1999-2004 Ford F350 DRW Rear Hub
1999-2004 Ford F350 Dual Rear Wheel Trucks with V10 Gas or Powerstroke Diesel engines use the reliable and well proven Dana 80 Rear Axle.
The Dana 80 is a conventional, integral type housing hypoid gear iron-beam axle with two pinion bearings. The pinion is located below the centerline of the ring gear. Ring gear diameter is 11-1/4". Both Conventional (Open) and Limited Slip differentials were offered for the F350. On diesel powered trucks, the differential cover is of finned aluminum construction to help dissipate heat.
The Dana 80 DRW rear axles equipping 1999-2004 Ford F350 DRW trucks have the same size rear wheel bearings as used on most Ford F350 Dana DRW axles all the way back to 1967. Depending upon the year, two different, non-interchangeable DRW rear wheel hubs were used in 1999-2004 F350 Dual Rear Wheel Rear Wheel trucks. Both hubs use replaceable inner and outer tapered wheel bearings. QU40102 right-hand thread ratchet type spindle nut is used for wheel bearing retention and adjustment using special tool number QT1019i. The conventional QU40449 wheel seal also requires a special installation tool (QT1503) to prevent damage to the raised steel seal shell.
An o-ring is used to seal between the full-float type axle shaft and wheel hub. The axle shaft is retained by 8 QU42308 metric bolts with factory applied threadlocker. Reuse of the axle shaft bolts is not recommended by Ford Motor Company.
The Axle Shafts have 35 Splines. There are 4 different Axle Shaft lengths depending if the axle is from a pickup (wide frame) or 34" frame cab and chassis (narrow frame). In addition, the Left and Right Axle Shafts are different lengths for each vehicle type.
The wheel bearings should be packed with grease to provide initial lubrication. In service, 75w140 Synthetic Differential Oil that travels into the wheel hub will provide long-term wheel bearing lubrication. Note: The original factory shop manuals called for a 75w90 oil which Ford has since superseded to a 75w140 synthetic lubricant.
The brake rotor is a separate part that bolts to the back side of the hub with 8 bolts.
