STEERING KNUCKLE AND AXLE
PREPARATION
• Clean spindle and axle eyes and 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
flush 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 PRESIZED BRONZE
BUSHINGS
• Using the Kaiser Plus bushing driver specifically
designed for your kit, drive both bushings into bores.
CHECK BEFORE ASSEMBLY
• Wipe bushings clean.
• Using king pin check for fit, first insert pin into each
bushing individually then insert pin into both bushings,
king pin should slide through both bushings
simultaneously.
• If pin fits through bushings individually but not
simultaneously the spindle has spread and may need
replacement.
BEARING INSTALLATION
• Prepack bearings with grease.
• For proper bearing orientation please refer to figure #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 parallel to
axle for proper lock flat alignment.
• Place spindle, shims and pin onto axle, allow pin to
drop into axle bore about 2".
• Tap bearing into place, a properly fit bearing will require
a slight tap fit without damaging the bearing case.
• If bearing is too tight or too loose, adjust the number of
shims being used.
COMPLETE PIN INSTALLATION
• Once the bearing fit is correct, allow pin to slip into
lower bushing.
• Position lock pin flats 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 fitting 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 movement.
• If unit seems loose or too tight we recommend calling
our tech line for assistance.
