coupler and close the latch assembly (Figure 72).
Verify that the locking trigger is properly engaged in
its detent.
2. Pull on the ball and/or coupler, trying to remove the
ball from the socket. If the ball moves more than
1/16" in the coupler’s socket, the clamp requires

Hitch Coupler Adjustment
1. With the proper size ball in the socket of the hitch
coupler, close the latch of the coupler completely
(Figure 73). Verify that the locking trigger is properly
engaged in its detent.
2. Tighten the lock nut on the underside of the coupler
until the spring between the nut and the clamp is fully
compressed. Then back off the lock nut 1/2 turn or
just enough that the latch is able to clamp and
unclamp from the ball.
