Closed Knuckle Dana-Spicer Model 70 Front Axle Parts for 1958-1978 Dodge 4x4 Trucks

We stock a good selection of axle parts for the Dodge Power Wagon® W200, W300, and W600 Dana 70 Closed Knuckle 4x4 Front Axle. Dodge first used the 4500 pound rated, closed knuckle, Dana-Spicer Model 70 front axle in the 1958 "light civilian" W300. The new W series Power Wagons® were sold concurrently with the military inspired WM300 3/4 ton 4x4. Dodge used the 4500 pound Dana 70 for all W-300 Power Wagons® and some specially equipped W200 Power Wagons® from 1958-1974. The closed knuckle Dana 70 with drum brakes was replaced by a 4500 pound rated, disc brake, open knuckle Dana 60 for the 1975 model year. It is quite possible a few early 1975 model year Dodge W200/W300 were built with the closed knuckle Dana 70, but 1974 is the last year Dodge lists the 4500 pound Dana 70 in Dodge Parts Books.

The short lived 2 ton W-600 medium duty chassis cab truck replaced the W500 1-1/2 ton 4x4 in 1972. Like the W-500, the W-600, at first used the Rockwell FDS750 front axle when it was introduced, but for 1974, two axles were offered depending upon the chassis Gross Vehicle Weight (GVW). The 6000 pound rated, closed knuckle Dana 70 was the "light" axle and the heavy axle was a Rockwell 7500 pound rated FDS75.

The Dana 70 equipped W-600 was only built from 1974 to 1977 when Dodge ceased making medium duty trucks. The last few W-600s built were sold as 1978 models.

Axle Identification
     
     
Dana 70 axle Cover
Click to enlarge 		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.

Closed Knuckle Parts
We stock the regular service closed knuckle parts for your 1958-1978 Dodge Power Wagon® 4x4 with a closed knuckle Dana 70 front axle which will have 12 bolt Knuckle Ball Hemisphere Seals. With a Closed Knuckle axle, the axle universal joints and king pin bearings are lubricated by very heavy oil or a viscous grease that will flow when the axle shafts rotate. A large multi-piece seal is bolted to the backside of the steering knuckle to keep lubricant in and water out. On poorly maintained closed knuckle axles or axles equipped with lockout hubs that are rarely used in 4x4, the upper king pin bearing and axle universal joint can suffer from lack of lubrication. The Ball Seals will usually weep some lubricant especially when standard gear oils are used as a lubricant. Submersion of the axle under water or condensation from temperature changes can cause moisture to build up inside the enclosed ball and lead to corrosion damage and part failures.
