The AAM 12" rear axles are conventional, integral type housing hypoid gear iron-beam axles with two pinion bearings. The 12" axle was new for the 2019 model year as a replacement for the AAM 11.8" axle used from 2013-2018.
A reusable, right-hand thread single spindle nut is used for rear wheel bearing adjustment and retention. The nut is locked in place on the spindle by a square steel key. A snap ring type retainer prevents the key from slipping out of place.
An o-ring is used to seal between the full-float type axle shaft and wheel hub. The axle shaft is retained by (8) QU11121 bolts with factory applied threadlocker.
The wheel bearings must be packed with grease to provide initial lubrication. In service, 75w85 Synthetic Differential Oil that travels into the wheel hub from the differential will provide long-term wheel bearing lubrication.
The brake rotor is a separate part that bolts to the back side of the hub with 8 bolts.
