8.
Remove the jack or hoist supporting the brake
drum. Using a pry bar under the upper kingpin
bracket, 1/32 to 3/32 play may be observed on a
new assembly. After loading, up to 1/8 play is
acceptable. More than this requires inspection
for wear or distortion.

The kingpins should be readjusted after any
loosening or removal and reassembly of the
upper or lower kingpin brackets, replacement of
kingpin bushings, etc.
D.
Steering Stop Adjustment
1.
Adjust the tie rod. See section III-G.
2.
Steering stop adjustment is made at the factory,
needs no further action unless a major part such
as the suspension yoke, spindle yoke, kingpin
bracket or the like has been replaced.
3.
The steering stop is the lower rear, upper kingpin
bracket mounting bolt (See fig. 7).
Adjustment is made by the installation of a
number of washers under this bolt’s head (See
fig. 8). The purpose of the stop is to protect the
universal joint and the brake chamber from
hitting another part in a full turn of the steering.
Fig. 8
4.
Turn the steering to put the axle first in the full
left turn condition. (See fig. 9). The head of the
stop bolt should stop the turn before any of the
rotating parts in the left hand steerable drive end
interferes with another part. The brake chamber
on the right end should not hit the suspension
yoke. Turn the steering to the right and check
the corresponding conditions (See figs. 8 and
10).
NOTE: POWER STEERING STOPS IN THE
VEHICLE STEERING GEAR SHOULD NOT
ALLOW THE APPLICATION OF POWER TO
THE STEERING WHEN THE STEERABLE
DRIVE
END
IS
IN
THE
FULL
TURN
CONDITION.
