VI. STEERABLE DRIVE END ASSEMBLY
Spindle Yoke Assembly
Pack the roller bearing with the proper lubricant
and press into place in the spindle yoke. (See
Coat the outside circumference of the outerdrive
yoke seal with liquid sealant. Press the seal into
place in the spindle yoke. (See fig. 36).
Rest the spindle yoke with its inboard side down.
Install the lower kingpin mounting studs.
Lower Kingpin Bracket Installation
Screw the lower kingpin ball stud into the lower
kingpin until it just bottoms. Start the lower
kingpin ball stud jam nut onto the stud.
The lower kingpin brackets with integral tie rod
arms are handed. The left arm goes on the left
steerable drive end and will position the tie rod to
the rear when installed on the axle.
Position the proper bracket on the studs or bolts,
whichever is used., projecting through the
spindle yoke. Install the hardened washers and
locknuts. Tighten to the specified torque. (See
Spindle Yoke to Suspension Yoke Assembly
With the spindle yoke upright , position the outer
drive yoke horizontally. If the spindle yoke
assembly includes the brakes and wheel hub it
should be attached to and supported by a
suitable jack or hoist. Position the lower kingpin
ball (well lubricated) under the lower kingpin
socket in the suspension yoke. (See fig. 21).
The spindle yoke assembly must be tilted
outward at the top slightly to allow the ball stud to
enter its socket.
Raise the spindle yoke assembly until the ball
stud enters the socket. Align the upper kingpin
mounting holes with the corresponding holes in
the spindle yoke.
Install only three bolts. (See fig. 13). The lower
rear bolt is the steering stop bolt. Washers
under the fourth bolts head will limit the
maximum turn angle on the steerable drive end.
The bolts should pass through the camber
adjusting shim or shims. (See fig. 13). The
same number of washers and the same shims
should be reused in a reassembly of parts that
have previously been together. Also refer to
Section IIIll-D and E. Tighten locknuts to
Brake Assembly Installation
Apply a bead of liquid sealant to the spindle
flange or the spindle yoke. See Service Bulletin
738 407, Page 22. Position the spindle on the
spindle yoke piloting on the roller bearing outer
race, aligning the bolt holes, and orienting the
wheel bearing adjusting lock-washer keyway to
face upwards. Position the brake assembly on
the spindle flange pilot, aligning the bolt holes,
orienting the actuator or wedge chamber on the
horizontal centerline at the front.
Install the bolts from the brake spider side, using
hardened washers and locknuts on the inside of
the spindle yoke. Torque to specification
