^ Pinion bearing preload is maintained by a drive pinion collapsible spacer on the differential pinion shaft and adjusted by the pinion nut
^ The axle housing assembly consists of a cast center section with 2 steel tube assemblies and a stamped differential housing cover
^ The differential housing cover uses silicone sealant as a gasket
^ The differential pinion shaft is retained by a threaded differential pinion shaft lock bolt assembled to the differential case
^ The differential case is mounted in the rear axle housing between 2 opposing differential bearings that are retained in the rear axle housing by removable bearing caps
^ Motorcraft 80W-90 Premium Rear Axle Lubricant XY-80W90-QL or equivalent meeting Ford specification WSP-M2C197-A is used in this assembly
