Hi Max

From my limited experience with a 1193 on Rob's HUP it seems to act as a spacer betweent he rear and front bearings of the front hub...... so they are part of what is being squeezed and preloaded on the bearings when you adjust the front wheel bearings.......

For all practical purposes the Chev as an identical(probably all Ford made) front unit from the 8 bolt flange outboard.....

which begs to be asked.... if the 1193 spacer is not in place how to the front wheel bearings get adjusted.... what squeezes them together.... what holds the cone bearings tight in place.......

I have a cutaway of the king pin front end and the driven front end of the 4x4.... I will need to study that again to see how it works.....

any other takers.....????
