Disassembly (Rzeppa/DOJ Type)
1. Label and remove CV joint boot. Mark alignment of axle shaft to outer race of CV joint. Remove circlip and outer bearing race housing.
Mark alignment of inner race to shaft. Remove inner snap ring. Remove cage assembly. See Fig. 2
.
2. Pry ball bearings from bearing cage. Mark alignment of bearing cage to inner race. Rotate inner race about 30 degrees and remove from
cage assembly. If necessary, remove remaining boot.

Mark alignment of inner race to shaft. Remove snap ring and remove tripot assembly using a soft brass drift and hammer. See Fig. 2
.
Reassembly (Tripot Type)
Apply Grease (E43Z-19590-A ) to all areas of CV joint during reassembly. Reverse removal procedure, noting alignment marks made during
disassembly. Ensure chamfer on bearing cage faces snap ring. Lubricate outer race housing with 3.5 ounces (100 g) of grease. Installed length
of CV boot should be 3.5" (90 mm).
NOTE:Check old grease for contam ination by rubbing between two fingers. Any gritty feeling indicates

REASSEMBLY & INSTALLATION.
Disassembly
Separate intermediate shaft from axle shaft. Remove circlip from intermediate shaft and press off bearing and bracket assembly. See Fig. 4 .
Press bearing out of bracket. Inspect bracket for damage or wear and replace if necessary.
Reassembly
Press NEW bearing into bracket and install NEW seals. Install bearing and bracket assembly onto intermediate shaft. Install NEW circlip.
Assemble intermediate shaft to axle shaft.
Installation
Intermediate shaft and axle shaft are installed as an assembly. See FWD AXLE SHAFTS under REMOVAL, DISASSEMBLY,

ALTERNATOR & REGULATOR
1991 ELECT RICAL Alternators & Regulators
DESCRIPTION
Mitsubishi alternator is a 50-amp, conventional 3-phase, self-rectifying type unit, containing 6 diodes (3 main diodes and a smaller diode trio)
and a case-mounted Integrated Circuit (IC) regulator. A charge indicator light in the instrument panel indicates charging system mal fu n ct io n s.

NOTE:Before testing, check alternator wiring harness connections, drive belt tension and battery voltage.
Ensure battery cables and engine ground cable are clean and tight. Wait at least 30 seconds after
starting engine before m easuring voltage.
CAUT ION: DO NOT start engine with "L" and "S" term inal connectors disconnected from alternator. DO NOT allow
"L" term inal to contact ground while engine is running. See Fig. 2

Fig. 2: Identifying Alternator Test Terminals
Courtesy of FORD MOTOR CO.
1. Turn ignition switch to OFF position. Connect positive voltmeter lead wire to alternator "B" terminal and negative wire to ground. See
Fig. 2
. Ensure voltmeter indicates battery voltage. If voltmeter indicates zero volts, an open circuit exists in wire between "B" terminal
and battery positive terminal.
2. Remove voltmeter. Disconnect negative battery cable. Remove output lead from alternator terminal "B". Connect a 100-amp ammeter in
series between "B" terminal and disconnected output lead. Connect positive lead of ammeter to "B" terminal and negative lead to
disconnected output wire.
3. Connect voltmeter in parallel between alternator "B" terminal and battery positive terminal. Connect positive lead wire of voltmeter to
"B" terminal and negative lead wire to positive terminal of battery. Reconnect negative battery cable.
4. Install tachometer (if necessary) to monitor engine RPM. Start engine. Turn all lights and accessories on and depress brake pedal to load
system. Increase engine speed to 2500-3000 RPM. Ensure alternator output is at least 35 amps.
5. Observe voltmeter reading. If voltmeter indicates .2 volt and amperage output is at least 35 amps, system is okay. If voltage drop is
greater than .2 volt, wiring is defective between alternator "B" terminal and battery positive terminal.
6. Allow engine to idle. Turn off all accessories to remove load from system. Disconnect voltmeter. Connect negative lead of voltmeter to
ground. Using positive lead of voltmeter, backprobe "S" terminal connector at rear of alternator. See Fig. 2
.
7. Increase engine speed to 2500-3000 RPM. With no load on system, ammeter should read 5 amps or more. Battery voltage with no load
at indicated speed should be 14.1-14.7 volts. If amperage output is less than indicated with or without load and no external faults exist
in alternator circuit, overhaul or replace alternator.
BENCH TESTING
Rotor
Check continuity across rotor slip rings. If no continuity exists, replace rotor. Check continuity between individual slip rings and rotor
core/shaft. If continuity exists, rotor coil or slip ring is grounded. Replace rotor.
Stator
Ensure no continuity exists between stator coil leads and stator core. Check continuity between leads of stator coil. If continuity does not
exist, replace stator.
Brushes
Inspect brushes. Replace brushes if worn to wear line (leading edge of small square cast into brush). Use a spring pressure gauge to push each
NEW brush into its holder until .079" (2 mm) projects from holder. Spring force should be 10.6-15.6 oz. (.3-.4 kg). If spring force is not
within specification, replace brush spring.
Rectifier
1. Using an ohmmeter, check for continuity between positive side of diode leads and heat sink. If no continuity exists from any positive
diode lead to heat sink, replace rectifier assembly.
2. Reverse ohmmeter leads, and check for continuity between negative side of diodes and heat sink. If continuity exists from any n e ga t ive
diode lead to heat sink, replace rectifier assembly.
3. Check diode trio (smaller diodes between main diode leads) for continuity in both directions. Continuity should exist in one direction
only. If any diode shows continuity in both directions or does not show continuity in either direction, replace diode trio.

CAUTIONS & WARNINGS
BATTERY WARNING
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off all lights and accessories to avoid damaging the electrical system. Be sure to use
fuse with the correct indicated amperage rating. The use of an incorrect amperage rating fuse may result in a dangerous electrical system
overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning that brake pads need replacement.
CAUT ION: When battery is disconnected, vehicles equipped with com puters m ay lose m em ory data. When battery
power is restored, driveability problem s m ay exist on som e vehicles. T hese vehicles m ay require a
relearn procedure. See COMPUTER RELEARN PROCEDURES
article in the GENERAL INFORMAT ION
section.
