I went to rausch creek this weekend and after doing my 52's, crossover, and furd towers on the 71, I pulled the front shaft apart twice. It is 27 inches collapsed and 32 extended, thats the measurements from yoke to yoke. I am running one tons and a 205 with cv's front and rear. My local driveline guy found a male slip with about 5 inches of splines, from a carrier bearing shaft but it won't leave enough splines engaged at full droop to survive a 400hp hillclimb. Thats when it tacoed beyond repair sunday, on that last bounce at the top where both front tires are off the ground and the full weight of the tires and axle pulls the driveline to it's max. Articulated it's just fine. I could put in a limiting strap, but where's the fun in that? Maybe one right in the center would work, but not limit articulation too much.
