Being an abuser of axles....... I can safely say that I never broke my Dana 44 rear with 35s and a locker....and it was with standard shafts......
The front was with warn shafts and better UJs .......the more expensive ones......... Yes I broke the UJs but only when at full lock without stops in.......my own fault.....
so........leave the rear as is till you break it...... You won't.........

And carry spares complete inner outer assembled.......for each side at the front.......Tragic does this and it paid off for him at CF last year....... 30 mins off and then back in action.

Tis the cheap and cheerful solution
