Applications

Tech Note 1: Parts Availability 
Spicer Dana plastic dial hub parts production ended in 1980-1981 so most parts stocks are now nearly exhausted.  While Spicer hub locks were durable, by now, most 1968-1981 trucks have either been crushed or have had the original Spicer Hubs replaced by Warn 9790 (M248) for Dana 30/44/GM 10 Bolt axles or Warn 11690 (M256) for Dana 60 axles or by aftermarket hubs.  Check the torqueking.com web site for current parts availability.

Tech Note 2: Lubrication
To insure proper hub operation and also protect against corrosion, apply a very THIN film of a quality grease to the internal hub components. Spicer recommended Moly XL hi-speed grease for the internals and Parker "O" Ring Lube (now O-Lube) for the o-rings. Since I did not have ready access to either product, I always used the same grease type as the wheel bearings. The specific grease is probably not as important as the proper quantity. Not enough grease will will lead to both corrosion and metal to metal wear. Too much grease will hinder the locking function of the hubs especially in cold climates.
