ADJUSTMENT
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective com-
ponents that could interfere with proper headlamp
alignment.
(3) Verify proper tire inflation.
(4) Clean headlamp lenses.
(5) Verify that luggage area is loaded as the vehi-
cle is routinely used.
(6) Fuel tank should be FULL. Add 2.94 kg (6.5
lbs.) of weight over the fuel tank for each estimated
gallon of missing fuel.
ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 7.62 meters (25 ft.) away from front
of headlamp lens (Fig. 13).
(2) If necessary, tape a line on the floor 7.62
meters (25 ft.) away from and parallel to the wall.
(3) Rock vehicle side-to-side three times and allow
suspension to stabilize.
(4) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(5) Measure the distance from the center of head-
lamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for
up/down adjustment reference.

HEADLAMP ADJUSTMENT
The low beam headlamp will project on the screen
upper edge of the beam (cut-off) at the horizontal
lamp centerline   20 mm (0.75 in.). The high beam
pattern should be correct when the low beams are
aligned properly (Fig. 9). To adjust headlamp align-
ment, rotate adjustment screws to achieve the speci-
fied low beam cut-off location.

LOWER DRIVE UNIT TRACK &
RACK
DESCRIPTION
Vehicles equipped with a power sliding side door uti-
lize a lower drive unit track or door track and rack
assembly. This track provides a mating rack gear (Fig.
13) for the lower drive unit to engage. The track also
accepts the lower hinge rollers, which helps support the
weight of the side door as well as providing a smooth
surface for the hinge rollers to move upon.
The lower door track is a replaceable component.
Consult your Mopar parts catalog for specific part
numbers.
OPERATION
With the start of a power door open cycle, the door
motor drives the flex drive assembly. The flex drive
assembly drives the lower drive unit. A powdered
metal drive gear which is part of the lower drive
unit, meshes with the door track rack teeth and
moves the door into the full open position. The same
operation repeats itself, during a power close cycle
only the system rotates in the opposite direction.
REMOVAL
(1)Disconnect and isolate the negative battery cable.
(2) Remove the side door sill plate from the lower
of the door opening. Refer to the Body section for the
procedure.
(3) Remove the hold-open striker. Refer to Body for
the procedure.
(4) Position a floor jack, with a block of wood
under the leading edge of the side door to support it
(Fig. 15).
(5) Remove the lower drive unit. Refer to the pro-
cedure in this section.
(6) Position the wire harness assembly out of door
opening (Fig. 13), this will allow the door track to be
removed easily.
(7) Pull back sealing patches (Fig. 13) and remove
the lower track retaining nuts (Fig. 14).

CRANKSHAFT
DESCRIPTION
The crankshaft is made of nodular cast iron and
includes five main bearing journals and four connect-
ing rod journals (Fig. 47). The number three journal
is the location for the thrust bearing. The mains and
connecting rod journals have undercut fillet radiuses
that are rolled for added strength. To optimize bear-
ing loading, eight counterweights are used.
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder to the flywheel or flex-
plate.
STANDARD PROCEDURE - CRANKSHAFT END
PLAY
(1) Using Dial Indicator C-3339 and Mounting
Post L-4438, attach to front of engine, locating probe
perpendicular on nose of crankshaft (Fig. 48).
(2) Move crankshaft all the way to the rear of its
travel.
(3) Zero the dial indicator.
(4) Move crankshaft all the way to the front and
read the dial indicator. Refer to Engine Specifica-
tions.
REMOVAL
NOTE: Crankshaft can not be removed when engine
is in vehicle.
(1) Remove engine assembly from vehicle. (Refer to
9 - ENGINE - REMOVAL)
(2) Separate engine from transaxle.
(3) Remove flex plate and crankshaft rear oil seal.
(4) Mount engine on a repair stand.
(5) Drain engine oil and remove oil filter.
(6) Remove the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - REMOVAL)
(7) Remove the timing belt covers. (Refer to 9 -

(4) Apply 1.5 to 2.0 mm (0.059 to 0.078 in.) bead of
MopartBed Plate Sealant to cylinder block as shown
in (Fig. 52).
(5) Install lower main bearings into main bearing
cap/bedplate. Make certain the bearing tabs are
seated into the bedplate slots. Install the main bear-
ing/bedplate into engine block.
(6) Before installing the bolts the threads should
be oiled with clean engine oil, wipe off any excess oil.
(7) Install main bearing bedplate to engine block
bolts 11, 17, and 20 finger tight. Tighten these bolts
down together until the bedplate contacts the cylin-
der block.
(8) To ensure correct thrust bearing alignment,
perform the following steps:
²Step 1: Rotate crankshaft until number 4 piston
is at TDC.
²Step 2: Move crankshaft rearward to limits of
travel.
²Step 3: Then, move crankshaft forward to limits
of travel.
²Step 4: Wedge an appropriate tool between the
rear of the cylinder block(NOT BED PLATE)andthe rear crankshaft counterweight. This will hold the
crankshaft in it's furthest forward position.
²Step 5: Install and tighten bolts (1±10) in
sequence shown in (Fig. 53) to 41 N´m (30 ft. lbs.).
²Step 6: Remove wedge tool used to hold crank-
shaft.
(9) Tighten bolts (1±10) again to 41 N´m (30 ft.
lbs.) +1/4 turn in sequence shown in (Fig. 53).
(10) Install main bearing bedplate to engine block
bolts (11±20), and torque each bolt to 28 N´m (20 ft.
lbs.) in sequence shown in (Fig. 53).
(11) After the main bearing bedplate is installed,
check the crankshaft turning torque. The turning
torque should not exceed 5.6 N´m (50 in. lbs.).
(12) Install balance shafts and housing assembly.
