dierent times on your tow vehicle. First, measure without the trailer coupled.
Next, measure with the trailer coupled, but with no weight distribution.
ird, measure coupled with the weight distribution bars tensioned.
Start by measuring the distance from the ground to the wheel well directly
above the front axle with the trailer uncoupled. See Figure 12. Record this on
LineA of the Weight Distribution Setup Table.
Back the tow vehicle to the trailer and lower the coupler onto the ball. Lock
the coupler and retract the tongue jack until it raises o the ground about 1” so
that the full tongue weight of the trailer is resting on the hitch.
Measure the tow vehicle height again, exactly above the front axle, to the
same point that you measured to earlier when uncoupled. Record this on
LineB of the weight distribution setup table above.
With the tow vehicle still coupled to the trailer, use the tongue jack to
lift both vehicles until you can swing the spring arms into place over the
L-brackets. See Figure 13.
If you reach the top of the jack before the spring arms will swing into
position, you can use the Snap-up Lever to lift the spring arms up and onto
the L-brackets. Use the L-pins to secure the spring arms on the L-brackets. See
Figures 14a -14b.

A Tow vehicle loaded for trip but still uncoupled from trailer 28”
B Tow vehicle coupled but NO weight distribution 30”
Calculate height halfway between A and B (A+B)÷2=
29”
C
Tow vehicle coupled with weight distribution engaged.
Should be at least halfway back to Line A.
Higher than this may still be under adjusted. Lower
than Line A is over adjusted. See Figure 19.
