    few things here n there, check out the build
    despite neither tire having contact, wouldn't power go to just one wheel w/ an open diff? and both when locked?

    haha

    When locked BOTH tires rotate the same... 'locked' together.

    The 'open differential' is NOT 'open' when it is 'locked'.

    ONLY if the OP has the locker on, if its not locked then only one will spin (passenger side iirc)

    I know how it works.. was just trying to help the OP determine whether his truck is stuck 'locked' or not..

    Here guys. Jack it up. Put it in NEUTRAL. Turn one wheel with your hand. If the other wheel spins in the OPPOSITE DIRECTION, you have an open diff.

    If the other wheel spins with it, you're somehow connected.

    If you have an LSD I guess it would spin also, albeit at a slower rate.

    Bingo!^^^ I had both my rear wheels in the air and put the engine in gear and gave it throttle and when the diff was open both wheels would spin forward unless I did something to affect one of them, like grab one or start to depress the e-brake. If both tires can spin with equal force they will. It is when one is harder to spin that they won't both spin together.

    If you were locked 24/7 you would know real quick. You get a lot of wheel hop and jerking around when turning in parking lots and such (ie sharply) impossible to not notice this.

    You were right though Cody. haha. Unless the brakes are rubbing or a bearing is bad or something both wheels will turn.

    I have and it would spin both tires unless we interfered with one. I think there is a misconception that open diffs only apply power to one tire all the time. My friend had a nissan frontier that we smoked the rear tires off of. In 1st gear it would roast only the drivers side and in reverse it would only roast the passenger tire (may have been the other way around was several years ago). A lot of vehicles do this (why I don't know actually...) but it leads people to believe that that is always the case. But put the opposite tire in gravel and leave one on pavement and it will spin the gravel one every tire.

    Well guys i went out and jacked up the rear,i did not have the little motor shown and described here. So i feel confident that i do not have have a locking rear end i just have ahole in my dash where they would have put the switch. I do still have double wheel spin n the back im not sure if that means i have lsd or not though as there is nothing on the rear end saying that i can only use lsd fluid.

    even on an open diff... both wheels will leave skid marks on
    pavement or in dirt, as long as the traction is pretty close to
    equal for both wheels when you give it the boot, (and if you are not in
    a turn).... if one was on ice, then the ice wheel will spin up quickly and you'd barely
    start moving

    Well, even my Truck with an LSD will only really "spin" one tire. On pavement, I can spin one tire, while the other one spins regular speed.

    What's happening is that one tire is spinning crazy fast (Let's say my right one) until the LSD kicks in. That makes the other (left) tire kick in, due to the LSD. The left tire will be actually propelling the truck, while the one's that spinning and has less traction continues to spin.

    Depends on how the mechanical LSD is setup. There are several different styles.

    The different types are something I'm well versed in.

    Care to educate me?
