If the measurement on
line C
is still higher than the calculated halfway point, you
need more weight distribution adjustment (see
line C
on Weight Distribution Setup
Table, Figure 18). With an under-adjusted setup your hitch is not unloading the rear
axle sufficiently, giving back as much steering control as it could, nor is it providing
as much friction as it could to help reduce trailer sway.
To correct under adjustment you must add more weight distribution force to the
hitch by adding spacer washers, or raising the L-brackets.
If this is the initial set up, use the tongue jack to unload the spring bars. Remove
the spring bars from the hitch head. Uncouple the trailer and pull the tow vehicle
forward. Remove the hitch head and add a spacer washer. Repeat step 6 and 7 to
readjust and check weight distribution.
Over or under adjusted weight distribution decreases tow vehicle stability.
Fixing Under or Over Adjustment:
If the hitch is transferring too little or too much weight, you must make adjustments
to the hitch setup. For changes during the initial setup we recommend adding or
removing spacer washers first to try and keep the spring bars parallel with the trailer
frame. This gives you more adjustment options later if needed, and may also reduce
some noise.
Once the maximum (9) or minimum (5) number of spacer washers has been
reached, further adjustments can be made by raising or lowering the L-brackets.
Minor adjustments later for changes in loading can usually be done by moving only
the L-brackets.
The distance from the tow vehicle rear axle to the hitch ball significantly affects
how the tow vehicle reacts to weight distribution adjustments. The same washer or
L-bracket change will have varying results on different vehicles.
Under adjustment
occurs when there is not enough weight being transferred to the
front axles of the tow vehicle. See Figure 24.
