Last week my 5000 steering(older model with slave under radiator) started to bind up, and within a short time it completely lost all steering (wheel would just free wheel). I have removed the sector, and it mostly apart now, but having difficulty removing the shaft from the actual box. Is there any special consideration to remove the shaft? I did not take a lot of time last night after getting it torn down that far, and just placed it over a drain pan to drain out good so I could look closer tonight. I am not readily seeing why this happened, but all the 3/8 balls have dropped into the lower portion of the steering box which explains the reason for the free wheeling. Previously I had a large amount of play in the wheel (about 3/4 of a turn of the steering wheel). Any help is much appreciated. I have to admit this is my first experience with the internals of a steering box.
