driving without front shaft

can i drive my np231j trans case without a front shaft? Need to see where my vibes are coming from front or rear. If I can, how long? I searched but I missed it or I'm blind. The front shaft has play in the slip joint. How much is to much?

Thanks in advance

You sure can, I've been without one for a couple months. You get slightly better gas mileage that way as well.

yeah same here, i had some bad vibes after doing my 2wd to 4wd conversion. especially at highway speeds....took out the front and the vibe went away....good luck with that....

Thanks for the quick response. I really appreciate it. Gonna take it off and rebuild it but need the jeep for dd.
