Before giving a test pull to knuckle arm with a
spring balance in the alternative method, in-
stall a large amount of shims on each kingpin to
lighten preload on tapered roller bearing.
Keep on reading the torque, each time decreas-
ing shim thickness a little, and continue this
process until specified torque value is obtained.
(This process protects kingpins because it ensure
that no excessive pull will be applied to bearings
at the onset.) If the process fails to produce
specified torque, that is, if desired torque
resistance does not occur even when shim
thickness has been reduced to zero on each
kingpin, it means that bearings or kingpins are
excessively worn and need replacement.
NOTE:
Read spring balance indication when knuckle
l
arm begins to turn. In other words, you are
to read "starting torque."
When checking knuckle arm starting torque,
l
be sure to have axle hub oil seal removed
and tighten king pin bolts to specified torque.

Upon completion of this check and/or adjust-
ment, be sure to connect tie rod end to steering
knuckle and install oil seal retainer, oil seal,
felt packing oil seal cover and wheel.
Refer to "INSTALLATION" in this section.

Steering Knuckle Oil Seal
The oil seal used at the spherical sliding joint
between knuckle and inner case accomplishes
additional purposes of keeping out road dust
and of acting as the damper for steering hand-
wheel. As wear of this seal advances, its damping
effect decreases and thus makes front wheel
develop a tendency to "shimmy" not onI9 that
road dust begins to creep into sliding clearance
to promote wear of spherical sliding surfaces.
The oil seal is an expendable item, and must be
replaced at regular intervals.

[How to replace oil seal]
1) Remove 8 bolts securing joint seat, and
displace oil seal cover and felt packing inward.
