Here is a link describing the proceedure.

Look on pages 5 and 6 on the pdf doc. Your basically removing the lynch pin, making a half turn on the feet that go into the bed of the truck, ( screwing in ) to remove any play, reassemlbing lynch pin, and test install the hitch. I made a few turns untill resistance was felt closing the handles. PM me and Ill give you a call while looking at my hitch if you cant figure it out. You will have to remove your hitch head to do this.
This is the main part... dont loosen the jam nuts, just screw in the feet that lock into the bed of the truck.
6. Insert anchor tee pin through bushing from bottom of base arch and thread into appropriate handle (see Figures 8A and
8B). (With notch in nut facing up and handle pointing toward you, the locking hole is to the right for the left handle and to
the left for the right handle.) Keeping the handle in the unlocked position thread the anchor tee pin into handle nut until
there is metal to metal contact with the bushing. Back tee pin off until parallel with bushing (less than ˝ rotation), then
loosen 1 more full rotation for nominal clearance adjustment (see Figures 8C, 8D, and 8E). At this point the slot in the
handle nut and the hole in the tee pin should be aligned and the lynch pin needs to be inserted and closed (see Figure 9).
Like I said, give me a call. I sent you a PM
