Adjust your bars up a bit to put that 220 lbs back on your front axle and off your rear axle. You should never be taking weight OFF your front axle when your bars are hooked up for towing.
When using a weight-distributing hitch, measure distance (1) {ground to top of front wheel opening} before coupling the trailer to the hitch ball. Measure the height again after the trailer is coupled and adjust the spring bars so the distance (1) is as close as possible to halfway between the two measurements.
This implies the front axle load restoration should be about 50%.
The indicated tongue weight of 1160# caused a load of 480# to be removed from the front axle.
Application of WD caused an indicated 260# to be restored to the front.
This gives a front axle load restoration of 54% -- very close to the manufacturer's spec.
Beginning about 2010, Ford, Chevrolet/GMC , Equal-I-zer, and others have abandoned the notion that the WDH must be adjusted to restore 100% (or more) of the load which was removed from the TV's front axle.
