    Default Trailer riding low

    On one side of my trailer my tire has a lot of clearance. On the other side not so much. We are talking about being able to fit my hand in between without an issue to hitting my hand on both top and bottom. It is a 2008 boat mate trailer. Below are two photo's so you can see. Any help on what it is and how to fix it would be great.


    Correct.




    a little low.

    You almost definitely need to have your torsion axle replaced... sorry dude. Contact your dealer or boatmate directly to see if they can help you out.

    Maybe you left the bag full on one side hahaha.


    The torsion axle thing scares me so much that I don't want that to be your problem

    Has it always been that way?
    There is an adjustment that can be made if the torsion is good.

    Guys thank you for the responses. I do not know how long it has been that way. I have never noticed it until it was pointed out. My guess it has been this way for years if not since i purchased the boat in 2008.

    If thats the case, take your wheel off and look at that big nut where the hub assembly attaches to the torsion housing. You can loosen the assembly and rotate it to match the other side. Guys will do this to fit bigger tire/wheels, or to lower the trailer for garage issues.

    Thank you for the help. You do not happen to know the size of the "big nut" and how much to re torque it?

    Old enough to know better, young enough to do it anyway.

    UNIQUE FUNCTIONAL PRODUCTS
    SERVICE BULLETIN

    Subject: Replacement of torsion axle.
    Application: Torsion axle trailers.
    Condition: Rubber suspension element failure allowing trailer tire to contact
    fender.

    Tools Required: Air wrench; torque wrench; Ύ” socket (for lug nuts); 15/16”
    socket and wrench (for axle trailing arm and axle mounting bolts); 3/8” flair
    wrench (for brake lines); floor jack; jack stands.
    If any trailer tire has significantly less fender clearance when compared to the
    other trailer tire(s), axle will have to be replaced.

    To Remove Axle:
    Step 1: Jack up trailer and set on jack stands such that the tires and wheels and
    the defective trailer axle can be removed.
    Step 2: Remove tires and wheels, setting aside the lug nuts, which will be reused.
    Step 3: Remove 5/8” bolt and nut from each axle trailing arm using the 15/16”
    socket and wrench. The bolt must be completely removed. Slide the trailing arm
    off of the splined axle shaft. (Note: If the trailing arm is hard to remove, insert a
    wedge, such as a screwdriver, into the slot of the trailing arm to spread it open
    for easier removal).
    Step 4: Carefully hang the trailing arm from the trailer frame using a wire tie or
    rope. Be careful to not stress the brake line or brake hose.
    Step 5: Remove the (4) 5/8” bolts and nuts that attach the axle to the trailer frame
    using the 15/16” socket and wrench. Slide axle down to clear trailer frame
    brackets and remove.

    To Replace Axle:
    Step 1: Install axle and bolt into the trailer frame brackets. (Note: The axle
    mounting bracket is not centered over the square axle tube. The long part of the
    mounting bracket should be facing toward the rear of the trailer). Torque the (4)
    5/8” bolts and nuts to 150 ft.-lbs.
    Step 2: On BoatMate ski boat trailers, there are only two trailing arm positions
    used. The only axle that is set to 24 (+/- 2) degrees below horizontal will be a
    single axle that has a 15” wheel and five lugs. All other single axles (14” 5-lug
    and 15” 6-lug) and all tandem axles are set to 18 (+/-2) degrees below horizontal.
    Each spline on the shaft moves the trailing arm angle by 6 degrees. If an angle
    finder is available, make certain the top of the axle tube is level and position the
    trailing arm to the correct angle as shown in photo.
    On BoatMate runabout trailers, there is only one trailing arm position regardless
    of axle. This angle is 30 (+/-2) degrees below horizontal. Again, each spline on
    the shaft moves the trailing arm angle by 6 degrees.
    If angle finder is not available, position trailing arm horizontally then move down
    the correct number of splines. Move three splines for the 18 degree setting, four
    splines for the 24 degree setting and 5 splines for the 30 degree setting..
    Slide the trailing arm onto the shaft. . (Note: If you are having trouble installing
    the trailing arm, insert a wedge, such as a screwdriver, into the slot of the trailing
    arm to spread it open for easier installation). Bolt the trailing arms to the splined
    shafts using the 5/8”x 3-1/2” long bolt, washer and nylock nut. Torque bolts and
    nuts to 150 ft.-lbs.
    Step 3: (For brake axle only) Re-attach brake lines and bleed trailer brakes. This
    may not be necessary if the instructions from step for in the Removal section
    have been followed.
    Step 4: Re-install wheels and tires. (Note: If equipped, care should be taken not
    to damage the wheel plastic hub insert). Hand torque lug nuts to 95 ft.-lbs. using
    the every other bolt method.
