Parts for Dana-Spicer Model 70 Rear Axles in 1973-1991 Chevy and GMC Trucks
We have a good selection of commonly needed replacement parts for Dana 70 series rear axles used in 1973 to 1991 Chevrolet and General Motors 1 ton trucks, vans, van chassis, and motor home models. Dana 70 Heavy Duty (70HD) axles were used in both Single Rear Wheel (SRW) and Dual Rear Wheel (DRW) 1 ton pick and pickup based cab and chassis applications as an alternative to GM 14 bolt 10.5" rear axles. Conventional Van and Panel Van based models may have Dana 70B, 70U, or 70HD axles depending upon the year, Gross Vehicle Weight (GVW), and chassis model.
Axle Identification

1973-1991 Dana Spicer Model 70 Rear Axles in Chevy and GMC 1 ton trucks trucks have either a Bill of Material Number (BOM) stamped on the back side of the right axle tube or a a Build Tag (red arrow) attached to the differential by two of the differential cover bolts (yellow arrows). The BOM number is a 6 digit number beginning with a 6 plus a dash number (ex: 605523-3). They can be used to determine not only the axle model, but also what components the axle was originally built with. We often ask for this number to insure we provide you with the exact parts you need for your truck.

Each different BOM number signifies an engineering part change which may be minor or major and may involve one or more parts. The dash number indicates the axle ratio and differential type (open or locking). Unfortunately, these tags are often missing on trucks that had prior differential service.

GM C and K trucks were not equipped with Dana 60 rear axles after 1972, however, some 1 ton vans did use Dana 60 Dual Rear Wheel (DRW) rear axles from 1973 to 1991 making it imperative that G30 DRW Chassis Van owners identify which axle they have before ordering parts. Not all Dana axles have the model number cast on the housing. It can be very difficult to tell a Dana 60 from a Dana 70, as they have nearly identical covers with exactly the same bolt pattern. One way to tell if you have a Dana 60 or Dana 70 is to measure the cover flange height (yellow arrow). The Dana 60 flange height is approximately 1" high. The Dana 70 flange height is about 1¼" high.

Pinion Seals and Yokes
GM used several different pinion yokes for 1973-1991 1 ton vehicles with Dana 70 series rear axles. While only two u-joint sizes were fitted (1350 and 1410), the yoke and retention hardware will vary depending upon year and model. Replacement yokes and most mid to late production factory yokes use either Spicer type u-bolts or strap/bolt kits to retain the u-joint, however, some axles with 1350 u-joints use GM hardware so you need to verify your hardware type before ordering.
1350 U-Joint: 1.187 cups, 3.625" overall installed width: Verify if GM or 1410 U-Joint: 1.187 cups, 4.187" overall installed width: All we have seen use Spicer type Strap and Bolt Kit

Spindle Nuts and Spindle Hardware
Early GM Dana 70 Full Float Rear Axles in truck applications used a Four Piece Double Nut/Double Washer setup for wheel bearing adjustment and retention. This was used on all 1974-1979 truck axles, most 1980 and some 1981 axles. (The four piece nut set may have still been used on some later 1980's axles for limited applications) Starting in 1980, a single Spindle Nut held in place by a solid Key and Retainer Ring appeared on some models and was phased in for all axles over the next year or two. Both nut types are quite reliable when properly installed. The same nuts were also used on van based models with 2" spindle threads. Link to Our GM Web Page Index
