Well after I did my saginaw swap I discovered I was still loosing power steering fluid. After some investigating I noticed it was coming from around the pitman arm. I got a seal kit from Ford (D7AZ-3E501-B). Make it easy on your self and get a pitman arm puller and a torch. Mark the pitman arm and steering box before removal so they go back together in the same position.
Here's the offending part. The seals you need to change are around that shaft pointing at the camera.
Here are the kit's contents. Three seals and a snap ring.
Flip the box over and take out the two bolts holding the shaft in place. You'll need a 3/4 inch wrench.
Set the box down on the shaft and it will pop up so you can pull it out.
Pick out the large seal once the shaft is out.
Flip the box over again. You'll probably have to scrape a lot of grime from around the shaft's exit point to find the snap ring ends.
The seal under the snap ring can be pried up. The next one might require you to flip the box over again and knock it out with a screw driver and hammer. Be careful not to scratch any of the surfaces. Once out you don't have to worry about the rollers falling out. There is a metal rim to keep them in.
Here's the order of the seals going in. On the bottom one, make sure the groove with the spring in it faces in.
Both seals and the snap ring installed.
Now on a side note, I took out the other shaft (9/16 inch) out of curiosity and to reduce some of the weight while I was working on it. Mark the position of this shaft's internals so you put it back at the same position. Be careful when the shaft is out. The bottom section can spin all the way off the top section. If this happens, quite a few ball bearings will fall out. Have no fear. The shaft is built to allow them to easily be reinstalled. On the side of this bottom piece you will find a split, horseshoe shaped tube. If you remove the cap over it (3/8 inch) you will see a hole to reinsert the ball bearings.
Now just reinstall and your are good to go!
