    after my blazer (83) spit out the guts to the 10 bolt rear , i went to a 1 ton eaton monster , put in the napa conversion ujoint , well , the drive shaft fit onto the transfer output shaft but i bet there isnt even a inch of contact. so my question is , with a 4 inch lift and knowing i have to retube the driveshaft , how much should the yolk stick out of the transfer case. i bet i have 4 inchs of the yolk shaft showing.

    thanks

    Well, hard to say really, but your suspension should be able to cycle fully (both up and down) without your shaft getting jammed into the t-case or falling out. Don't know what kind of suspension you're running but you may need to go with a fixed yoke and long travel slip-joint shaft.
    You may want to send "drivelineman" a PM with this question, and then have him make you a custom 1-ton CV shaft. /forums/images/graemlins/laugh.gif

    You shouldn't have too much travel coming out of those stock rear springs. I've got 4" rear springs and a stock shaft - there's probably about 2-2.5" of slip-yoke spline contact and I haven't had any problems yet (knock on wood). /forums/images/graemlins/smirk.gif
