The front axle has some good news, and bad.

I sandblasted, then primed it. Once I pulled the differential cover, I discovered the first challenge. The spider gears were missing some teeth…

I ordered some parts from Walcks, then quickly studied up on how to take the axle apart. It's really is amazing how simple this axle is.
I removed the axle retainers. This allows you to pull the axle shafts out of the axle housing. I then removed the king pins.
I removed the old axle seals and pulled the knuckle housing off. I cleaned everything up. This is when I discovered the next problem…

These are the king pin bearings. They are toast. There were no king pins shims, thus no proper preload. Clearly, replacement bearings need to be ordered.
The axles and knuckle bearings look new, along with these bearings and cups…

It’s strange to find many parts in ‘like new’ condition, and others that are broken and neglected.
Time to re-assemble this axle. This is such a greasy job. It’s hard to take photos of the process. I removed the ring gear from the carrier. I removed this pin…
This is when I discovered that the ring gear and carrier had to be removed from the housing before I could get at the spider gears. Once out of the differential housing, the
large retainer pin will slide out, releasing the spider gears. I pulled the old gears out, then slid the new set in without any difficulty. I re-inserted the pins, greased up the bearings and cups, re-installed the ring gear, then reset the carrier into the differential housing. I tightened the bearing caps to spec….


Time to set the new king pin bearings. I greased them up real good, then slipped the knuckle housing into position. I have the old style knuckle housings, so I need to add shims to both the upper and lower king pins. There was quite a bit of trial and error. I had to installed and remove the king pins four times before I reached the proper preload. I settled on 10 lbs of pressure with a fish scale. You would think the other side would need the same amount of shims. Not in my case. I had to set, then remove the other side three times before I reached my goal.

I installed the new knuckle seals, then slid in the axle shafts. I temporarily reset the axle retainers until I’m ready to install the brake backing plates. This repair took me longer than I thought it would. 6 hours. This included the cleaning. I hate cleaning.
