INSPECTION OF COMPONENT
Stabilizer and its Bush
Inspect stabilizer for damage or deformation.
If defective, replace.
Inspect bushes for damage, wear or deteriora-
tion. If defective, replace.

Barfield Joint
To be checked on this joint is its axial play,
which shows up when a push-and-pull motion is
given to live axle shaft and wheel spindle held in
both hands, as shown in figure. There should be
no play at all but a play of up to 1.5 mm (0.06
in.) is permissible. If play exceeds service limit,
replace it.
\/
Leaf Spring Bushes
Inspect for wear and breakage. If found defec-
tive, replace.
Front Wheel Bearing
Check front wheel bearing rollers for damage.
If anything is found wrong, replace bearing with
a new one.

cracking, distortion or any other damage.
Replace the kingpins found in defective condi.
tion.
Check the oil seal for wear or damage. If defec-
tive, replace with new one.

Steering Knuckle Oil Seal
The oil seal used at the spherical sliding joint
between the knuckle and the inner case accom-
plishes the additional purposes of keeping out
road dust and of acting as the damper for the
steering handwheel.As the wear of this seal
advances, its damping effect decreases and thus
make the front wheel develop a tendency to
“shimmy”not only that road dust begins to
creep into the sliding clearance to promote the
wear of the spherical sliding surfaces.
