GENERAL INFORMATION
INTRODUCTION
Service and maintenance procedures for compo-
nents and systems listed in Schedule ± A or B can be
found by using the Group Tab Locator index at the
front of this manual. If it is not clear which group
contains the information needed, refer to the index at
the back of this manual.
There are two maintenance schedules that show
proper service based on the conditions that the vehi-
cle is subjected to. Use the schedule that best
describes these conditions.
Schedule ±A, lists maintenance recommended for
vehicles used for general transportation.
Schedule ±B, lists maintenance recommended for
vehicles used under the following conditions:
²Frequent short trip driving less than 5 miles (8
km)
²Frequent driving in dusty conditions
²Frequent trailer towing
²Extensive idling
²More than 50% of your driving is at sustained
high speeds during hot weather, above 90ÉF (32ÉC)
Where time and mileage are listed, follow the
interval that occurs first.
EMISSION CONTROL SYSTEM MAINTENANCE
The scheduled emission maintenance listed inbold
typeon the Maintenance Schedules, must be done at
the mileage specified to assure the continued proper
functioning of the emission control system. These,
and all other maintenance services included in this
manual, should be done to provide the best vehicle

GENERAL INFORMATION
FRONT DRIVESHAFTS
Vehicles equipped with either an automatic or
manual transmission use the unequal±length drive-
shaft system.
Vehicles equipped with automatic transaxles use a
solid short interconnecting shaft on the left side. The
right side of the vehicle uses a longer solid intercon-
necting shaft (Fig. 1).
Vehicles equipped with manual transaxles use a
larger diameter (32 mm) short interconnecting shaft
on the left side. The right side uses a longer inter-
connecting damper (Fig. 1).Driveshafts used on both the right and left sides of
the vehicle use a tuned rubber damper weight. The
damper weight applications vary by which side of the
vehicle the driveshaft is located on and the transmis-
sion application of the vehicle. When replacing a
driveshaft, be sure the replacement driveshaft has
the same damper weight as the original.
Both driveshaft assemblies use the same type of
inner and outer joints. The inner joint of both drive-
shaft assemblies is a tripod joint, and the outer joint
of both driveshaft assemblies is a Rzeppa joint. Both
tripod joints and Rzeppa joints are true constant
velocity (C/V) joint assemblies. The inner tripod joint
allows for the changes in driveshaft length through

wheel. Then, using the screwdriver rotate the star-
wheeldownwardjust until the rear tire and wheel
can be rotated with no park brake shoe drag. From
the point where there is no more park brake drag
rotate the starwheeldownwarda maximum of two
additional clicks. The park brake shoe to drum clear-
ance is know properly adjusted.
(6) Install the rubber plug in the adjusting hole on
the brake shoe backing plate on both sides of the
vehicle.
(7) Lower vehicle far enough to allow access the
park brake lever. The rear tires must not be on the
ground.
(8) Fully apply and release the park brakes two
times after adjusting the park brake shoes. Then
rotate both rear wheels to ensure that the park
brake shoes do not drag on the brake drum following
the application and release of the park brakes.
SPECIFICATIONS
BRAKE FLUID
The brake fluid used in this vehicle must conform
to DOT 3 specifications and SAE J1703 standards.
No other type of brake fluid is recommended or
approved for usage in the vehicle brake system. Use
only Mopar brake fluid or an equivalent from a
tightly sealed container.
CAUTION: Never use reclaimed brake fluid or fluid
from an container which has been left open. Anopen container will absorb moisture from the air
and contaminate the fluid.
CAUTION: Never use any type of a petroleum-
based fluid in the brake hydraulic system. Use of
such type fluids will result in seal damage of the
vehicle brake hydraulic system causing a failure of
the vehicle brake system. Petroleum based fluids
would be items such as engine oil, transmission
fluid, power steering fluid ect.

CLUTCH PEDAL POSITION
SWITCH±MECHANICAL TEST
With the park brake set and the vehicleIN NEU-
TRAL,turn the key to the start position. The vehicle
should not crank. If the vehicle cranks, the switch is
defective (shorted out) and must be replaced. If the
vehicle does not crank, proceed to the next step.
WARNING: BEFORE PERFORMING THIS STEP, BE
SURE THAT THE AREA IN FRONT OF THE VEHICLE
IS CLEAR OF OBSTRUCTIONS AND PEOPLE. VEHI-
CLE MAY MOVE WHEN PERFORMING THIS TEST.
With the park brake set and the vehicleIN GEAR,
turn the key to the start position and hold it there.
Slowly depress the clutch pedal and feel for any
vehicle motion when the starter is energized. If there
is no motion, the switch is working properly.
If motion is felt, check to see if the switch is mak-
ing contact when the pedal is between 25 mm (1.0
in.) and 6 mm (0.25 in.) from the floor. If this condi-
tion is met, then the problem is either the clutch orthe self-adjusting cable (See ªClutch Will Not Disen-
gage Properlyº). If this condition is not met, then the
switch mounting tab on the brake bracket is bent,
and the brake bracket must be replaced.
If vehicle will not crank, even with clutch pedal
pressed to the floor, refer to ªService Diagnosis-
Clutch Pedal Position Switchº chart in this section.
CLUTCH DIAGNOSIS
Problem diagnosis will generally require a road
test to determine the type of fault. Component
inspection will then determine the problem after road
testing.
Drive the vehicle at normal speeds during road
test. Shift the transaxle through all gear ranges and
observe clutch action. If chatter, grab, slip, or
improper release is experienced, remove and inspect
the clutch components. If the problem is noise or
hard shifting, further diagnosis may be needed. The
transaxle or other driveline components may actually
be at fault.

DIAGNOSIS AND TESTING (Continued)

DRIVE PLATE MISALIGNMENT
Common causes of misalignment are:
²Heat warping
²Mounting drive plate on a dirty crankshaft
flange
²Incorrect bolt tightening
²Improper seating on the crankshaft shoulder
²Loose crankshaft bolts
Clean the crankshaft flange before mounting the
drive plate. Dirt and grease on the flange surface
may misalign the flywheel, causing excessive runout.
Use new bolts when mounting drive plate to crank-
shaft. Tighten drive plate bolts to specified torque
only. Over-tightening can distort the drive plate hub
causing excessive runout.
CLUTCH COVER AND DISC RUNOUT
Check condition of the clutch cover before installa-
tion. A warped cover or diaphragm spring will cause
grab and/or incomplete release or engagement. Use
care when handling the clutch assembly. Impact can
distort the cover, diaphragm spring, and release fin-
gers.
CLUTCH CHATTER COMPLAINTS
For all clutch chatter complaints, do the following:
(1) Check for loose, misaligned, or broken engine
and transmission mounts. If present, they should be
corrected at this time. Test vehicle for chatter. If
chatter is gone, there is no need to go any further. If
chatter persists:
(2) Check to see if clutch cable routing is correct
and operates smoothly.
(3) Check for loose connections in drive train. Cor-
rect any problems and determine if clutch chatter
complaints have been satisfied. If not:
(4) Remove transaxle. See Group 21, Manual Tran-
saxle for procedure.
(5) Check to see if the release bearing is sticky or
binding. Replace bearing, if needed.
(6) Check linkage for excessive wear on the pivot
stud and fork fingers. Replace all worn parts.
(7) Check clutch assembly for contamination (dirt,
oil). Replace clutch assembly, if required.
(8) Check to see if the clutch disc hub splines are
damaged. Replace with new clutch assembly, if nec-
essary.
(9) Check input shaft splines for damage. Replace,
if necessary.
(10) Check for uneven wear on clutch fingers.
(11) Check for broken clutch cover diaphragm
spring fingers. Replace with new clutch assembly, if
necessary.
CLASH±INTO±REVERSE COMPLAINTS
Certain NV T350 (A-578) manual transaxles are
equipped with a reverse brake. It prevents clash
when shifting into reverse, but only if the vehicle is
not moving. See Group 21, Transaxle for further
diagnosis.
(1) Depress clutch pedal to floor and hold. After
three seconds, shift to reverse. If clash is present,
clutch has excessive spin time, and the reverse brake
may not be functioning.
(2) Remove transaxle. See Group 21, Manual Tran-
saxle for procedure.
(3) Check the input shaft spline, clutch disc
splines, and release bearing for dry rust. If present,
clean rust off and apply a light coat of bearing grease
to the input shaft splines. Apply grease on the input
shaft splines only where the clutch disc slides. Verify
that the clutch disc slides freely along the input shaft
spline.
(4) Check to see if the clutch disc hub splines are
damaged, and replace with new clutch assembly if
required.
(5) Check the input shaft for damaged splines.
Replace as necessary.
(6) Check for broken clutch cover diaphragm
spring fingers.
(7) Install clutch assembly and transaxle.
REMOVAL AND INSTALLATION
