1900 MITSUBISHI DIAMANTE Repair Manual

7-10 DRIVETRAIN
The automatic transaxle allows engine torque and
power to be transmitted to the front wheels within a
narrow range of engine operating speeds. It will allow
the engine to turn fast enough to produce plenty of
power and torque at very low speeds, while keeping it
at a sensible rpm at high vehicle speeds (and it does
this job without driver assistance). The transaxle uses
a light fluid as the medium for the transmission of
power. This fluid also works in ths operation of vari-
ous hydraulic control circuits and as a lubricant. Be-
cause the transaxle fluid performs all of these func-
tions, trouble within the unit can easily travel from one
part to another For this reason, and because of the
complexity and unusual operating principles of the
transaxle, a very sound understanding of the basic
principles of operation will simplify troubleshooting

ADJUSTMENTS
Shifter Control Cable Adjustment
1. The shifter cable adjustment is done at the
neutral safety switch (inhibitor switch). Locate the
switch on the transaxle and note the alignment holes
in the arm and the body of the switch. Place the se-
lector lever in N. Place the manual lever of the
transaxle in the neutral position.
2. Check alignment of the hole in the manual
control lever to the hole in the inhibitor switch body.
If the holes do not align, adjustment is required.
3. To adjust, loosen the nut on the cable end and
pull the cable end by hand until the alignment holes
match. Tighten the nut. Check that the transaxle
shifts and conforms to the positions of the selector
lever.
Throttle Valve Cable
The throttle valve adjustment applies only to the
1990-96 Mirage.
1. Place selector lever and manual control lever
in N position.
2. Loosen adjusting nut. While lightly pulling on
control cable tighten mounting nut to 7-10 ft. Ibs.
(X-14 Nm).
3. When adjustment is complete, be sure selector
lever is still in the N position. Verify all functions
correspond to the position indicated on the selector
lever.

1. Disconnect the negative battery cable. Raise
the vehicle and support safely.
2. The rear driveshaft is a 3-piece unit, with a
front, center and rear propeller shaft. Remove the
nuts and msulators from the center support bearing.
Work carefully. There will be a number of spacers
which will differ from vehicle to vehicle. Check the
number of spacers and write down their locations for
reference during reassembly.
3. Matchmark the rear differential companion
flange and the rear driveshaft flange yoke. Remove
the companion shaft bolts and remove the driveshaft,
keeping it as straight as possible so as to ensure that
the boot is not damaged or pinched. Use care to keep
from damaging the oil seal in the output housing of
the transfer case.
*Damage to the boot can be avoided and
work will be easier if a piece of cloth or simi-
lar material is inserted in the boot.
4. Do not lower the rear of the vehicle or oil will

keep dirt out.
To install: 5. Position the driveshaft in the vehicle, making
sure to align the matchmarks at the rear yoke.

5. Once all bearings are removed, remove the
journal.
To install:
6. Apply multi-purpose grease to the shafts,
grease sumps, dust seal lips and needle roller bear-
ings of the replacement U-joint Do not apply exces-
sive grease Otherwse, faulty fitting of bearing caps
and errors in selection of snaprings may result.
7. Press fit the journal bearings to the yoke using
a C-clamp as follows:
a. Install a solid base onto the bottom of the
C-clamp.
b. Insert both bearings into the yoke. Hold
and press fit them by tightening the C-clamp.
c. Install snaprings of the same thickness
onto both sides of each yoke.
d. Press the bearing and journal into one side, using a brass bar with diameter of 0.59 in.
(15mm).
8. Measure the clearance between the snapring
and the groove wall of the yoke with a feeler gauge. If
the clearance exceeds 0.0008-0.0024 in.
(0.02-O.O6mm), the snap rings should be replaced.
DRIVESHAFT BALANCING
Driveshaft balancing is a process best left for a
professional wrth the proper equipment. Makeshift
methods using hose clamps or similar devices can
work, but the process of correcting the imbalance in
this manner is very tough and extremely time con-
suming.
Many machine shops can balance driveshafts;
some parts stores and jobbers can also balance dri-
veshafts using outside contractors.
REMOVAL&INSTALLATION
1. Place matmg marks on the companron flange
and the Lobro joint assembly
2. Remove the Lobro joint installation bolts.
Separate the Lobro joint from the companion flange.
3. Place mating marks on the center yoke and
center propeller shaft, and the companion flange and
the rear propeller shaft.
4. Remove the self-locking nuts. Remove the
center yoke and companion flange. 5. Place mating marks on the center bearing as-
sembly front bracket and the center propeller shaft,
and the center bearing assembly rear bracket and the
rear propeller shaft. Remove the center bearing
bracket.
*The mounting rubber can not be removed
from the center bearing bracket.
6. Pull out the front and rear center bearings
with a commercially available puller
To install:
7. Apply multi-purpose grease to the center
bearing front and rear grease grooves and to the dust
seal lip Be sure to fit the bearing into the rubber
mount groove on the center bearing bracket.
*Face the bearing dust seal to the side of
the center bearing bracket mating mark.
8. Assemble the center bearing to the center
propeller shaft and rear propeller shaft. Face the side
onto which the center bearing bracket mating marks
IS placed and the dust seal is installed toward the
side of the center propeller shaft and rear propeller
shaft.
9 Apply a thin and even coat of the grease, en-
closed with the repair kit, to the rubber packing on
the companion flange. Align the mating marks on the
center propeller shaft and the companion flange, then
press fit the center bearing with self-locking nuts.
10 Install the Lobro joint assembly installation
bolts. Secure the companron flange and Lobro joint
assembly with the installation bolts Check for grease
leakage from the Lobro joint boot and companion
flange installabon parts.
The only model covered by this manual equipped
with a rear axle differential is the 1990-93 AWD
Galant.

4 Remove the rear driveshaft from the vehicle.
5. If necessary, carefully pry the oil seal from the
rear differential using a flat tipped prying tool.
To install:
6. Install a new oil seal into the rear differential
housing using proper size driver.
7. Replace the circlip and install the rear drive-
shaft to the differential case. Make sure it snaps in
place.
8. Install the companion flange bolts and tighten
to 40-47 ft. Ibs. (55-65 Nm).
9. Check the fluid level in the rear differential.

REMOVAL &INSTALLATION
1. Disconnect the negative battery cable.
2. Raise and support the vehicle safely.
3 Remove the tire and wheel assembly from the
vehicle.
4 If equipped with ABS, remove the rear wheel
speed sensor.
*Be cautious to ensure that the tip of the
pole piece on the rear speed sensor does not
come in contact with other parts during re-
moval. Sensor damage could occur.
5. Remove the rear caliper and support assem-
bly out of the way. Remove the brake disc.
6. Remove the driveshaft and companion flange
installation bolts, nuts and washers. Move the end of
shaft slightly to access the self-locking nut.
7. Using axle holding tool MBSbll-01 or
equivalent, secure the rear axle shaft in position, then
remove the self-locking nut.
8. Using puller and adapter MBSbll-01 and
MB9b41-01 or equivalents, remove the rear axle
shaft from the trailing arm
9. If equipped with ABS, remove the rear rotor
from the axle assembly using collar and press. The
rotor is a press fit.
