ball socket type steel bearings contained in the
left end of the right (long) tie rod. The inner-
most bearing seats against a washer which
presents lubricant from filling the right end of
tie rod. A bumper of rolled stock, keyed in
place by the lubrication fitting, forms a spacer
and a lubricant reservoir between the two pairs
of bearings. Heavy coil springs on each side
of the pitman arm ball stud bearings and a
threaded plug in the end of tie rod provide
proper pressure between both sets of bearings
a single screw. The sleeve is locked in place by
a clamp which fits over the slotted end of the
tie rod. During adjustment the tie rod end is
prevented from turning in the sleeve by a large
cotter pin which passes through the shank on
tie rod end into the slots in end of tie rod. See
figure 7-4.

md the ball studs. Flanged bumpers extending
.hrough both springs act as spring guides, per-
nit a restricted movement of pitman arm ball
stud and bearings as the springs absorb road
ihocks, and prevent the bearings from spread-
ng and releasing the ball stud in the event of
spring breakage. The spring tension and the
.learances at ends of bumpers are adjusted by
:he threaded tie rod plug.
The openings through which the ball studs
mter the tie rod are protected by pressed steel
lust covers to keep lubricant in and dirt and
vater out. See figure 7-4.
The tie rod end, which connects each tie rod

a steering arm, is a springload ball stud and

.vhich, in turn, screws into the end of each tie
'00. The tie rod sleeve, which provides for
oe-in adjustment, has a right-hand internal
hread and a left-hand external thread so that
me turn of the sleeve is equal to two turns of
tions which are most likely to be caused by the
steering gear assembly or tie rods. Improper
steering actions which are most likely to be
caused by chassis suspension members are cov-
ered in paragraph 6-11.
a. Excessive Play or Looseness in Steering
System
(1)
Steering gear or tie rods adjusted too
loose or worn (par. 7-5).
(2) Loose pitman arm or loose steering arms.
(3) Front wheel bearings incorrectly ad-
justed or worn (par. 6-15).
(4) Steering knuckle bushings or king pins
worn (par. 6-16).
b. Hard Steering-Excessive Effort Required
at Steering Wheel
(1)
Low or uneven tire pressure (par. 6-8).
(2) Insufficient or improper lubricant in
steering gear or front suspension (par. 1-1 and
1-5) .
(3) Steering gear to frame misalignment
(par. 7-5).
