• Description:

  This is a genuine Ford right front CV axle shaft assembly for the Lincoln Aviator platform, the current service replacement that supersedes L1MZ-3A428-A and Motorcraft TX-1042 in the same family. Fitment covers 20-22 Aviator builds with all-wheel drive, with the inner and outer constant velocity joints, the boots, the clamps, the spline ends, and the inner stub seal assembled into a complete unit ready to install. The shaft transfers torque from the transfer case output to the right front wheel hub, articulating through suspension travel and steering angle on every drive cycle. Owners typically reach for this part when grease is slung across the suspension or inner fender from a torn boot, when clicking under turn indicates an outer CV joint failure, or when the well-documented early-production split-boot complaint demands a current-design replacement axle with the improved boot fold geometry. Important: this assembly ships with several single-use installation components including the axle retention clip, the inner stub o-ring, and the wheel hub axle nut, all of which must be installed fresh and torqued in stages per the Ford service specification rather than reused, since the original fasteners will not preserve the correct bearing preload or seal integrity. Confirm fitment via VIN at order time because the right-side suffix for Explorer and PIU differs from Aviator, and the corrosion protection option further subdivides the catalog. Clean the spline and inner stub seat before installation.
