Step 7: Attaching the trailer to the ball
Using the trailer tongue jack, lower the coupler onto the trailer ball and
close the coupler latch. Do not retract the jack fully at this time. Allow the
jack to support some of the tongue weight.
Raise the front of the trailer and back of the tow vehicle approximately 3"
with tongue jack or until the rear bumper is back to the initial measured
height. This will allow easier installation of the spring bars onto the
support brackets.
Step 8:Installing the spring bar support brackets
Mark the position of the support brackets (#3) by making a center line on
the trailer A-frame a minimum of 4" in from the end of the spring bars
(#2).
Step 9:
Assemble and tighten the mounting plate and bracket onto the trailer
A-frame using two 1/2"-13UNC-4"carriage bolts, two 1/2"-13UNC hex
nuts, and spring washers. Then, assemble the L-shaped bracket onto
the mounting bracket and secure it with two hex nuts and spring washers.
All nuts must have a torque of 45-55ft-lbs. As shown in the following
figure.
