VEHICLE EMISSION CONTROL
INFORMATION (VECI)
DESCRIPTION
All models have a Vehicle Emission Control Infor-
mation (VECI) Label. DaimlerChrysler permanently
attaches the label in the engine compartment (Fig.
2). The label cannot be removed without defacing
label information and destroying label.
The label contains the vehicle's emission specifica-
tions and vacuum hose routings. All hoses must be
connected and routed according to the label.
The label also contains an engine vacuum sche-
matic. There are unique labels for vehicles built for
sale in the state of California and the country of
Canada. Canadian labels are written in both the
English and French languages.
The VECI label contains the following:
²Engine family and displacement
²Evaporative family
²Emission control system schematic
²Certification application
²Engine timing specifications (if adjustable)²Idle speeds (if adjustable)
²Spark plug and gap

WHEEL ALIGNMENT
DESCRIPTION
NOTE: Suspension components with rubber/ure-
thane bushings should be tightened with the vehi-
cle at normal ride height. It is important to have the
springs supporting the weight of the vehicle when
the fasteners are torqued. If springs are not at their
normal ride position, vehicle ride comfort could be
affected and premature bushing wear may occur.
Wheel alignment involves the correct positioning of
the wheels in relation to the vehicle. The positioning
is accomplished through suspension and steering
linkage adjustments. An alignment is considered
essential for efficient steering, good directional stabil-
ity and to minimize tire wear. The most important
measurements of an alignment are caster, camber
and toe (Fig. 1).
CAUTION: Never attempt to modify suspension or
steering components by heating or bending.

STANDARD PROCEDURE
STANDARD PROCEDURE - HEIGHT
MEASUREMENT - 4WD (LD)
The vehicle suspension height MUST be measured
and adjusted before performing wheel alignment pro-
cedure. Also when front suspension components have
been replaced. This measure must be performed with
the vehicle supporting it's own weight and taken on
both sides of the vehicle.
(1) Inspect tires and set to correct pressure.
(2) Jounce the front of the vehicle.
(3) Measure and record the height from the ground
at the centerline of the rear lower control arm bolt
front tip (Fig. 2).
(4) Measure and record the height from the ground
at the front spindle centerline (Static Load Radius)
(Fig. 2).
(5) Subtract the first measurement from the sec-
ond measurement. The difference between the two
measurement should be 58 mm (2.3 inches) 3mm
(0.12 inches).
(6) If value is greater than 61 mm (2.4 inches),
tighten the torsion bar bolt until the specification is
achieved (Refer to 2 - SUSPENSION/WHEEL
ALIGNMENT - STANDARD PROCEDURE).
(7) If value is less than 55 mm (2.1 inches), loosen
the torsion bar bolt until the specification is achieve-
d,(Refer to 2 - SUSPENSION/WHEEL ALIGNMENT
- STANDARD PROCEDURE).
(8) Repeat the previous steps until the ride height
is within specifications.
STANDARD PROCEDURE - HEIGHT
ADJUSTMENT - 4WD (LD)
The vehicle suspension height MUST be measured
and adjusted before performing wheel alignment pro-
cedure (Refer to 2 - SUSPENSION/WHEEL ALIGN-
MENT - STANDARD PROCEDURE). Also when
front suspension components have been replaced.
This measurement must be performed with the vehi-
cle supporting it's own weight and taken on both
sides of the vehicle.

To adjust the vehicle height turn the torsion bar
adjustment bolt CLOCKWISE to raise the vehicle
and COUNTER CLOCKWISE to lower the vehicle.
CAUTION: ALWAYS raise the vehicle to the correct
suspension height, NEVER lower the vehicle to
obtain the correct suspension height. If the vehicle
suspension height is too high, lower the vehicle
below the height specification. Then raise the vehi-
cle to the correct suspension height specification.
This will insure the vehicle maintains the proper
suspension height.
NOTE: If a height adjustment has been made, per-
form height measurement again on both sides of
the vehicle.
STANDARD PROCEDURE - CAMBER AND
CASTER ADJUSTMENT
NOTE: 4X4 (LD) SUSPENSION HEIGHT MEASURE-
MENT MUST BE PERFORMED BEFORE AN ALIGN-
MENT.
NOTE: When the upper control arm pivot bolts are
loosened the upper control arm will normally go
inwards toward the frame automatically with the
weight of the vehicle.
Camber and caster angle adjustments involve
changing the position of the upper control arm incon-
junction with the slotted holes in the frame brackets,
Install special tool 8876 between the top of the upper
control arm bracket and the upper control arm (on
1500 series 4X2 & 4X4). Install special tool 8876
between the bottom of the upper control arm bracket
pressing the tool against the frame and the upper
control arm (on 2500/3500 series 4X2) in order to
move the upper control arm outwards for proper
adjustment with the vehicle at normal ride height
(Fig. 3).
STANDARD PROCEDURE - TOE ADJUSTMENT
4X4 SUSPENSION HEIGHT MESUREMENT
MUST BE PERFORMED BEFORE AN ALIGN-
MENT.
The wheel toe position adjustment is the final
adjustment.
(1) Start the engine and turn wheels both ways
before straightening the wheels. Secure the steering
wheel with the front wheels in the straight-ahead
position.
(2) Loosen the tie rod jam 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
inner tie rod as necessary (Fig. 4).
(4) Tighten the tie rod jam nut to 75 N´m (55 ft.
lbs.).
(5) Verify the specifications
(6) Turn off engine.
STANDARD PROCEDURE - CAMBER, CASTER
AND TOE ADJUSTMENT
NOTE: 4X4 (LD) SUSPENSION HEIGHT MEASURE-
MENT MUST BE PERFORMED BEFORE AN ALIGN-
MENT.
Camber and caster angle adjustments involve
changing the position of the upper control arm with
the slots in the frame brackets using special tool
8876 to move the upper control arm outwards for
proper adjustment. (Fig. 3)
NOTE: When the upper control arm pivot bolts are
loosened the upper control arm will normally go
inwards toward the frame automatically with the
weight of the vehicle.
CASTER
Moving the front or rear position of the upper con-
trol arm in or out, will change the caster angle and
camber angle significantly. To maintain the camber

FRONT SUSPENSION
DESCRIPTION
DESCRIPTION
The front suspension is designed to allow each
wheel to adapt to different road surfaces indepen-
dently. The wheels are mounted to hub/bearings
units bolted to the steering knuckle. The double-row
hub bearings are sealed and lubricated for life. The
steering knuckles turn (pivot) on ball joints.
The front suspension is comprised of (Fig. 1) (Fig.
2):
²Shock absorbers
²Torsion bar - 4X4 (LD only)
²Coil Spring - 4X2
²Control arms
²Steering knuckles
²Stabilizer bar
²Stabilizer link
²Tie Rod Ends
²Hub/Bearing
²Rack & Pinion
²Ball Joints
NOTE: Components attached with a nut must be
torqued to specification.
NOTE: Suspension components with rubber/ure-
thane bushings should be tightened with the vehi-
cle at normal ride height. It is important to have the
springs supporting the weight of the vehicle when
the fasteners are torqued. If springs are not at their
normal ride position, vehicle ride comfort could be
affected and premature bushing wear may occur.
