Like someone tell me in a other thread, I will change my u-joint on my rear shaft.

So, strange question, is it possible to drive without the rear shaft... only with the front one in 4wd fonction ??

I'm not planing to make a long trip !! I just want to know.
 
You'll have to lock the hubs and put it in 4H though, right?
 
yep, no worries, lock hubs, put in 4 high and now you have a front wheel drive Cruiser :)

done it on many a 4x4's
 
What is the difference in driving around without the drive shaft on the rear and putting it 4H and not locking the hubs on the front. I know you are not suppose to drive around in 4H without the hubs locked. Is it because the transfer case just thinks both wheels are spinning with no resistance? Why would this not damage the TC with no rear driveshaft connected? Does the TC just keeping sending 50% to the rear with no resistance?

How is the power distrubed in the transfer case? Does 50% always go to each axle?
 
I have TOWED with a FWD FJ40... :D

I was young (couple years ago) and we needed to take our dirtbikes to the track. My rear driveline was getting rebuilt/blanced by a local driveline shop.

Lock the hubs and go... of course it isn't a long-term deal... the birfs wern't made to pull forever... ;)

No rear driveshaft.. and with the front hubs UNLOCKED... you will go nowhere.. the front drive shaft will spin... the diff will spin, the inners will spin, the birfs will spin, but the hubs will not.

...hubs locked... and you have some FWD action... :D
 
I think his question centered more around the area of why does the manual say not to put the truck in 4h without having the hubs locked? Isn't that the same as driving in 4h with front hubs locked and rear driveshaft gone?
 
I think the problem with driveing with the front drive line engaged with out locking the hubs is that it may cause damage to the hubs. This is not a problem while driving with transfer case in 4wd with hubs locked and no rear drive shaft.
 
DONT DO IT! IT'LL BE THE END OF US AAAAAAAAAAAAAAALLLLLLLLLLLLLLLLLLLLLLLL!


Like LP said, it works. Just remember to be on the ball. That rig will operate differently in all conditions on front drive only.





TB :beer:
 
Is there no center differential? I figured the T-Case also functioned as a center-diff making this impossible. And if it doesn't, then I'd like to clarify a few things. 1st, 100% of power would go to the front wheels, the rear output shaft would spin. Also, locking hubs complete the drive train, the point is to NOT have the front drive parts spining when not in 4WD, as soon as you engage 4WD you are essentilly engaging the front drive shaft, but if you don't hook up the wheels you won't go anywhere. 4HI with the hubs unlocked would probably thrash the drive train since it will have no resistance, and enduce vibrations etc.

There is no real difference, except only the output shaft would be spinning, and it probably won't have any issues like spinning a driveshaft, diff, inners, brifs etc.
