Product Details

TrakMotive’s AAR CV Axle Shaft line focuses on OE-style driveline replacement parts with application-specific dimensions and connection styles. NI-8726 is engineered for front-right use on the Infiniti QX50 and Infiniti QX55, including the 2019 Infiniti QX50 updated design with a 1003 mm compressed length. The axle uses spline connections at both ends, a conventional outboard joint type, and a neoprene boot to help maintain joint protection in daily driving conditions.

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

  • Clicking or popping during turns from a worn outer CV joint
  • Vibration or shudder from a damaged axle shaft
  • Grease leakage caused by a torn CV boot
