FWIW I went through the whole rebuild ordeal totally blind with the exception of some old guides I found on the net. I got the full rebuild kit (o-rings, teflon rings and roller bearings for around 40 bucks from West Texas Offroad) and everything was fine until it came to the preload. I didn't have an in-lbs. torque wrench or the spanner so I brought the box in to the local GM dealership to have them set it up, I think it was like 25 bucks. However...
To this day I don't know if I did something wrong or the dealership messed up the torque spec but after reinstalling everything and getting the system bled I took it out for a drive. I made two turns and my steering bound up. After pulling the box back out I find it had somehow blown a bunch of the valve body apart and the worm gear got so loose a bunch of the ball bearings fell out the bottom of the power piston.
I ended up bringing the whole oily mess into the local parts shop and going for the reman.
In retrospect it probably would have saved me a ton of money and BS to just buy the spanner and in-lbs. torque wrench.
