INITIAL HOOK UP
•Pick reference points on front and rear wheel wells. Measure and record distance to pavement.
Front wheel well to pavement ___________ Rear wheel well to pavement ___________
•Using the tongue jack, lower coupler onto ball and close the coupler latch.
•Install spring bars - orient the spring bar/trunnion assembly with the trunnion reinforcement facing
up as shown in Fig 8. Set the bottom pin of the trunnion into the lower socket of the ballmount and
slide the top trunnion pin into the top slot in the ballmount. Spring bar/trunnion assemblies will fit
on either side.
•Using the tongue jack, raise the tongue of the trailer and rear of vehicle as high as possible and
attempt to set spring bars on top of pad hangers. If bars will not swing over the pad hanger, use of
the lift handle (W) will be required.
WARNING: To avoid serious injury, always stand to the side of the lift handle. Never stand at
the end of the handle or allow any part of your body under the handle.
•Place the lift handle pivot pin in the pad hanger pocket and set spring bar in curved area of lift
handle. Raise lift handle and spring bar should slide on to the pad hanger.
Lower tongue jack. Re-measure the front wheel well reference point. Front wheel well height
MUST be equal to or less than the original measurement. If the front wheel well height is higher
than previously measured, the head tilt angle must be increased (tilted downward). If the front
wheel well height is substantially lower than originally measured (1 ½ inches or more), the head tilt
angle must be reduced (tilted upward), or for coarse adjustment the pad hanger bolts can be lowered
one hole. Spring bars must be unloaded and removed from the pad hangers prior to adjusting head
tilt angle or removal of shoulder bolts. If head angle or shoulder bolt location adjustments are made
repeat hook up steps until the front wheel well height is equal to or less than originally measured.
It’s preferred that the rear of the vehicle settle the same amount or more than the front.
•Optional: The ideal setup would allow the vehicle to settle an equal amount (front and rear) from
the original measurements.
•Swing pad hanger cover (X) over the pad hanger and insert the spring clip. Fig. 10
