Anybody ever broke the actuator sleeve in an ADD front end ( http://www.off-road.com/toyota/tech/add/ ) This weekend I may have been a little liberal with the throttle and when the front end came back down, I heard a slow grinding noise and no power to the fronts :whoops: . So after some extensive trouble shooting, 
It seems that the actuator sleeve has a lengthwise crack and whenever torque is applied (ie turning in 4wd or trying to climb) I get a clunk/grind/pop in the front end. In a straight line in 4wd drive no worries until I hit an incline. It seems as though the sleeve is expanding and allowing the axle shaft to spin inside. Anyway, I don''t have an FSM for this rig but its seems prettty straight forward. I'll post pics while I have it apart, but any info on this will be greatly appreciated.
Thanks,
Dan
P.S. I don't feel too bad because a ford 3\4 ton and a Jeep both broke steering knuckles on that same hill
PPS it wasn't the sleeve, it was the ring gear. Now if I could only figure out how to get the darn little gears out of the housing :whoops:
