WARNING
Step 3: Mount Ball Plate Assembly
• Measure and mark a point on the trailer tongue 24"
from the center of the trailer hitch ball to the right
side of the trailer frame for #48380 or left hand side
of the trailer frame for #48381 to determine the
location of the Trailer Tongue Ball plate as shown in
Figure 2.
• Align the center of the ball on the Trailer Tongue Ball
Plate with the 24" mark on the trailer tongue and
center punch the six hole locations.
• Drill the six holes using a
11
/
32
" drill bit.
(
Before
drilling make sure the drill will not damage any
electrical wires routed inside the frame.)
• Align the Trailer Tongue Ball with the holes on the
trailer tongue as shown in Figure 3. Install screws.
Step 4: Hook-up Sway Control
• Apply a small amount of grease to both sway
control balls, place socket of slide bar over the sway
control ball and secure with clip.
• Turn the On/Off handle counter-clockwise until the
slide bar can easily slide in the main body. Place the
socket of the main body onto the trailer tongue ball.
Secure it in place with the other clip.
• Turn the On/Off handle all the way clockwise. The
threads should bottom out.
• On some installations, damage to the sway
control may occur during extremely sharp turning
maneuvers. This can be checked by slowly backing
vehicle in both directions into a jackknife position while someone is watching. Make sure that the sway control
does not hit the bumper or trailer frame and that it does not become fully compressed or come apart. If any of
these situations occur when jack-knifed, the sway control must be removed while backing up.
Step 5: Adjustment
• Road and weather conditions, loading and design of the trailer as well as power steering, wheel alignment and the
oscillation point of the tow vehicle and trailer all affect towing characteristics.
• Starting with the factory preset tension, road test the sway control. If this is not enough sway control, then adjust
the brake tension screw ¼ turn clockwise. Road test again and repeat (if necessary) until proper sway control is
achieved. Larger or heavier trailers or broad side trailers may require the use of two sway controls.
• After a 1,000 mile break-in period, remove the slide bar and clean it using a wire brush or steel wool. The slide bar
should then be cleaned every 10,000 miles.
