I was headed up the road last night after taking off from a light. I made it about two blocks, everything seemed fine. Then I lost all power to the wheels (front only, rear drive-shaft is out right now). I gave it some more gas, rev's went up, and so did the spedo reading.
So, Im wondering what could have happened. I went back and checked this morning.
the 4x4 light was out on the dash, but Im wondering if this is because I took it out of 4x4 last night to try to get it rolling again, and putting it back in 4x4 the front vacuum disconnect hasn't engaged yet.
I pulled the vacuum lines off the axle disconnect, and there was no suction when I had the t-case in 4x4. There was however suction at the t-fitting that line goes to on the intake manifold.
My other thought was the clutch wont engage. I checked the reservoir, it is still full. There is no leaks on the master, lines, or slave.
With the transmission in neutral, and the t-case in 4x4, with the rear drive-shaft off, and front drive-shaft connected (but the 4x4 light out), the output yokes from the t-case spin about 1 revolution per 8 seconds. Something strange here, or is this normal if there is no torque load on the driveline?
Not sure why your rear line is off/out, but I'd try in gear power to see if the front shaft is ok, if so, they I'd go back to your vac. system. It is also possible the TC poped into neutral... double check that. Sometime the simplist things are the culpret.

Just have the rear shaft off to get a new one cut and balanced for the new SYE.
I put the tranny in any gear and the front shaft just spins (I believe because the front vacuum is not engaged.)
For the axle disconnect coupling to engage, does the jeep need to be moving, or should the axle-shaft rotate and couple up? and if the jeep needs to be rolling can I try pushing the jeep backwards? Will that be enough force to have it couple back up? I'd like to hopefully eliminate at least one piece of the puzzle and go from there.
