designed with 27 inboard splines and 29 outboard splines for the listed fitment. The included axle nut uses a 1.25-inch hex size and M24 x 1.5 thread specification. TrakMotive’s AAR CV Axle Shaft line focuses on application-specific driveline replacement parts for import vehicles, including Nissan Sentra front axle service.

This part cross-references Monroe Shocks & Struts (e.g., 391014AF0C, 391014AF0D) for the same application.

What It Helps Fix

  • Clicking or popping during turns from a worn front CV axle
  • Vibration under acceleration caused by axle wear
  • Grease leakage from a damaged axle boot
  • Noise from worn spline or joint interfaces
  • Loss of smooth power transfer to the front wheel

Installation Notes

Verify front left fitment before installation on the 2017-2019 Nissan Sentra. Confirm spline count, axle length, and axle nut thread size against the original part. ABS axles fit non-ABS applications unless otherwise noted, and this axle does not include an ABS tone ring. Use the included axle nut during service and follow vehicle-specific torque procedures.

Quality Assurance

TrakMotive states that this axle is backed by a limited lifetime warranty and produced by an ISO 9001:1007 and TS 16949:2009 certified company.
