There ya go. those fronts are tough as hell. Basically what you need if your runnin a tire over 35" and plan on wheelin it. Pretty expensive. But if ya need one PM me.

a king pin is a 1 1/2" tall cone shaped piece of steel that screws into the inner C. the knuckle sits on top of the kingpin and the spring keeps tension on the knuckle. Its basically a steel ball joint. A kingpin in a big truck is a steel rod that goes from the top of the knuckle all the way through to the bottom and the knuckle hindges on that. Obviously a 4wd truck cant have a 9" rod throught the middle of the C because there would be no room for the axle shafts.

the ball joint axles arent bad. Actually in stock form the ball joint axles are somewhat stronger than the 78-79s because the inner axle shafts do not neck down.
If the u joints and hubs are in good shape you shoudnt have any trouble out of it with 38s and a heavy foot.
