20. Install the remaining Tapered Roller
Bearing by dropping it down over the hinge
spindle, narrow end pointed downward.
Carefully slide it down the spindle until it is
seated into the upper race.
21. Apply some anti-sieze thread lubricant to
the threads on the spindle. Install the large 1”
Flat Washer next on the spindle, followed by
the 1”-14 Grade C All-Metal Lock Nut. Tighten
the lock nut until it just touches the washer and
bearing, then have your friend slowly swing
the tire carrier back and forth as you tighten
the lock nut the rest of the way. We can not
supply a torque specification for this nut, just
get it as tight as it takes to properly seat the
bearings and provide smooth operation of
the tire swing without any “play”. You may
need to re-tighten this nut several times until
it permanently seats.

22. Install the Hinge Cap O-Ring onto the
outside of the threads of the Billet Hinge
Cap, just under the head of the cap (NOTE:
this may have already been done prior to
shipment).
23. Thread the Hinge Cap onto the Hinge
Housing and lightly tighten with a 2-12”
wrench, socket with ratchet or big-ass
crescent wrench. Note that you may have to
remove it in later steps to further tighten the
spindle lock nut, so don’t fully tighten the cap
until installation is complete.
24. Install the 1/2” Black UHMW V-Alignment
Bushing on to the corresponding bracket
on the Tailgate Plate using the supplied
hardware, as shown in Figure 8.
25. Install the V-Alignment Plate on to the back
side of the Tire Carrier using the supplied
hardware, as shown in Figure 8. Test that it
seats correctly into the V-Alignment Bushing
on the Tailgate Plate when the Tire Carrier
is closed against the tailgate. Adjust as
necessary then tighten all fasteners.

26. Assemble the Aluminum Turnbuckle,
Spherical Rod Ends and SS Nuts into a tie-
rod assembly. Note that there are left hand
threaded and right hand threaded ends of
the turnbuckle, rod ends and nuts, Use the
provided hardware to attach one end of the
tie rod to the Tailgate Plate, and the other end
to the corresponding tabs in the back side of
the Tire Carrier, as shown in Figure 8.
27. Leave the nuts on the tie rod loose, and
adjust the length of the tie rod by rotating
the turnbuckle. Adjust the length so that the
V-Alginment Plate just begins to touch the
V-Alignment Bushing when the tailgate is
about 1/2” from being fully closed and latched,
as shown in Figure 9. This is approximately
the point at which the tailgate begins to
compress the weatherstripping as it closes.
With the tie rod adjusted thusly, test it by
firmly (but carefully) closing the tailgate all the
way, until it latches. When properly adjusted,
this will result in the tie rod firmly pulling the
V-Alignment Plate into the V-Bushing, and
holding it there with enough pre-load to keep
