Over the entire 15 year production life of the GM 10 Bolt 8.5" beam type front axle, only two hub and rotors were used, a 6 bolt version for 1/2 ton models and a 8 bolt version for 3/4 tons. The hub driving parts however, are a different story. For 1977-1979 Spicer Plastic Dial Hubs were used on trucks with NP205 transfer cases and solid steel hub drive gears equipped vehicles with NP203 full time transfer cases. Spicer hubs came on all 1980 trucks. I believe 1981 models all used Warn M248 plastic dial hubs, but both my memory and the GM parts books are a little vague on the issue. In 1982 GM started using automatic locking hubs. Auto hubs of different designs would continue to be used right through 1991. Warn M248 plastic dial hubs might be found as factory equipment on some work trucks from 1982-1991, but they were also the hub of choice for replacing the often unreliable auto hubs. The auto hub reliability did improve over the years, but a great many of them failed within 5 years. From a durability and reliability standpoint, it is generally best to replace with Warn or other manual hubs, but there is also a monetary value to keeping the original hubs on vehicles of 1982-1991 vintage.

Note about Auto Hubs: There were two different models of auto hubs. We have no parts, but may have some used assemblies. Contact us for availability.
