Parts for Dana-Spicer Model 70 Rear Axles in 1980-1985 Ford Trucks and 1980-Up Ford Vans
Ford used Dana 70 and Dana 70HD axles in F350 trucks to 1985.5. In F-Series trucks, Ford Sterling 10.25" rear axles replaced Dana 70 rear axles after 1985. Ford also equipped 1980-current E350 dual rear wheel and some E450 Super Duty vans with Dana 70 or Dana 70HD rear axles
Differential and Pinion Bearings (Individual)
Ford used two versions of standard Dana 70 and and one version Dana 70HD axles in 1980-1985 era 1 ton trucks and heavy-duty van/motor home chassis models. Between standard Dana 70 and Dana 70HD models, the difference is the size of the differential bearings and/or inner pinion bearings. Standard Dana 70 axles have 3-13/16" diameter diff bearing cups. Dana 70HD axles have 4-1/8" diameter diff bearing cups. For 1980-1981, Ford used Dana 70B standard axles or Dana 70HD heavy-duty axles both of which have the same 4-1/8" diameter inner pinion bearing cups. Ford phased out the Dana 70B axles in 1982-1983, replacing it with Dana 70U axles which have inner pinion bearing cups that are 3-1/2" in diameter. Before ordering bearings you need to determine if your Ford has a Dana 70 or Dana 70HD rear axle, plus if your vehicle is a 1982 or 1983 with a standard Dana 70, you also need to know if it is a Dana 70B or Dana 70U

Spindle Nuts and Spindle Hardware
Dan the Gear Man® Tech Note: QU40077 Spindle Nuts and QU40089 Spindle Lock Wedges are "Single Use", genuine Ford and Dana Spicer original equipment components. These parts are designed to be installed once and only once. For safety reasons, you must discard both the nut and wedge if they are removed from the spindle for any reason. Both parts loose a percentage of their resistance to coming off when they are removed. You may hear of cases where this type of factory nut has come off while the truck was being driven. Invariably, these failures involve nuts and wedges that have been reused. I am not aware of a single instance of a properly installed new nut and wedge coming off like that. In my opinion, the original equipment nut design is as safe to use as our double nut sets sold above as long as you follow the rules
