STEERING KNUCKLE AND AXLE
PREPARATION
• Clean spindle and axle eyes, wipe dry.
• Remove any burrs from spindle bores and axle
eyes using brake hone or similar device.
INSTALLING BUSHING LIP SEALS
• Handle with care, lip seals are easily damaged.
• Using a bushing driver or similar
device, drive the seals into the
bore leaving the seal fl ush with
the axle side of each spindle bore.
• Be sure to position the seal
so the lip is pointing
towards the axle eye.

SPECIAL INSTRUCTIONS FOR
INSTALLING SPIRAL BUSHING
ASSEMBLY
• Using the STEMCO Kaiser TM bushing driver
specifi cally designed for the kit, drive both
bushings into bores.
CHECK BEFORE ASSEMBLY
• Wipe bushings clean.
• Using king pin check for fi t, fi rst insert pin into
each bushing individually then insert pin into both
bushings, king pin should slide through both
bushings simultaneously.
• If pin fi ts through bushings individually but not
simultaneously the spindle has spread and may
need replacement.
BEARING INSTALLATION
• Prepack bearings with grease.
• For proper bearing orientation refer to fi gure # 1.
• Place needed shims under upper spindle bore.
• Position king pin through upper spindle bore and
through needed shims, be sure TOP of pin is par-
allel to axle for proper lock fl at alignment.
• Place spindle, shims and pin into axle, allow pin
to drop into axle bore about 2”.
• Tap bearing into place, a properly fi t bearing will
require a slight tap fi t without damaging the
bearing case.
• If bearing is too tight or too loose, adjust the
number of shims being used.
• When working on an application where the
bearing has a shoulder, the bearing must be
installed before the shims.
COMPLETE PIN INSTALLATION
• Once the bearing fi t is correct, allow pin to slip
into lower bushing.
• Position lock pin fl ats on pin so they line up with
lock holes.
• Pound lock pins into place, lock pins with threads
apply 25-30 ft. lbs of torque.
END PLATE OR END PLUG
INSTALLATION
• Install end plates or end plugs, using the proper
seal under plates.
• Install grease fi tting into end plate or end plug.
GREASING
• Apply grease until it can be seen between axle
and spindle.
CHECK INSTALLATION
• Once greased the spindle should turn easily from
side to side.
• There should be very little up and down move-
ment.
• If unit seems loose or too tight we recommend
calling our tech line for assistance.
