Complete Dereliction of Sense

[1 Lucky Texan]

there were 3 lines, 120* apart, on the inner end of the axle shaft. I assumed it was to help align the tripod joint's 'star'.

there are some youtube videos that speak about phasing or clocking but, doesn't really resemble our axles. And one site I had seen in the past seems unavailable now it was a page called Killing the Clickers. I couldn't even find it at archive.org

 

probably only important at extreme angles.
