The Ford owners manual says the below, how does your front end height measurements compare to these instructions?
When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1.
Park the loaded vehicle, without the
trailer, on a level surface.
2. Measure the height to the top of your
vehicle's front wheel opening on the
fender. This is H1.
3.
Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
4. Measure the height to the top of your
vehicle's front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the
weight-distributing bars so that the
height of your vehicle's front wheel
opening on the fender is approximately
a quarter the way down from H2,
toward H1.
6.
Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 2-6.
