I'm about to do ft. axial u-joint and need to know what size the axial nut is ? thanks. P.S. also what is the torq for the nut? thanks.

 

1 & 11/16 , 180 ft. lbs. a 1 & 3/4 will work in a pinch

 

Careful getting them loose. You may need a 3/4" drive socket and breaker bar. I snapped a 1/2" drive like a match stick getting mine loose for a recent brake job. Of course the 3 feet of cheater pipe may have had something to do with it.
