Dana 60 (248 RBI) Axle Description

      The 248 Rear Beam-design Iron (RBI) axle housing consists of a iron center casting (differential housing) with axle tubes extending from the center section sides. The axle tubes are pressed into the differential housing to form a one-piece axle housing.
       The integral type differential housing hypoid gear housing has a pinion center line below the centerline of the ring gear.
       Full floating axle shafts are retained by bolts attached to the wheel hub, which rides on two bearings at the outboard end of the axle tubes. The axle shafts may be removed without disturbing the wheels, hubs, or wheel bearings. The support bearings are opposed tapered roller bearings contained in the hub assembly.
       A removable stamped steel cover provides access for inspection and maintenance of the differential assembly. A small stamped metal axle gear ratio identification tag is attached to the cover by one of the cover bolts. This tag also lists the number of ring gear and pinion teeth.
       The differential case of both the open differential and the optional Trac-lok limited slip differential are one-piece designs. The differential pinion mate shaft is retained by a roll pin. Differential bearing preload and ring gear backlash are adjusted by shims between the differential bearing cones and the differential case. Pinion bearing preload is set by a collapsible spacer (crush sleeve) on the pinion.

      An option Trac-Lok limited slip differential uses a one-piece differential case, the same internal components as the standard open differential, and an additional pair of clutch disc packs, one between each side gear and the differential case, to transfer wheel torque under poor traction conditions.
