STANDARD PROCEDURE
STANDARD PROCEDURES - ALIGNMENT I.F.S.
Before each alignment reading the vehicle should
be jounced (rear first, then front). Grasp each
bumper at the center and jounce the vehicle up and
down several times. Always release the bumper in
the down position.Set the front end alignment to
specifications while the vehicle is in its NOR-
MALLY LOADED CONDITION.
Camber and caster angle adjustments involve
changing the position of the upper suspension arm
pivot bar (Fig. 3). Refer to the Alignment Specifica-
tion Chart for the correct setting.
CASTER:Move the rear position of the pivot bar
in or out. This will change the caster angle signifi-
cantly and camber angle only slightly. To retain cam-
ber move the forward pivot very slightly in the
opposite direction.
NOTE: For example, to increase a positive caster
angle, move the rear position of the pivot barinward (toward the engine). Move the front of pivot
bar outward (away from the engine) slightly until
the original camber angle is obtained.
CAMBER:Move the forward position of the pivot
bar in or out. This will change the camber angle sig-
nificantly and caster angle only slightly. The camber
angle should be adjusted as close as possible to the
preferred service specification. After adjustment
is made tighten pivot bar nuts to specifications.
TOE POSITION:The wheel toe position adjust-
ment should be the final adjustment.
(1) Start the engine and turn wheels both ways
before straightening the wheels. Center and secure
the steering wheel and turn off engine.
(2) Loosen the tie rod adjustment sleeve clamp
bolts/nuts.
NOTE: Each front wheel should be adjusted for
one-half of the total toe position specification. This
will ensure the steering wheel will be centered
when the wheels are positioned straight-ahead.
(3) Adjust the wheel toe position by turning the tie
rod adjustment sleeves as necessary.
STANDARD PROCEDURE - CASTER
CORRECTION MEASUREMENT
NOTE: To determine the correct caster alignment
angle for Cab-Chassis vehicles the following proce-
dure must be performed.
NOTE: 4x2 11000 GVW has a solid front axle and
uses a 4x4 frame.
(1) Take a height measurement to the center of the
front gauge hole in the frame. Take another measure-
ment to the center of the rear spring hanger bolt
(Fig. 4). Take these measurements on both sides of
the vehicle.
(2) Subtract the front measurement from the rear
measurement and use the average between the right
and left side. Use this number (caster correlation
valve) with the Corrected Caster Chart to obtain the
preferred caster angle.

CAUTION: Components attached with a nut and cot-
ter pin must be torqued to specification. Then if the
slot in the nut does not line up with the cotter pin
hole, tighten nut until it is aligned. Never loosen the
nut to align the cotter pin hole.
CAUTION: Suspension components with rubber
bushings (except stabilizer bar) should be tightened
with the vehicle at normal height. It is important to
have the springs supporting the weight of the vehi-
cle when the fasteners are torqued. If springs arenot at their normal ride position, vehicle ride com-
fort could be affected and premature bushing wear
may occur.
DESCRIPTION
The upper and lower suspension arms use bush-
ings to isolate road noise. The suspension arms are
bolted to the frame and axle through the rubber
bushings. The lower suspension arm uses cam bolts
at the axle to allow for caster and pinion angle
adjustment.

REAR AXLE - 286RBI
DESCRIPTION
The Rear Beam-design Iron (RBI) axle housings
consist of an iron center casting (differential housing)
with axle shaft tubes extending from either side. The
tubes are pressed into the differential housing and
welded. The axles are full-floating axle shafts, that
are supported by the axle housing tubes. The full-
float axle shafts are retained by bolts attached to the
hub.
The differential case for the standard differential is
a one-piece design. Differential bearing preload and
ring gear backlash are adjusted by the use of shims
located between the differential bearing cones andcase. Outboard protective spacers are located
between the differential bearing cup and housing.
Pinion bearing preload is set and maintained by the
use of shims. Pinion height is controlled by a shim
pack located under the inner pinion bearing cup. The
differential cover provides a means for inspection and
service.
Axles equipped with a Trac-Loktdifferential are
optional. The differential contains two clutch packs,
four pinion gears, and a one-piece pinion mate cross
shaft to provide increased torque to the non-slipping
wheel in addition to the standard differential compo-
nents. A Trac-loktdifferential for the has a two-piece
differential case.

CAUTION: Never use gasoline, kerosene, alcohol,
motor oil, transmission fluid, or any fluid containing
mineral oil to clean the system components. These
fluids damage rubber cups and seals. Use only
fresh brake fluid or Mopar brake cleaner to clean or
flush brake system components. These are the only
cleaning materials recommended. If system contam-
ination is suspected, check the fluid for dirt, discol-
oration, or separation into distinct layers. Also
check the reservoir cap seal for distortion. Drain
and flush the system with new brake fluid if con-
tamination is suspected.
CAUTION: Use Mopar brake fluid, or an equivalent
quality fluid meeting SAE/DOT standards J1703 and
DOT 3. Brake fluid must be clean and free of con-
taminants. Use fresh fluid from sealed containers
only to ensure proper antilock component opera-
tion.
CAUTION: Use Mopar multi-mileage or high temper-
ature grease to lubricate caliper slide surfaces,
drum brake pivot pins, and shoe contact points on
the backing plates. Use multi-mileage grease or GE
661 or Dow 111 silicone grease on caliper slide pins
to ensure proper operation.
DIAGNOSIS AND TESTING - BASE BRAKE
SYSTEM
Base brake components consist of the brake shoes,
calipers, wheel cylinders, brake drums, rotors, brake
lines, master cylinder, booster, and parking brake
components.
Brake diagnosis involves determining if the prob-
lem is related to a mechanical, hydraulic, or vacuum
operated component.
The first diagnosis step is the preliminary check.
PRELIMINARY BRAKE CHECK
(1) Check condition of tires and wheels. Damaged
wheels and worn, damaged, or underinflated tires
can cause pull, shudder, vibration, and a condition
similar to grab.
(2) If complaint was based on noise when braking,
check suspension components. Jounce front and rear
of vehicle and listen for noise that might be caused
by loose, worn or damaged suspension or steering
components.
(3) Inspect brake fluid level and condition. Note
that the brake reservoir fluid level will decrease in
proportion to normal lining wear.Also note that
brake fluid tends to darken over time. This is
normal and should not be mistaken for contam-
ination.(a) If fluid level is abnormally low, look for evi-
dence of leaks at calipers, wheel cylinders, brake
lines, and master cylinder.
(b) If fluid appears contaminated, drain out a
sample to examine. System will have to be flushed
if fluid is separated into layers, or contains a sub-
stance other than brake fluid. The system seals
and cups will also have to be replaced after flush-
ing. Use clean brake fluid to flush the system.
(4) Check parking brake operation. Verify free
movement and full release of cables and pedal. Also
note if vehicle was being operated with parking
brake partially applied.
(5) Check brake pedal operation. Verify that pedal
does not bind and has adequate free play. If pedal
lacks free play, check pedal and power booster for
being loose or for bind condition. Do not road test
until condition is corrected.
(6) Check booster vacuum check valve and hose.
(7) If components checked appear OK, road test
the vehicle.
ROAD TESTING
(1) If complaint involved low brake pedal, pump
pedal and note if it comes back up to normal height.
(2) Check brake pedal response with transmission
in Neutral and engine running. Pedal should remain
firm under constant foot pressure.
(3) During road test, make normal and firm brake
stops in 25-40 mph range. Note faulty brake opera-
tion such as low pedal, hard pedal, fade, pedal pulsa-
tion, pull, grab, drag, noise, etc.
(4) Attempt to stop the vehicle with the parking
brake only and note grab, drag, noise, etc.
PEDAL FALLS AWAY
A brake pedal that falls away under steady foot
pressure is generally the result of a system leak. The
leak point could be at a brake line, fitting, hose, or
caliper/wheel cylinder. If leakage is severe, fluid will
be evident at or around the leaking component.
Internal leakage (seal by-pass) in the master cylin-
der caused by worn or damaged piston cups, may
also be the problem cause.
An internal leak in the ABS or RWAL system may
also be the problem with no physical evidence.
LOW PEDAL
If a low pedal is experienced, pump the pedal sev-
eral times. If the pedal comes back up, worn linings,
rotors, drums, or rear brakes out of adjustment are
the most likely causes. The proper course of action is
to inspect and replace all worn component and make
the proper adjustments.

HEADLAMP
DESCRIPTION
Headlamps on the Ram Pick-Up are modular in
design. The turn/park lamp module is incorporated
into the headlamp module. The module contains two
bulbs; a dual filament headlamp bulb, and a dual fil-
ament turn/park bulb. The Sport headlamp module
has two separate bulbs for the headlamp illumina-
tion.
OPERATION
Headlamps and parking lamps are controlled by
the headlamp switch. The multifunction switch
mounted on the steering column controls the high
beam function, and the turn signal function.
