Product Details

The TrakMotive AAR CV Axle Shaft line is built for direct replacement service in driveline and axle applications. MZ-86037 matches the front left position on the Mazda 3 for the listed model years and uses spline connections at both ends for proper engagement with the hub and transaxle. The thermoplastic boot construction supports joint protection in normal road use, while the included axle nut helps simplify parts matching during repair. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.
