    okay so long story short my front diff hates me and i cant get the passenger side inner axle seal to stop leaking. took it apart and put it back together about 4 times now.
    i have went through 2 new seals so it cant be that....

    i have to use my truck tonight, i was wondering if it was okay to drive it but just not use the 4wd? i can pull my front drive shaft really easy. what do you think? as long as i dont put it in 4wd i would think its fine.

    if i understand the 4wd system right then you would have to pull the cv's for the front diff not to spin

    Sounds a little crazy to me but if you pull both axles and cover the holes somehow, theoretically you can drive it if you don't engage 4wd.

    and i would assume if its not locked in at the hubs the axle wont spin right? so the diff wont spin?

    Unlocked you'll be fine. I actually drove a 91 I had a long time ago with no front diff in it at all for 2 weeks in the middle of a ring and pinion swap. Had the axles duct taped to the horns on the frame where the motor mounts are. It was fine. Would have been a mess had I locked the hubs though. If you've changed the seal twice and it's being installed correctly I would suspect the axle surface the seal rides on is damaged. You may need to swap another axle in.

    Best advice- fix it. If you can afford to have that setup you can afford to have a professional take a look if you've already failed twice. Just my $.02 brother

    sorry I didn't read that you are not talking about a 2nd gen.
    Unlock the hubs and you will be okay not using 4wd.

    I'm pretty sure if you unlock the hubs, the diff won't spin. Easy way to find out is, if you have a go pro, or a willing volunteer, unlock the hubs, keep the truck in 2wd and drive foward. See if the shaft from the front diff to the x-fer case moves at all. If it doesn't rotate as the truck drives ahead, you're good to go (it shouldn't move, there shouldn't be anything driving it).

    If they are spinning that means the inside gears are also spinning even if the diff isnt engaged. Tells me that it would NOT be ok to drive unless you pull the front arms...

    So... why won't you have oil in the differentials? Is it because of an oil seal or some other reason?

    i work on all my own stuff, if i cant do it i usually know someone who can.. next week it will back apart and we will figure out whats wrong.

    but the axles spin?
    thats what i thought, we put it in 2wd and drove forward, the axles spun in opposite directions, one forward one backwards.
    pull the front axles you mean?
    what do i need to do to run in 2wd? pull my axles?
    a seal i think.... we have changed it 3 times and its not doing anything, i dont really understand. this side was fine untill i changed my driver side, once i changed my driver side my passenger side started to leak overnnight, i didnt even drive it.

    I think it's just spinning out of friction. There's no power to it, so if you could grab the front gear by hand, you could hold it still but with those hubs spinning, it's making the shafts spin and then the differential. I don't think removing the front shaft will make any difference. Does your truck have the ADD system or is it a manual transfer case and manual hubs?

    Even if it's a little low on fluid, just spinning will be fine, just keep an eye on it and don't run it dry.
