CHRYSLER SERVICE MANUAL
d. Hissing Noise Accompanied by Loss of Oil
Through Vent in the Upper Housing
(Left Turn Only)
This may be caused by oil leakage by the upper
piston rod housing head oil seal. Disassemble
and inspect for: damaged housing head (upper
piston rod) oil seal; seal not seating properly
in the housing head; upper piston rod for
scratches which could permit leakage by the
seal, and seat seal in the housing head for nicks,
burrs, etc., which would prevent the seal from
seating properly. Replace seal.
e. Creaking Noise (On Turns)
This noise may be detected while turning in
either direction and can be caused by loose gear
to frame mounting bolts. Tighten bolts and
recheck for noise. If the noise continues, install
the latest type of new gear shaft. Shaft can be
installed without removal of the unit.
f. Snapping Noise
This noise is usually intermittent and can be
produced when the direction of the steering
wheel is suddenly reversed. Inspect for loose
steering gear to frame bolts. Tighten and
recheck for noise. If the noise still exists, check
front suspension for springs not being properly
seated; camber adjusting bushing set screw
being loose; center link and tie rod joints for
alignment; brake supports, and spacer washer
on brake shoe anchor biting into support, etc.
In some rare instances, the noise may be
caused by one of the following items: lower
piston rod bushing dowel pin being too high;
foreign material preventing bushing from seat-
ing, and bearing surface of bushing rough.
Install a new bushing, if necessary, making sure
it is seated in the gear housing and that the
head of the dowel pin is slightly below the bear-
ing surface of the bushing. Inspect for the lower
piston rod being loose in the piston. Replace
parts, as necessary, to assure a tight fit.
g. Chuckle Noise
This noise is most noticeable when the car is
driven over rough or choppy roads and is usu-
ally accompanied by road wander. The condition
*nay be caused by one or more of the following.
Check in the following order:
Steering gear arm nut loose on the gear shaft,
Tighten to 100-120 foot-pounds torque.
Loose front wheel bearings. Adjust bearings.
Gear shaft adjustment too loose.
Excessive king pin end play. There should be
.006 to .008 inch clearance between the steering
knuckle and the knuckle support. Adjust clear-
ance through the use of shims as needed.
Steering tube coupling screw loose.
Worm bearing pre-load adjustment too loose.
Adjust pre-load.
Excessive worm shaft end play in connector
assembly. Replace worm and connector as an
assembly.
h. Looseness, Shake or Roughness at Upper
End of Steering Column or Steering Wheel
This noise condition may be caused by improper
assembly of the upper column jacket bearing.
The prongs of the jacket should be staked over
the outer bearing race so that the distance from
the end of the jacket to the upper or outer sur-
face of the staked prong is .08 inch, or approxi-
mately %
4
inch. If the bearing is not assembled
properly, the column bearing spring is not
loaded sufficiently and causes one of the above
conditions.
29. IMPROPER STEERING
a. Wander (Steering Wheel Free Play)
To determine whether or not this condition is
caused by the Power Steering unit, proceed as
follows: With front wheels in the straight-ahead
position and resting on the floor, start engine
and, with a very light touch, move the steering
wheel to check free play. Free play should not
exceed % inch. It requires careful checking to
determine the exact amount of steering unit
free play without any movement of the steering
linkage. If it has been accurately established
that the free play exceeds % inch, the cause
may be one of the following:
Gear shaft adjustment too loose.
Steering tube coupling screw loose.
Worm bearing pre-load adjustment too loose.
Excessive worm shaft end play in the con-
