If ether drive shaft is removed or any gear, axle, birf, etc, is broken it will cause slippage and park will not hold.
To lock without the switch: With the key turned to run, shift low range to lock the center, remove the Diff fuse, shift high range and drive. When you want to unlock, simply replace the fuse.

why would u "need" new front driveline becuz of vibration.
how do your u-joints look....no play??..play?

It might be because the noise that he mentioned, went away after removing the drive line.
dont you know how to use the park brake

Well, the truck is lifted about 4 inches or so, and the castor is better then factory which puts quite a bit of stress on the driveline from what i have read. Noise didnt happen until i lifted it. I remove the driveshaft, noise is gone. Hence me thinking i need a new driveline. Not the SAME one but new, i mean the taco shaft.
Agreed
Whats an even better question is say for example the ebrake wasnt set, and it rolled out into traffic. Now just say it rolled through a green light as someone was running a red light. Guess who gets that ticket????
That sucks
Yes, this is a known bit. With any one wheel in the air, parking brake off, transmission in Park, these trucks can roll right off the jack stands.

In your scenario - I understand how it will roll if put in Park with the front shaft missing and the CDL off. What I don't get is how it moves anywhere in drive with no shaft and no CDL without roasting the hell out of a VC - but yours seems to be too old to have a VC...
I see now - you didn't state your model year. You're likely doing some serious damage to the Viscous Coupling in you '95-'97 Land Cruiser by driving with the front shaft out and the center diff disengaged.

I have never put any vehicle in Park without setting the Parking brake (first) and never lifted any part off the ground without chocks... Better to make a habit out of it and never be surprised.
(Unlike the parking brake for some other people in my household who should better stay unnamed to protect the guilty...

True for any car or truck. A front wheel drive will roll if one front tire is lifted, a rear wheel drive if ether rear is lifted.
OK, but I don't count on the e-brake, as long as the tires are on the ground, park is much stronger. The e-brake is kinda OK on flat ground, but with any slope, the rig will still roll off of the cliff, just slightly slower than without the e-brake.
^^^ This applies to any vehicle. They don't need to be anything fancy, rock, hunk of wood, jack stand laying on it's side, whatever you have handy is much better than nothing.

Another quick question. Why wouldnt my center diff. lock light come on? It used to work about 2 months ago. I did the 7 pin mod and added the hazard switch for the cdl but the light doesnt come on.
I pulled the dash and replaced the cdl bulb with a new bulb and the light still wont come on. anyone know what i should start with next???

reverse your pin 7 mod. You might have done that wrong and clipped the wrong wires.
Exactly - but for some reason people seem to assume that since this is an AWD vehicle that if you put it in park the other 3 wheels will keep it from going anywhere.
Park only works if all drive wheels have traction.
Now, as to the OP's Center Diff - Is it possible to fry the Viscous Coupling bad enough to where it will no longer properly engage the diff lock - or are they far enough apart that it shouldn't matter?

My center diff is locked. THe truck doesnt move at all without it locked.
My issue now is there is NO light on the dash for the center diff. It worked a few months ago, the bulb is good. I dont really know where to start next.

the Park pawl is not inspiring much confidence in me... tiny piece of metal that holds the entire weight of the car? and what happens to the pieces if it breaks?
now admittedly I don't remember reading about any breaking...
but my Parking brake is pretty good, it'll even hold the truck with the engine running at a good clip IIRC.

Did the abs light ever come on?

Nope, the abs light never came on.
Update though.
I took the diff lock light actuator off, tested it. Tested ok. Cleaned it up pretty good, put it back in and the cdl light comes on and so does the abs. So thats good to go.
I also got a tacoma shaft coming.....
Good times. I love this thing.

because you confirmed that the center diff was locked but no lights in the dash this is likely the sensing switch on the t-case and not a bulb.
