Can anyone tell me if the Spicer axle shaft u-joints need to be "clocked"

In other words the splined shaft u-joint at the diff would have the u-joint saddles at the 12 o'clock and 6 o'clock positions and the slip yoke u-joint at the upright would have the u-joint saddles at the 3 0'clock and 9 o'clock positions.

Or do they get lined up in phase?

Thanks for the help.

Cheers
Greg
