ADJUSTMENTS & INSPECTION
WHEEL BEARING
1. Raise and support vehicle. Ensure parking brake is fully released. Remove wheel and dust cap. Rotate brake drum and ensure there is no
brake drag. Using a small cape chisel, raise the staked portion of the lock nut. Remove and discard lock nut.
2. Install new lock nut. To seat bearings, use a torque wrench and tighten lock nut to 18-21 ft. lbs. (25-29 N.m) while rotating brake drum.
After tightening, loosen lock nut until it can be turned by hand. Measure seal drag using an INCH lb. torque wrench on a lug nut at 12
o'clock position. Measure and record amount of force required to rotate brake drum.
3. To determine preload, add amount of seal drag to specified preload of 1.3-4.3 INCH lbs. (.15-.49 N.m). As an example, if seal drag
measures 2.2 INCH Lbs. (.25 N.m), this amount must be added to required preload.
4. Tighten wheel bearing lock nut a small amount. Using an INCH lb. torque wrench on a lug nut at 12 o'clock position, measure amo u n t
of pull required to rotate brake drum. Tighten attaching nut until specified amount of preload is measured with torque wrench. Stake
lock nut with a blunt chisel. Install grease cap and wheel.
REMOVAL & INSTALLATION
WHEEL BEARING
Removal
1. Raise and support vehicle. Ensure parking brake is fully released. Remove wheel and dust cap. Using a small cape chisel, raise staked
portion of lock nut. Remove and discard lock nut. Remove brake drum, bearing and hub assembly from spindle.
2. Pry out grease seal from hub and remove inner bearing. Bearings must be marked for reassembly reference if they are to be reused. Using
Slide Hammer (T50T-100-A), Bearing Cup Puller (T77F-1102-A) or proper sized brass drift and hammer, remove inner and outer
bearing races.
Installation
NOTE:Right side lock nut has left-hand threads. Left side lock nut has right-hand threads.
NOTE:Nut m ust be replaced if lock flange splits or cracks during staking process. DO NOT stake with a sharp
edged tool.

1. Using Installer (T77F-1217-A), Driver Handle (T80T-4000-W) or proper sized brass drift and hammer, install inner and outer bearing
races. Pack bearings and hub area with Lubricant (C1AZ-1959D-B, C, D or E).
2. Position inner bearing in bearing hub. Lubricate grease seal lips and install seal. Ensure bearings and hub have sufficient lubricant. Place
brake drum bearings and hub assembly on spindle. To prevent damage to grease seal and spindle threads, ensure hub is correctly
centered on spindle.
3. Install outer bearing, washer and new lock nut. Stake lock nut with a blunt chisel. Adjust bearing preload. See ADJUSTMENTS &
INSPECTION.

STRUTS
Removal & Installation (Capri)
1. Remove wheel, caliper and brake rotor. Remove trailing arm bolt and spindle-to-strut attaching bolts. Put index mark on strut rubber
mounting bracket. Remove upper strut attaching nuts from inside vehicle. Remove strut.
2. Compress strut coil spring with Spring Compressor (T18P-5310-A) or similar. Remove strut nut while spring is compressed. Remove
rubber mounting bracket, upper and lower spring seats. Slowly release coil spring and remove spring compressor. Remove coil spring,
dust boot and rebound bumpers. To install, reverse removal procedure.
Removal (Festiva)

LINE PRESSURE TEST SPECIFICATIONS (ASPIRE)
LINE PRESSURE TEST SPECIFICATIONS (ALL EXCEPT ASPIRE)
LINE PRESSURE CUT-BACK TEST
1. Connect oil pressure gauges to line pressure and governor pressure ports. See Fig. 6
. Position gauges so they can be seen from driver's
seat.
2. Connect a hand-held vacuum pump to vacuum modulator. See Fig. 6
. Position vacuum pump so it can be operated from driver's seat.
With shift lever in "D", gradually increase engine RPM and observe pressure gauge readings. Record results.
3. With shift lever in "D", gradually increase engine RPM, and apply 8 in. Hg to vacuum modulator. When line pressure reading suddenly
decreases, observe the governor pressure gauge. Refer to LINE PRESSURE CUT
-BACK TEST SPECIFICATIONS .
4. If governor pressure gauge readings are not within specifications, ensure rod in vacuum modulator is installed. If a rod is installed, rod
length may be incorrect or vacuum throttle valve is sticking. See VACUUM THROTTLE VALVE DIAPHRAGM (MODULATOR)

under TESTING.
LINE PRESSURE CUT-BACK TEST SPECIFICATIONS
GOVERNOR PRESSURE TEST
1. Attach oil pressure gauge to governor pressure check port. See Fig. 6
. Position gauge so that it may be seen from driver's seat. Shift
transaxle into "D" and road test vehicle.
2. Accelerate vehicle smoothly and record governor pressure readings at 20, 35 and 55 MPH. See GOVERNOR PRESSURE
SPECIFICATIONS . If pressure gauge readings are not within specifications, check for fluid leakage in line pressure hydraulic circuit
and/or governor pressure hydraulic circuit. Also check for a faulty governor.
GOVERNOR PRESSURE SPECIFICATIONS
REMOVAL & INSTALLATION
See the appropriate TRANSMISSION REMOVAL & INSTALLATION - A/T article in this section. Refer to the following menu:
TORQUE CONVERTER
The torque converter is a sealed unit and cannot be serviced. Check for cracked or worn ring in seal area. Measure bushing in converter boss.
If I.D. is larger than 2.090" (53.08 mm) on Aspire, 1.302" (33.075 mm) on Festiva and Tracer, replace torque converter. If metal particles are
found in ATF, replace torque converter. To clean torque converter, flush with solvent, drain and flush with ATF and drain ATF.
TRANSAXLE DISASSEMBLY
1. Remove torque converter. Attach transaxle to appropriate holding fixture. Remove park/neutral switch, kickdown solenoid and vacuum
modulator with rod. Remove oil dipstick and tube. Remove speedometer driven gear retaining bolt and lift out gear assembly. Remove
oil pump drive shaft and turbine shaft.
2. Remove oil pan. Remove valve body. DO NOT lose check ball and spring. Position transaxle with oil pump facing downward. With
flat-blade screwdriver inserted in wide slot between front clutch drum and sun shell, pry down on front clutch drum. Do this seve r a l
times as you rotate assembly 2 complete revolutions.
3. Using a feeler gauge, measure front clutch drum end play. See Fig. 7
. Check clearance of small slot between front clutch drum tabs and
