Ok. Top 2 pics show a closed and open knuckle front. The knuckle is the part that moves. Inside your closed knuckle is a u joint just like one in the open front. This joint transfers power out to your hub when in 4 wheel drive. The u joint connects the iner and outer shafts. The outer shaft goes through the spindle. That is the rusty part pictured last. The spindle is bolted to the knuckle and also is how the brake backing plate is attached . Next the cutaway pic shows an early internal spline hub drive flange. If you look where the dust cover snaps in there is a groove. In this groove you have a snap ring that holds the outer part of your hub. You then can remove that hub part. Then you will find a smaller snap ring that holds the inner hub part on the outer axle shaft. Then deep in there you will find a spindle nut a lock ring and another spindle nut. WARNING A SPECIAL SPINDLE NUT SOCKET IS NEEDED. The other diagram shows the bearings and spindle and knuckle. I also put a diagram of a later internal spline hub. While the hub parts look different than yours the two snap ring are the same. Well I need a break. Next we will discuss more about this job. Barry
