    My first of many questions. Thanks for helping me learn.

    When alley docking, should I jack it 90 and do a straight back or a 45 and ease it into the block?

    I'm thinking if I'm light, a 90 and straight back would be fine. But if I'm at 80k loaded on a non-gravel lot, wouldn't I risk the chance of blowing a tandem tire or breaking a spring hanger or shackle?

    When would it be ok to do a 90 and straight back?

    Thanks in advance.

    The shallower you can turn, the less wear and tear you put on everything

    Spread or tandem axles?
    Tandem, no problem. Spread, bad news.

    If a 10 ft. Spread axle can do it. Not recommended though.

    A closed axle shouldn't have any problems.

    When you get to a 90 degree angle your trailer can tilt causing damage to the truck and trailer.
    When your at that angle the 5th wheel can tilt forward or backward causing damage as the trailer will roll with the movement of the 5th wheel. Especially if your on a hill and there is weight on the front of the trailer

    I've done it before

    Notice the trailer wheels when doing a "90". They are binding, big time. This my friend is not good . Sometimes it must be done, there is no other way. Like curbing your tires, sometimes. (that breaks down the sidewalls)
     
    Flankenfurter Thanks this.

    Watch many company drivers (and container haulers come to mind) take pride and pleasure in spinning a truck around, hard as they can, digging holes with trailer.
    Deliver to a small three dock place. Every truck comes in, blows a hard U turn and backs into dock. I show up, looking like grandpa, do a three point turn and back to dock. I don't get turned on ripping trailer suspension/tires off trailer.
    The yard man thanks me every time.

    Thanks all. So far, I'm hearing, "Forget it" unless you care. I just don't want to land in a shop with a flat or suspension trouble. A 90 turn seems easier than a 45. Takes up less room and gets you in faster.

    Are you in a competition to see who can get into a dock faster? Everyone is saying don’t jack the trailer around hard, keep doing it the “easy” way if that’s all that matters to ya.
