    Re: Excessive sway on 5th wheel

    I wish you would have answered Bill Knights question on sway. I have friend that was complaining of sway and was actually a problem with the truck. He was having problems at the speeds you are stateing and we found a bad universal joint on the truck.

    Sway bars act like dampers that work horizontally. Two sway bars are installed on opposite sides of the trailer hitch and whenever the trailer starts to move to the side, the sway bars, with the help of friction and the brakes of the trailer, will help minimize the amount of sway. Is that right?

    Tire pressures all with the different air pressure has a lot to do with trailer sway from left-right. If the pressures on one side aren't close to the pressure on the other a sway will result at higher speeds.

    One thing I thought of, maybe thereís a suspension issue? Check for flipped shackles or a broken band on a leaf spring?

    Sounds to me like you have side wall flex on the tires.maybe a flipped spring.

    Sway bars are used on bumper pull travel trailers...5th-wheel trailers do not need them.

    The OP with this problem has a 5th-wheel trailer.

    But to answer your question...sway bars on a travel trailer do help to minimize sway.
