    i am new to fords and solid front axle trucks. when i lock both hubs and engage the 4x4 switch and try to do tight turns the truck almost dosent want to move. is it just the u joint or transfer case just wondering if its bad or whats up. found this out before i went to go tear up a field at my buddy's house

    Its you. Don't try turning tight on a dry pavement or you'll blow something out .Start learning how to do 3 pt turns when in 4x4.

    Yup. Like Grandview said. Keep that up on dry ground and you'll see what the inside of your axles look like in a hurry. :(

    No need if you have the shift on the fly. I have never locked mine manually. There might be situations, deep mud maybe where it's prudent, but I've never needed to.

    i heard to keep them clean and greased up and use them a few times so they aren't seized when you need them

    I throw mine into 4high about once every 3-4 months. That's all. But in reality, if the wheel is moving, it's being lubricated. The engagement doesn't change how the grease in the hub works.

    Your truck must have posi trac in the rear if it was limited slip it will turn tight in 4x4

    Not with the hubs locked. My truck is 4.30 posi rear. What the OP is describing is front wheel "hop" caused by the ujoints not being able to fully rotate and the issue being exacerbated by use on dry ground. Has nothing to do with the read end in his case.

    That's why a lot of us plow in 2 wheel drive whenever possible. It's pretty easy to break something when turning sharp on bare pavement.

    If you hubs are lock in and you have a posi trac rear end it will hop realy bad with hubs lock in
    If you have limited slip rear end you will have very little hop in front end
    I have 2 trucks with posi trac and I have 2 trucks with limited slip rear end
    The truck with limited slip will turn easyer on dry ground vs the truck with posi trac with hubs lock in
    What year is your truck has 4.30 rear end

    Any truck will act differently in 4wd on dry pavement, but particularly one with a solid front axle with u-joints. My brand new Ford will buck like a stuck mule on dry pavement if I lock it in, which I wouldn't, since I'm only asking for problems.

    Most of them do. In fact I've never drove one that doesn't.

    That's like saying you have Band-aids, and adhesive bandages. Or Kleenex's, and tissues. Or Coke, and soda. Or Tidy Cat, and cat litter....

    We may need to educate you on the correct category's of differentials and their differences. :drinkup:

    2007 F350 with Towboss package from factory. 4.30 rear from factory. What difference does it make? I'm still right.

    There's a thing in the glove box called an owners manual that tells you not to run your 4x4 on dry pavement due to driveline bind.... Both of my trucks have a warning label on the drivers side sun visor that explains the same thing.

    You need some schooling , a posi is NOT a limited slip and a limited slip is not a locker. Posi is the older way of getting both tires traction then they went to limited slip and now most use lockers. GM first with G-80 locker that engauges automaticly after one tire slips a bit , Ford now has a switch in the cab that you can turn on the locking rear end when in 4x4 . Dodge still has limited slip , so does Toyota but I dont like including them in talk about trucks.

    Technically, positraction IS limited slip, just the GM name for it. There are several different types of limited slip differential, so although the GM positraction may not be the same type of limited slip as the specific type in your mind, it is still a limited slip differential.

    Toyota currently uses two types of differentials in the rear of their trucks; fully open and pushbutton locker (TRD OFFROAD). All limited slip functionality is exclusively via braking. I.e., squeeze the brake on the wheel that is spinning faster. The major advantage to this type of limited slip is that it also applies to the FRONT axle, and can account for steering angle. Effectively, Toyota (and certainly other manufacturers that I'm not as familiar with) have 4-wheel limited slip.

    I'm not sure how this system will react to plowing though. If its cranking the brakes too much, that can't be a good thing.

    Major advantage to electronic limited slip (brakes) is that it can be disabled with the push of a button. Mechanical LSD's cannot be disabled, so if they're continually operating, they'll quickly wear out.
