Overview
The Dana Spicer 706395X is a lower king pin parts kit for front Dana 60 and Dana 61 axles, sold for a single side. It bundles the lower king pin seal, lower bearing race, lower bearing, bearing cap and upper king pin seal used with the closed knuckle assembly.
Dana Spicer says closed knuckle and king pin parts like this are hard to find, and that the brand now sells them directly. Treat the universal fit label as secondary to the listed axle types.
Key features

- Closed knuckle and king pin parts for Dana 60 and Dana 61 axles
Knuckle and bearing setup
King pin parts sit inside the closed knuckle and carry the steering load as the wheel turns. Worn bearings or seals show up as stiff steering, a loose feel at the wheel, or grease leaking from the knuckle area. Because the bearings work under load, they are usually replaced as a set with the seals rather than one at a time.
Bearing preload is the critical step. Too much preload binds the knuckle, while too little allows play that wears the parts quickly. Clean the knuckle bore and the cups thoroughly, and inspect the bearing races for pitting. Support the knuckle and axle safely while apart, and keep any shims or spacers in order. Check steering effort and wheel play after assembly, and confirm the seal lips are seated properly.

Installation notes
King pin work means separating the knuckle and setting bearings to correct preload, so a shop with axle rebuild tools is the usual route. Support the knuckle and axle safely while it is apart.
