shortening drive shaft

[MancheKid86]

getting my drive shaft shortened tomorrow,

i measured 50" u joint to u joint needed,

this is with the slip yolk almost flush with the end of the transfer case,

should i make it 49" for flex? (as in axle sliding in towards the x-fer case while crawling?)

or should the 50" be good?

will the drive shaft only slide out while flexing?

 

 

input would be great.

Your yoke should have a wear mark where it was riding at the seal originally..........that's from where I measured mine.

 

Yes the yoke needs the flexibility to move in both directions.

The driveshaft will only slide into the tcase on axle droop, and only minimally. I would position the yoke in the middle of its travel, or even a little further in the tcase and then measure.
