[x] Cancel search: oil levelPage 986 of 1378
(
1) - SAE 10W-30 SH/CD is preferred.
(
2) - Add 4 ozs. (118 ml) of Limited-Slip differential lubricant
additive when changing fluid.
(
3) - For vehicles operating under heavy-duty towing conditions,
use SAE 75W-140 Synthetic lube.
NOTE: Before using SAE 75W-140 Synthetic the old fluid must
be DRAINED and FLUSHED with clean mineral based axle
lubricant. Then refill with new synthetic lube.
(
4) - Use low pressure grease gun to prevent seal damage.
(
5) - Fill until lubricant squeezes out from the base of seals.
(
6) - Fill ball joint until seal starts to swell.

1) Voltage is applied to ignition switch through fuse "B" at
all times. Voltage is also applied at all times to the contact on
starter solenoid, terminal "B".
2) With ignition switch in "START" position, battery voltage
is applied from fusible link "B", to ignition switch, and to the coil
of the starter relay to ground.
3) The coil of the starter relay engages closing relay
contacts. With start relay contacts closed, battery voltage is applied
to starter solenoid. Both solenoid windings are energized.
4) The pull-in and hold-in windings work together to
magnetically pull starter gear into ring gear. At the same time the
plunger also closes solenoid switch contacts in the starter solenoid.
Full battery voltage is now applied directly to the starter motor and
it cranks the engine.
NOTE: Use the amperage draw reading after the starter motor has
obtained its maximum RPM.
TROUBLE SHOOTING
* Check the battery for a broken or cracked casing.
* Check that all connections to battery and starter are clean
and tight.
* Check electrolyte level of battery. Levels that are too high
or too low may cause poor starter motor performance.
* Check battery by measuring specific gravity of electrolyte in
each cell with a hydrometer.
NOTE: No further testing or troubleshooting procedures available
from manufacturer.

Will Not Shift Or Difficult To Shift Into Gear
Vehicle speed too high; slow vehicle to 2-3 MPH to shift.
Vehicle operated too long on dry paved surface; stop vehicle and place
in Reverse or Neutral to relieve driveline torque. Ensure transfer
case external linkage is not binding. Ensure correct fluid is used.
Internal parts may be worn or damaged.
Noisy In All Gears
Check fluid level. Ensure correct fluid is used. If fluid is
okay, locate possible internal mechanical problem.
Jumps Out Of Gear Or Noisy In 4WD
Transfer case not completely in gear; check shift linkage.
Range fork damaged. Shift fork pads are worn or shift fork binding.
Low range gear worn.
Fluid Leaking From Vent Or Seals
Transfer case overfilled. Vent plugged. Output shaft seals
are damaged or not installed properly.
ON-VEHICLE SERVICE
FRONT OIL SEAL
Removal & Installation
1) Mark front drive shaft and flange for installation
alignment reference. Remove front drive shaft. Remove flange. Discard
washer and nut. Using a screwdriver, carefully remove oil seal. Ensure
seal contact surface is clean.
2) Apply ATF to seal lip and flange seal surface. Install NEW
oil seal. Install flange and NEW washer and nut. Tighten nut to
specifications. See TORQUE SPECIFICATIONS . Install front drive shaft
using alignment marks. Check transfer case fluid.
EXTENSION HOUSING OIL SEAL & BUSHING
Removal & Installation
1) Mark rear drive shaft and flange for installation
alignment reference. Remove rear drive shaft. Tap extension housing in
a clockwise direction and remove extension housing. DO NOT pry on
extension housing. Using a screwdriver, remove oil seal from extension
housing.
2) Using bushing driver, replace bushing in extension
housing. Install NEW extension housing oil seal. Apply silicone
sealant to extension housing mating surface. Install extension
housing. To complete installation, reverse removal procedure.
REMOVAL & INSTALLATION
TRANSFER CASE
Removal
1) Shift transfer case into 4H and disconnect battery
negative cable. Raise vehicle, remove skid plate and drain fluid.
2) Mark front and rear output shaft yokes to drive shafts for
reassembly reference. Support transfer case and remove rear
crossmember. Remove drive shafts.
3) Disconnect vehicle speed sensor electrical connector and
vacuum (hoses) harness at transfer case. Remove shift lever or linkage\
rod from case. Remove transfer case attaching bolts. Remove transfer
case from vehicle.

Jeep - New Venture 242
Cherokee, Comanche, Wagoneer, Grand Wagoneer
IDENTIFICATION
Transfer case can be identified by an I.D. tag, located on
rear case. I.D. tag provides model number, serial number and low range
ratio. Date of manufacture is the serial number (I.D. number). This
information is necessary when ordering parts.
DESCRIPTION
Model 242 transfer case is a chain-driven, 2-piece aluminum
case, with full time operation. Torque input in 4WD high and low range
is undifferentiated.
ADJUSTMENTS
GEARSHIFT LINKAGE
Remove shift boot and shift to 4L position. Loosen trunnion
nut. Adjust trunnion and shift rod until rod fits freely. Tighten
trunnion nut and remove shim.
TROUBLE SHOOTING
SYMPTOM DIAGNOSIS
Will Not Shift Or Difficult To Shift Into Gear
Check fluid level. Check linkage adjustment. Ensure transfer
case external linkage is not binding. Internal parts may be worn or
damaged.
Noisy In All Gears
Check fluid level. Ensure correct fluid is used. If fluid is
okay, locate noise and check for possible internal mechanical problem.
Jumps Out Of Gear Or Noisy In 4WD
Transfer case not completely in gear; check shift linkage.
Range fork damaged. Inserts are worn. Shift fork binding on shift
rail. Low range gear worn or damaged.
Fluid Leaking From Vent Or Seals
Transfer case overfilled. Vent plugged. Output shaft seals
are damaged or not installed properly.
Transfer Case Will Not Shift Through High Lock Range
Incomplete shift due to driveline torque load; momentarily
release accelerator pedal to complete shift. Check tire pressure and
tire wear. Vehicle overloaded; remove load and check shifting.
