GENERAL
INFORMATION
STEERING SYSTEM COMPONENTS
Dodge Trucks
use a
power
assisted recirculating-
ball
type steering gear
(Fig.
1). The
gear
is
used with
four
wheel drive
and two
wheel
drive
vehicles. Power steering systems
use;
•
Steering
gear • Steering linkage
• Pressure
and
return fluid hoses
and
fittings
• Belt driven hydraulic steering pump with
fluid
reservoir

Power
Steering
Systems
The steering linkage consists
of a
pitman
arm,
idler
arm, tie
rods,
and
center link. Adjustment
sleeves
are
used
on the tie
rods
for toe and
steering
wheel alignment.
For
additional wheel alignment
in
formation refer
to
Group
2,
Front Suspension. RECIRCULA TING-BALL
POWER
STEERING
GEARS
The recirculating ball system acts
as a
rolling
thread between
the
worm shaft
and
rack piston.
The
worm shaft
is
supported
by a
thrust bearing
at the
lower
end
and a
bearing assembly
at
the
upper
end.
When
the
worm shaft
is
turned
the
rack piston
moves.
The
rack piston teeth mesh with
the
pitman (sector) shaft. Turning
the
worm shaft turns
the
pit
man shaft, which turns
the
steering linkage.
The steering gears
can be
adjusted
and
internally
serviced.
An identification code
on the
upper adjustment
cover designates
the
ratio.
• Code
XS
designates 13-16:1 ratio used
in
Dodge
Ram Truck vehicles
POWER
STEERING
PUMP
Hydraulic pressure
is
provided
by a
belt driven
power steering pump.
The
power steering pump
is a
constant flow rate
and
displacement, vane-type
pump.
The
internal parts that
are
inside
the
housing operate submerged
in
fluid.
The
flow control orifice
is
part
of
the
pressure line union.
The
pressure relief
valve inside
the
flow control valve limits
the
pump
pressure.
The power steering pump
is
connected
to
the
steer
ing gear
via the
pressure hose
and the
return hose.
The pump shaft
has
a
pressed-on pulley that
is
belt driven
by the
crankshaft pulley.
Trailer
tow
option vehicles
are
equipped with
a
power steering pump
oil
cooler.
The oil
cooler
is
mounted
to the
engine block under
the
steering
pump cast aluminum mounting bracket.
The power steering pump
on
the
DODGE TURBO
DIESEL engine
is
bolted onto
the
rear
of
the
vac
uum pump.
The
pump
is
driven
by the
accessory drive through
a
common shaft.

tion refer to Group 8H, Electrical.
CAUTION:
Bumping,
jolting
and
hammering
on the

the
battery
before servicing
any
component
on the
column.
CAUTION:
Do not
attempt
to remove the
pins
to

NOISY OPERATION Transmission noise is most often a result of worn
or damaged components. Chipped, broken gear or
synchronizer teeth and brinnelled, spalled bearings
all cause noise.
Abnormal wear and damage to internal compo
nents is frequently the end result of insufficient lu
bricant, non-recommended lubricants, or improper operation.
SLIPS
OUT OF
GEAR
Transmission disengagement may be caused by
misaligned or damaged shift components, or worn
teeth on the mainshaft gears or synchro components. Incorrect assembly will also contribute to gear disengagement.
LOW LUBRICANT LEWEL
Insufficient transmission lubricant is usually the
result of leaks, or inaccurate fluid level check or re
fill method.
Leaks will be evident by the presence of gear oil
around the leak point. If leakage is not evident, the
condition is probably the result of an underfill condi
tion.
If air powered lubrication equipment is used to fill
a transmission, be sure the equipment is properly
calibrated. Equipment out of calibration can lead to
an underfill condition.
CLUTCH
PROBLEMS
Worn, damaged, or misaligned clutch components
can cause difficult shifting, gear clash and noise.
A damaged pilot bearing will cause noise. If bear
ing damage is severe, drive gear misalignment and
hard shifting can also occur.
A worn or damaged clutch disc, pressure plate, or
release bearing can cause hard shifting and gear clash.
Damaged or worn clutch hydraulic components, or
leaks in the fluid lines or cylinders will cause hard shifting and gear clash. Failure of one of the clutch
hydraulic cylinders can result in incomplete clutch release or engagement.
Verify that clutch components are all in good con
dition before removing the transmission for repair.
TRANSMISSION
REMOVAL—2-WHEEL DRIVE
(1) Disconnect battery negative cable. (2) Shift transmission into Neutral.
(3) Remove screws attaching shift boot to floorpan.
Then slide boot upward on lever. (4) Loosen nut that secures shift lever on transmis
sion stub lever. Then remove shift lever from stub le
ver. (5) Raise and support vehicle.
(6) Mark propeller shaft and axle yokes for align
ment reference. Use paint, scriber, or chalk to mark
yokes.
(7) Remove U-joint clamp strap screws and remove
clamps. (8) Remove propeller shaft.
(9) Disconnect and remove exhaust system Y-pipe.
(10) Disconnect wires at speed sensor and backup
light switch. (11) Support engine with adjustable safety stand
and wood block.
