GENERAL INFORMATION

SUSPENSION
Ram Truck rear suspensions
are
comprised
of;

• Drive axle
• Leaf springs
• Dual-action shock absorbers
• Jounce bumpers (used
to
limit
the
travel
of the
suspension) All
Ram
Truck
and
Ramcharger vehicles
are

equipped with leaf-type rear springs.
The
springs
have
a
one-piece, rubber bushing pressed into their main leaf front
eye.
Model
150 and
Ramcharger
ve­

hicles
are
equipped with
a
fixed-rate type leaf spring. Progressive-rate type rear leaf springs
are
standard equipment
for all
Model
250 and 350
vehicles.

AXLES
The
8 3/8, 9
1/4-Inch
,
Model
60 and 70
axle hous­
ings consist
of a
cast iron center section. They also
have
two
steel axle shaft tubes that
are
pressed into and welded
to the
differential housing. The removable, stamped steel cover provides
a

means
for
inspection
and
service without removing
the complete axle from
the
vehicle. Both axle types
are
equipped with
a
remote vent
fitting. A small, stamped metal axle gear ratio identifica­
tion
tag is
attached
to the
housing cover. The rear wheel anti-lock (RWAL) brake speed sen­
sor
is
attached
to the top,
forward exterior
of the dif­

ferential housing.
A
seal
is
located between
the
sensor
and the
wire harness connector.
The
seal
must
be
in-plaee when
the
wire connector
is
connected
to the
sensor.
The
RWAL brake exciter
ring
is
press-fitted onto
the
differential case against
the flange. A rear axle equipped with
a
Sure-Grip differential
is optionally available
for
both
Ram
Truck
and
Ram­
charger vehicles.
The
Sure-Grip
has a
two-piece case
that
is
interchangeable with
a
standard differential.
A limited-slip differential
is
optional
on
Model
60,

and
70
rear axles.
The
Model
60
uses
the
Trac-Lok
differential
and the
Model
70
uses
the
Power-Lok
dif­

ferential.
The
Trac-Lok differential uses
a
one-piece case while
the
Power-Lok differential uses
a two-

piece case. Both
use the
same internal components
as
a standard differential, plus
two
clutch disc packs.
IDENTIFICATION The axle differential covers
can be
used
for
identi­
fication (Fig.
1, 2, 3).
Model
60
axle
has the
assembly part number
and

gear ratio listed
on a tag. The tag is
attached
to the
left side
of the
housing cover
(Fig. 3).
Build date
identification codes
on
axles
are
stamped
on the
axle
shaft tube cover side.

LUBRICANTS
Multi-purpose, hypoid gear lubricant should
be

used
for
rear axles with either
a
standard
or a
Sure- Grip differential.
The
lubricant should have MIL-L-
2105-B
and by API GL 5
quality specifications.
MOPAR Hypoid Gear Lubricant conforms
to
both
of

these specifications.
In
addition,
4
ounces
of
Hypoid Additive must
be
included with
a
re-fill
for
Sure-Grip differentials.
If
the
rear axle
is
submerged
in
water,
the lu­

bricant must
be
replaced immediately. Avoid axle failure resulting from water contamination
of
the
lubricant.

GENERAL
INFORMATION
A rear wheel antilock brake system
is
standard
equipment
on all AD
models.
It is an
electronically operated system designed
to
retard rear wheel lockup
during periods
of
high wheel slip
and
deceleration.
Retarding lockup
is
accomplished
by
modulating
fluid pressure
to the
rear brake units. Rear brake fluid apply pressure
is
modulated
ac­

cording
to
wheel speed, degree
of
wheel slip
and
rate
of deceleration.
A
sensor located
in the
rear axle
housing converts differential rotating speed into elec­
tronic signals.
The
signals
are
transmitted
to the
electronic brake control module
for
processing.
The

control unit determines rate
of
deceleration
and

wheel slip from these signals.
SYSTEM
COMPONENTS

Basic system components include
an
electronic
brake control module,
a
hydraulic pressure control
valve,
a
speed sensor
and
exciter ring
and an
anti- lock warning lamp (Fig.
1).
A standard master cylinder
and
vacuum power
brake booster
are
used
for all
applications.

ANTILOCK ELECTRONIC CONTROL MODULE
The electronic module controls
all
phases
of
anti-
lock mode brake operation.
The
module
is
separate
from other electrical circuits
in the
vehicle
and
oper­ ates independently.
The module
is
located
on the
passenger side cowl
panel under
the
dash
(Fig.
2).
The

valve, speed sensor
and
indicator lamps
are all in cir-

Isolation/Dump
Valve Cycle Times
Activation (opening/closing) of the isolation and
dump valves is continuous during antilock operation.
The valves cycle rapidly in response to speed sensor inputs and control module signal commands. Cycle
times are measured in milliseconds.
As the demand for antilock mode brake operation
is decreased, the module deactivates the hydraulic
valve components to restore normal brake operation.

ANTILOCK
SERVICE
DIAGNOSIS
GENERAL INFORMATION An antilock system malfunction will be indicated
by illumination of the amber antilock warning lamp.
The red brake warning lamp may also illuminate.
If a problem occurs, system diagnosis should begin
with a fluid level check followed by a visual exami­
nation of the system electrical and hydraulic connec­

tions.
If obvious defects (low fluid, leaks, loose connections, etc.) are not evident, road test the vehi­

cle.
A road test should help determine if a malfunc­
tion is actually related to an antilock component.
During the road test, note if other conditions are
evident such as a low pedal, pull, grab, or similar condition. Remember that brake malfunctions such as low fluid, system leaks, parking brakes partially
applied, will also affect the antilock system. The idea
is to determine if a malfunction is actually related to
an anti-lock component.
If a road test does reveal a problem, repeat the
road test with the owner driving. Make sure the owner is not riding the brake pedal, or has forgotten
to release the parking brakes. Either situation will
generate a fault and cause the antilock light to illu­
minate.

SYSTEM FAULT
CODES
The antilock control module generates flash codes
to help identify the cause of an antilock system fault. Two different control modules are used with the
1992/1993 RWAL system. A type I module is used in
some early production models. All remaining produc­
tion models are equipped with a type II module. The type I and II modules are identified by the way
fault codes 9 and 11 are processed. If the vehicle has a type I module, codes 9 and 11 are not erased when
the ignition switch is turned to Off position. If the vehicle has a type II module, codes 9 and 11 are
erased when the switch is turned to Off.
FAULT CODES WITH TYPE I CONTROL
MODULE
The microprocessor in the electronic control module
has a memory and a self test feature. The self test
feature is activated whenever the ignition switch is
turned to Accessory or Run position. If a system fault is detected, the control module il­
luminates the antilock light and stores the fault code
in memory. Fault codes are retained in memory even after turning the ignition switch to Off position.
FAULT CODES WITH TYPE II CONTROL
MODULE The microprocessor in the electronic control module
has a memory and a self test feature. The self test
feature is activated whenever the ignition switch is
turned to Accessory or Run position.
If a system fault is detected, the control module
will illuminate the antilock indicator lamp and store
fault codes 1 through 8, 10 and 12 through 15 in the
microprocessor memory. When one of these fault
codes is generated, the control module will retain the code after the ignition switch is turned to the Off po­
sition.
When fault code 9 is generated, the code only re­
mains in microprocessor memory while the ignition switch is in Run position. Turning the ignition
switch to Off position erases fault code 9. However, if
the problem still exists when the switch is turned
back to Run position, code 9 will reappear in memory after 20 seconds and the antilock light will illumi­
nate once again.
When fault code 11 is generated, the antilock light
will illuminate when vehicle speed exceeds approxi­ mately 60.35 km/h (37.5 mph). Code 11 only remains in memory while the ignition switch is in the Run
position and the fault is present.
When the cause of a fault code 11 is corrected, the
antilock light goes off. Code 11 is erased when the ig­
nition switch is turned to Off position. However, if
the problem cause still exists when the ignition switch is turned to Run position, code 11 will reap­
pear when vehicle speed exceeds approximately 60.35 km/h (37.5 mph).

FAULT
CODE
CAPACITY
The microprocessor memory will store and display
only one fault code at a time. The stored code can be
displayed by grounding the RWAL diagnostic connec­
tor.

FAULT
CODE
IDENTIFICATION
To determine what the fault code is, momentarily
ground the RWAL diagnostic connector and count
the number of times the amber antilock lamp flashes. Fault codes and typical malfunctions are out­lined in Figure 8. Note that when a fault code is gen­
erated, the red brake warning lamp will also
illuminate. The initial flash will be a long flash followed by a
number of short flashes. The long flash indicates the
beginning of the fault number sequence and the short flashes are a continuation of that sequence.

tension and water pump pressure to force the valve
to open. Coolant leakage into the pellet container
will cause the thermostat to fail in the open position.
Thermostats very rarely stick. Do not attempt to free a thermostat with a prying device.
The same thermostat is used for winter and sum­
mer seasons. An engine should not be operated with­
out a thermostat, except for servicing or testing. Operating without a thermostat causes longer engine
warmup time, unreliable warmup performance, in­
creased exhaust emissions and crankcase condensa­
tion that can result in sludge formation.

CAUTION:
Do not operate an engine without a
ther­
mostat,
except for
servicing
or
testing.
THERMOSTAT OPERATION-EXCEPT DIESEL
The thermostat controls the operating temperature
of the engine by controlling the amount of coolant
flow to the radiator. The thermostat is closed below 88°C (192°F). When the coolant reaches this temper­
ature, the thermostat begins to open, allowing cool­
ant flow to the radiator. This provides quick engine
warm-up and overall temperature control. The ther­
mostat is designed to provide a minimum engine op­ erating temperature of 88 to 93°C (192 to 199°F). It
should be fully open for maximum coolant flow dur­
ing operation in hot ambient temperatures of approx­
imately 104°C (220°F). Above 104°C (220°F), coolant
temperature is controlled by the radiator, fan and ambient temperature.
An arrow plus the word UP is stamped on the
front flange next to the air bleed. The words TO RAD are stamped on one arm of the thermostat.
They indicate the proper installed position.
TESTING-ALL ENGINES The computer On-Board Diagnostics include a
mode for a thermostat open-too-soon failure condi­
tion. The Malfunction Indicator Light (formerly called the Check Engine Light) will not be lit by an
open-too-soon condition. But, if it has failed open, a
Diagnostic Trouble Code (DTC) number 17 will be
set. Do not change a thermostat for lack of heat as
indicated by the instrument panel gauge or heater
performance unless a DTC number 17 is present. Re­
fer to the Diagnosis section of this group for other
probable causes.
The more common type of thermostat failure, usu­
ally found on high milage vehicles, is a thermostat
failed in the shut position. The temperature gauge (if equipped) will give an indication of this condition.
Depending upon length of time that vehicle is oper­
ated, pressure cap may vent. This will expel steam
and coolant to coolant reserve/overflow tank and to
surface below vehicle. Refer to the Diagnosis section
of this group. Also refer to the DRB II diagnostic
scan tool.
On-Board Diagnostics for the 5.9L diesel engine
can be obtained through the DRB II scan tool.
Vehicles equipped with a 5.9L diesel engine do not
have the DTC number 17 malfunction indicator lamp (check engine lamp) feature.
