    Maybe you guys can fill me in.
    I had trailers with an axle that locked both sides together.
    Now I see a trailer with free wheeling sides. Not locked together with an axle.
    ???

    Are you talking about a steerable lift axle?

    I have seen spread axles on trailers wear each axle can be moved

    Maybe that's what he meant. Front and rear instead of both sides
     
    Bean Jr. Thanks this.

    What would a pic do? A video of one side jacked up. Turning the wheel. Other side against ground.?.?
    Need to rant on about some companies who do not allow U turns. Because you’ll blow tires because they’re locked together. I’ve done that with a heavy load.
    Guessing you people don’t know any more than I do?
    I thought they all had an axle locking both together.

    Your question is confusing. I was even puzzled when I read it and I like to think my comprehension of understanding hard to interpret wording is up there.

    It sounds like you think that trailer axles as in each axle wheel ends should be connected or “locked” the same way a drive axle is locked together with an axle lock? This is not the case and never has been on any trailer axle I am aware of. Trailer axles are idle and always turn at different rates or are free regardless of the axle or suspension type.

    Everyone is just trying to understand your question better so we can understand what exactly it is you’re talking about.

    Trailers don't have axles like drives. Each position turns indepedent.

    Maybe you're thinking of spread axle trailers and not turning too sharp?

    LOL. I've seen Braille that made more sense than your OP
