2.VISUAL INSPECTION
NOTE: This code can set due to tire circumference differences and from the front or rear wheels being on
a slippery surface while the opposite tires are not.
This code may also set on a hard acceleration on loose gravel or during otheroff road driving conditions.
Check tire pressure of all the tires.

of the power steering pump along with the maximum
relief pressure. Perform test any time a power steering
system problem is present. This test will determine if
the power steering pump or power steering gear is not
functioning properly. The following pressure and flow
test is performed using Power Steering Analyzer Tool
kit 6815 and Adapter Kit 6893.

TIE ROD END
DIAGNOSIS AND TESTING
OUTERTIERODEND
NOTE: If the outer tie rod end is equipped with a lubrication fitting, grease the joint then road test the vehi-
cle before performing test.
1. Raise the front of the vehicle. Place safety floor stands under both lower control arms as far outboard as pos-
sible. Lower the vehicle to allow the stands to support some or all of the vehicle weight.
2. Remove the front tires.
3. Mount a dial indicator solidly to the vehicle steering knuckle and then zero the dial indicator.
4. Position indicator plunger on the topside of the outer tie rod end.
NOTE: The dial indicator plunger must be perpendicular to the machined surface of the outer tie rod end.
5. Position a pry bar in order to pry downwards on the outer tie rod end.
6. If the travel exceeds 0.5 mm (0.020 in.), replace the outer tie rod end (Refer to 19 - STEERING/LINKAGE/TIE
ROD END - REMOVAL).
7. If the outer tie rod end is within specs reinstall the front tires (Refer to 22 - TIRES/WHEELS/WHEELS - STAN-
DARD PROCEDURE).
REMOVAL - OUTER TIE ROD END
NOTE: Do not twist the boot anytime during
removal or installation.
1. Loosen the jam nut (3).
2. Remove the outer tie rod end nut from the ball
stud.
3. Separate the tie rod ball stud (1) from the knuckle
with Remover 9360 (2).
4. Unthread the outer tie rod end (1) from the inner tie
rod.

A straight line shift pattern is used with a NEUTRAL detent. Lever range positions are imprinted in the shift knob.
SHIFTING
The transfer case can be shifted between the 2H and 4H operating ranges while the vehicle is in motion. The vehi-
cle must have the transmission placed in NEUTRAL, or the clutch depressed in the case of a manual transmission,
and be moving less than 2-3 MPH when shifting into and out of the 4L operatingrange.
DIAGNOSIS AND TESTING - TRANSFER CASE - NV241 GENII
Before beginning repair on a suspected transfer case malfunction, check all other driveline components beforehand.
The actual cause of a problem may be related to such items as: front hubs, axles, propeller shafts, wheels and tires,
transmission, or clutch instead. If all other driveline components are ingood condition and operating properly, refer
to the Diagnosis Chart for further information.
DIAGNOSIS CHART
Condition Possible Cause Correction
Transfer Case difficult to shift or will
not shift into desired range.1) Vehicle speed too great to permit
shifting.1) Stop vehicle and shift into
desired range. Or, reduce speed to
below 3-4 km/h (2-3 mph) before
attempting the shift.
2) If vehicle was operated for an
extended period in 4H on a dry
paved surface, the driveline torque
load may be causing a bind.2) Stop vehicle and shift the
transmission into neutral. Shift the
transfer case to 2H and operate
vehicle in 2H on dry paved
surfaces.
3) Transfer case external shift
linkage binding.3) Lubricate, repair, or replace
linkage bushings, or tighten loose
components as necessary.
4) Insufficient or incorrect lubricant. 4) Drain and refill to edge of fillhole
with Mopar
ATF +4, Automatic
Transmission fluid.
5) Internal components binding,
worn, or damaged.5) Disassemble the transfer case
and replace worn or damaged
components as necessary.
Transfer Case noisy in all operating
ranges.1) Insufficient or incorrect lubricant. 1) Drain and refill to edge of fillhole
with Mopar
ATF +4, Automatic
Transmission fluid.
Noisy in, or jumps out of, four wheel
drive low range.1) Transfer case not completely
engaged in 4L position.1) With the transmission in
NEUTRAL, or the clutch depressed
in the case of a manual
transmission and the vehicle moving
under 3-4 km/h (2-3 mph), shift the
transfer case to NEUTRAL and then
shift into the 4L position.
2) Shift linkage out of adjustment. 2) Adjust linkage.
3) Shift linkage loose or binding. 3) Tighten, lubricate, or repair
linkage as necessary.
4) Range fork damaged, inserts
worn, or fork is binding on the shift
rail.4) Disassemble unit and repair as
necessary.
5) Low range gear worn or
damaged.5) Disassemble unit and repair as
necessary.
