INSTALLING THE PreSet
Plus WHEEL HUB
ASSEMBLY
Failure to fill the hub with the correct amount
of lubricant can cause premature failure of the
PreSet Plus hub assembly, which, if not avoided,
could result in death or serious injury.
WARNING
!
Use the proper hubcap for the type of lubricant
intended to be used.
NOTE
1. Clean the spindle to remove
any lubricant, corrosion
prevention coating, foreign
material, or surface rust that
may be present.
2. Lubricate the bearing journals
on the spindle, or the inside
diameter of the bearing cones
with Grade 2 grease or the
lubricant that will be used in the
wheel end. Do not coat the seal
journal on the spindle.
3. Lubricate the inside diameter of
the seal with the same lubricant
that will be used in the wheel
end.
4. If present, remove the red
locking snap ring from the
spindle nut. Verify that the
bearing spacer is in proper
alignment. Align the key or flat
on the washer with the keyway
or flat on the spindle as the hub
is placed onto he spindle. Use
a smooth firm motion and place
the hub onto the spindle. When
the threads on the nut engage
the threads on the spindle,
rotate the nut in a clockwise
direction to fully engage the
threads.
5. Torque the spindle nut to the
following torque values:
-
Steer Hub – Torque the
spindle nut to 300 ft-lbs while
rotating the hub. DO NOT

6. Visually examine the three
holes in the face of the spindle
nut. One of the holes will line
up with the holes in the inner
washer. Install the tab of the red
locking snap ring through the
hole in the nut and washer that
are aligned. Spread the locking
ring, push it over the spindle nut
and in to the machined grooves
in the spindle nut. Use caution
not to bend the locking ring
permanently. If the locking ring
is damaged or bent, replace it
with a new one.
7. Install the hub cap or drive axle
with a new gasket. Torque the
hub cap bolts in a star pattern
to 12 to 18 ft-lbs. Torque the
drive axle bolts or nuts per
the drive axle manufacturer’s
recommendation.
