• Description:

  This is the genuine Ford N1MZ-3A427-E front axle assembly (CV halfshaft) for 21-25 Ford Explorer and Police Interceptor Utility models. Per Eastgate Ford Canada and the Ford catalog dealer catalogs, the halfshaft delivers drive torque from the front differential or transaxle output to the wheel hub via inner and outer constant velocity (CV) joints connected by an intermediate shaft. The assembly is assembled and balanced by Ford and includes both inner tripod-style CV joint and outer ball-style CV joint with factory-greased boots and OEM clamps. Common failure modes include torn CV boots allowing grease loss and contamination ingress (typically the outer boot fails first due to wider articulation range during steering), CV joint clicking on turns indicating joint wear, vibration through the steering wheel at speed indicating shaft imbalance, and shaft splined end wear. Replacement requires removing the wheel, brake caliper and rotor, disconnecting the lower ball joint or strut, and pulling the outer end out of the wheel hub with the appropriate puller. Inner end disconnection varies depending on whether the design uses a circlip retention or bolted flange. Always verify wheel hub bearing condition during halfshaft service since these are common companion failures. This is the genuine Ford service part backed by the OEM warranty.
