2-4. Raise the tongue of the trailer up high enough so that the ball mount can comfortably t under the trailer coupler.
Back your tow vehicle up so that the ball mount is directly under the trailer coupler and then set the FULL WEIGHT of the
trailer down on the ball.
The front end of your trailer should now be about 1″ to 1-1/2″ lower than the back. If the front of the trailer is MORE
than 1-1/2″ lower than the back, you might need to raise the trailer coupler off of the Ball Housing and move the Ball
Housing up a notch or two so that it is close to level (i.e. within 1-1/2″ difference).
SECTION 1: PREPARATION
SECTION 2: INSTALLING THE RACK AND BALL HOUSING (SWAY CONTROL)
1-1. Start on level ground. If you are planning on hauling ATVs or other heavy equipment, you should load the trailer and
tow vehicle with those items beforehand. Follow proper weight distribution guidelines as laid out in the manufacturer’s
recommendations for the tow vehicle and trailer. Make sure to stay within the limitations of each manufacturer’s maximum
weight recommendations.
1-2. Ensure that the trailer is parallel to the ground by comparing measurements (A) and (B) — i.e. from the ground to the
frame on both the front and back of the trailer.
IMPORTANT! When possible, make sure that any auto-leveling
system is disabled or turned OFF temporarily during installation.
2-1. Once the trailer is level, place the adjustable rack into the hitch receiver
on your towing vehicle. Secure it to the receiver using the standard pin and clip
(provided) or your own locking pin.
(Optional locking receiver pin available from Andersen - Part #3429)
2-2. Place the Ball Housing into the adjustable rack so that the top of the ball is
about 1″ to 1-1/2″ higher than the top of the trailer’s coupler (C).
2-3. Place the two ball housing adjustment bolts through the holes in the rack and
Ball Housing unit to hold it in place (you will tighten the adjustment bolt nuts in step
3-1). At this time, you will want to measure the height of your tow vehicle
bumper (D) for use in step 3-4.
DO NOT GREASE THE BALL OR COUPLER! Since the ball and coupler move together, there is no
friction that would create a need for grease, and any grease that works its way into the ball housing
can decrease the anti-sway abilities of the Andersen WD Hitch.
