TOWING
RECOMMENDATIONS
When it is necessary to tow a Ram Truck, the rec­
ommended method is either:
• the sling-type, rear-end raised towing method; or
• the wheel-lift towing method with a tow dolly lo­
cated under the front wheels. A vehicle with flat-bed hauling equipment can also
be used to transport a disabled vehicle.

INSPECTION/LUBRICATION SCHEDULE

2WD
VEHICLES
It is recommended that 2WD front wheel bearings
be inspected for proper lubrication whenever the
brake rotors are removed or at least: • At each 39 000 km (24,000 miles) interval for ve­
hicles subject to the LIGHT DUTY CYCLE Mainte­ nance Schedule • At each 36 000 km (22,500 miles) interval for ve­
hicles subject to the HEAVY DUTY CYCLE Mainte­ nance Schedule The bearings should be cleaned and re-packed
with a high temperature, multi-purpose EP lu­
bricant.
4WD
VEHICLES

It is recommended that 4WD front wheel bearings
be inspected for proper lubrication whenever the
brake rotors are removed or at least:
• At each 24 000 km (15,000 miles) interval for ve­
hicles subject to the LIGHT DUTY CYCLE Mainte­ nance Schedule
• At each 19 000 km (12,000 miles) interval for ve­
hicles subject to the HEAVY DUTY CYCLE Mainte­ nance Schedule
For vehicles used for extensive off-road, 4WD
operation, the front wheel bearings should be in­ spected every 1 600 km (1,000 miles).
The bearings should be cleaned and re-packed
with a high temperature, multi-purpose EP lu­
bricant whenever the disc brake rotors are re­ surfaced.
INSPECTION If the lubricant:
• Is not sufficient
• Contaminated with foreign particles
• Appears dry or has been contaminated with water
to produce a milky appearance, the bearings should
be cleaned and re-packed with lubricant.

CAUTION:
Do not add
lubricant
to the
wheel
bear­
ings.
Re-pack completely. Mixing
of
different
types
of lubricants
in
wheel
bearings should
be
avoided.
This could possibly result
in
excessive thinning
and
leakage
of the
lubricant.

LUBRICATION (1) Discard the original seal.
(2) Clean the original lubricant from the bearings
and from the hub cavity (Figs. 2 and 3).
(3) Inspect the bearing rollers for indications of
pitting. Light bearing roller discoloration is consid­ ered normal. A wheel bearing must be replaced if any serious damage exists.
(4) Re-pack the bearings with a high temperature,
multi-purpose NLGI GC-LB lubricant. The use of a
bearing packer is recommended. A small amount of fresh lubricant also should be added to the hub cav­ ity.
BEARING INSTALLA TION/ADJUSTMENT (1) Install the hub/rotor (with inner bearing and
seal) on steering knuckle spindle.
(2) Install the outer bearing, the thrust washer
and the nut.
(3) Tighten wheel bearing nut to 27-34 N^m (240-
300 in. lbs.) torque while rotating hub/rotor. This
will seat the bearings.
(4) Loosen the nut 1/4 of-a-turn (90°), then tighten
it finger-tight.

FRONT
WHEEL
ALIGNMENT

GENERAL
INFORMATION
Front wheel alignment involves
the
correct posi­
tioning
of the
tire contact patch
in
relation
to the

pavement.
The
positioning
is
accomplished through
the suspension
and
steering linkage adjustments.
An
alignment
is
essential
for
efficient steering
and
direc­
tional stability.
The
most important factors
of
front
end alignment
are
camber, caster
and toe
position. Routine inspection
of
the front
suspension
and
steering components
is a
good
preventative

maintenance practice.
Inspection
also
helps
to
ensure
safe operation
of the
vehicle.

• CAMBER
is the
number
of
degrees
the top of the

wheel
is
tilted either inward
or
outward.
An
excessive
negative camber angle will cause tread wear
at the in­
side
of
the tire.
An
excessive positive camber angle will
cause tread wear
at the
outside
of
the tire (Fig.
1),
• CASTER
is the
number
of
degrees
of
forward
or

rearward tilt
of the
steering knuckles. Forward tilt
provides
a
negative caster angle. Rearward tilt pro­ vides
a
positive caster angle
(Fig. 1).

• WHEEL
TOE
POSITION
is the
difference between
the leading
and
trailing inside edges
of the
front
tires (Fig.
1).
Incorrect wheel
toe
position
is the
most common cause
of
unstable steering
and
steering wheel off-center.
The
wheel
toe
position
is the
final
front wheel alignment adjustment. • STEERING AXIS INCLINATION ANGLE
is
mea­
sured
in
degrees
and is the
angle that
the
steering
knuckles
are
tilted (Fig. 1).
The
inclination angle
has

a fixed relationship with
the
camber angle. This will
not change except when
a
spindle
or
ball stud
is

damaged
or
bent.
The
angle
is not
adjustable
and the

damaged component(s) must
be
replaced
to
correct
mis-alignment.

CAUTION:
Do not
attempt to modify
any
suspension

or steering
component
by
heating
and
bending.

PRE-ALIGNMENT INSPECTION
Before starting
a
front wheel alignment,
the
follow­
ing inspection
and
necessary corrections must
be
completed.
(1)
Tires with
the
same recommended
air
pressure,

size,
and
tread wear. Refer
to
Group
22,
Wheels
and

Tires
for
diagnosis information. (2) Front wheel bearings
for
wear
or
adjustment.
(3) Ball studs
and
linkage pivot points, steering
gear
for
looseness, roughness, binding
or a
sticking
condition. Refer
to
Group
19,
Steering
for
additional information.

2 - 5 (4) Front wheels for excessive radial, lateral
runout and unbalance. Refer to Group 22, Wheels and Tires for diagnosis information.
(5) Suspension components for wear and noise. Check
components for correct torque. Refer to Groups 2 and 3, Suspension and Axle for additional information.

WHEEL
ALIGNMENT
MEASUREMENTS/ADJUSTMENTS
The front wheel alignment positions must be set to
the specified limits. This will prevent abnormal tire
tread wear. The equipment manufacturer&#39;s recommenda­
tions for use of their
equipment
should always
be followed. All
damaged
front suspension sys­
tem components
should
be replaced. Do not at­ tempt to straighten any
bent
component.

CAMBER AND CASTER-2WD VEHICLES Camber and caster angle adjustments involve repo­
sitioning the upper suspension arm cam adjustment
bolts (Fig. 2). Alignment adjustments are accom­
plished by loosening the nuts and changing the posi­
tion of the cam bolt.
(1) Remove all foreign material from the adjust­
ment bolt threads.
(2) Record the camber and caster measurements
before loosening the adjustment bolt nuts.
(3) The camber angle should be adjusted as near as
possible to the preferred angle. The caster should be
the same at both sides of the vehicle. Refer to the Specifications chart.
CAMBER AND CASTER—4WD VEHICLES For 4WD vehicles, the correct wheel camber (verti­
cal tilt) angle is factory preset at zero degree (0°).
Camber cannot be altered by adjustment.
CAUTION: Do not attempt to
adjust
the
camber
an­
gle by
heating
or bending the axle or any
suspen­

sion
component. If camber angle is
incorrect,
the
component(s)
causing
an
incorrect
angle must be replaced.
(1) It is important that the camber (vertical tilt)
angle be the same for both front wheels.
(2) The camber angle should be measured with ac­
curate wheel alignment equipment. The acceptable
range is -1° to +1°. Refer to the Specifications chart.
Road test the vehicle and observe the steering
wheel return-to-center position. Before road testing,
check
and
correct
the tire
inflation pressures. Inflate
both
of the front tires
with exactly the
same
pressure.
During the road test, make vehicle turns to both
the left and right. If the steering wheel returns to­
ward the center position unassisted, the caster angle is correct. However, if the steering wheel does not re­ turn toward the center position unassisted, an incor­
rect caster angle is probable.
(1) The caster angle is factory preset at positive
two degrees
(
+
2°).
The acceptable range is +1/2° to +
3
1/2°.
(2) The caster angle should be measured with ac­
curate wheel alignment equipment.
(3) Caster angle can be adjusted by installing ta­
pered shims between the front axle pads and the spring brackets. The caster angle should be adjusted
as near as possible to the preferred angle.
(4) Record the caster measurement before remov­
ing the original shims from the spring pads.
(5) The caster should be the same at both sides of
the vehicle. Refer to the Specifications chart.

WHEEL TOE POSITION The wheel toe position adjustment should be the fi­
nal front wheel alignment adjustment. In all in­ stances, follow the equipment manufacturer&#39;s
recommended procedure.
(1) Secure the steering wheel with the front wheels
in the straight-ahead position. For vehicles equipped
with power steering, start the engine before straight­ ening the wheels.
With power steering, the engine should be op­
erating during the wheel toe position adjust­
ment.
(2) Loosen the tie rod adjustment sleeve clamp
bolts (Fig. 3).
(3) Adjust the wheel toe position by rotating the
tie rod adjustment sleeve (Fig. 3). Rotate each tie-rod end in the direction of
sleeve rotation during the adjustment (Fig. 3).
This will ensure that both tie-rod ends are at the center of their travel.
(4) If applicable, turn the ignition switch off.
