Product Details

The TrakMotive CV Axle Shaft line is built for driveline service applications that require accurate fitment and OE-style connection points. NI-8525 is specified for the front left side on 2011-2013 Infiniti M56 models, including 2013 Infiniti M56 front left through 2/13. The axle uses a flange inboard joint, spline-style shaft connection, and a conventional outboard joint to align with the original vehicle configuration.

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

Common Problems This Part Can Address

  • Clicking or popping noises during turns from a worn CV joint
  • Vibration or shudder during acceleration from axle wear
  • Grease leakage from a damaged axle boot
  • Driveline noise caused by a failing front left axle shaft
  • Loss of smooth power transfer to the front wheel

Installation Notes and Tips

Verify front left fitment by year and build date before installation. Confirm axle nut thread size, spline count, and overall length against the removed part. Inspect the hub, seals, and surrounding suspension components during service, and replace any worn hardware or damaged mating parts as needed. The included axle nut uses a cotter pin locking design.
