FRONT AXLE BEARINGS

Front bearing preload is adjusted during bearing replacement by changing preload spacer. See FRONT WHEEL BEARINGS under
REMOVAL & INSTALLATION.

REAR AXLE BEARINGS

With bearings installed, tighten NEW lock nut to 18-22 ft. lbs. (24-30 N.m) while rotating wheel. Slightly loosen lock nut so it can be turned
by hand. Install a lug nut into axle hub. Attach an inch-pound torque wrench to lug nut at 12 o'clock position. Measure bearing preload.
Tighten lock nut until bearing preload, including seal drag, is 3.5-6.2 INCH lbs. (.4-.7 N.m). Stake NEW lock nut into notch on spindle.

TESTING

POWER BRAKE UNIT

Functional Test

1. Check master cylinder fluid level and hydraulic system for leaks. Place transaxle in Neutral or Park, turn ignition off and apply parking

brake. Pump brake pedal several times to eliminate vacuum from system, and hold pedal in depressed position.

2. Start and idle engine. If vacuum system is functioning properly, pedal moves downward under constant foot pressure. If no pedal motion

is felt, vacuum booster is not functioning properly. Go to next step.

3. Run engine for at least one minute and turn ignition off. Depress brake pedal several times. Booster is okay if pedal stroke is long at first

and becomes shorter with each stroke. If stroke does not shorten, check for a damaged, restricted or improperly connected check valve
vacuum hose. Repair and recheck. Go to next step.

4. Restart engine. Depress and hold pedal down. Turn ignition off and wait 30 seconds. Booster is okay if pedal height remains unchanged.

If pedal height changes, check for a damaged, restricted or improperly connected check valve or vacuum hose. Go to next step.

5. Connect a pressure gauge to master cylinder output line. Connect a vacuum gauge to booster and a pedal depression force gauge to

brake pedal. Bleed air from pressure gauge. Start engine. When vacuum gauge reads 19.7 in. Hg, turn ignition off. Watch vacuum gauge
for 15 seconds. Booster is okay if vacuum gauge reads 18.7-19.7 in. Hg. If vacuum gauge reads less than 18.7 in. Hg, proceed to next
step.

6. Restart engine. Apply and hold 44 lbs. (196 N) force to brake pedal. When vacuum gauge reading reaches 19.7 in. Hg, turn ignition off.

Watch vacuum gauge for 15 seconds. Booster is okay if vacuum gauge reads 18.7-19.7 in. Hg. If vacuum gauge reads less than 18.7 in.
Hg, proceed to next step.

7. With engine stopped and vacuum gauge at zero, check pressure gauge. Apply 44 lbs. (196 N) force to brake pedal and check pressure

gauge. Booster is okay if pressure gauge reads 256 psi (18 kg/cm

2

).

8. Remove pedal force and start engine. When vacuum gauge reaches 19.7 in. Hg, apply 44 lbs. (196 N) force to pedal. Booster is okay if

pressure gauge read 768 psi (54 kg/cm

2

).

Diagnosis

If booster does not function properly, see

Fig. 3

.

NOTE:

Axle lock nut on right side has left-hand threads. Always install NEW lock nut when removed.

NOTE:

Inspect all vacuum hoses for holes, collapsed areas and secure connections. Ensure all unused
vacuum ports are capped.

CHECK VALVE

On Capri, check valve is located on power brake unit. On Festiva, check valve is located in vacuum hose connecting power booster to intake
manifold. Disconnect check valve vacuum hose from manifold. Alternately apply vacuum and pressure to hose. Ensure air flows only toward
engine. If pressure by-passes check valve or if check valve blocks vacuum, replace hose and check valve.

2. Tighten center bolt from spacer selector set, in increments, to 36, 72, 108 and finally 145 ft. lbs. (49, 98, 147 and 196 N.m). Each time

center bolt is tightened, seat bearings by rotating hub by hand. Using an inch-pound torque wrench, measure torque required to turn
center bolt. Ensure torque reading is taken just as wrench starts to rotate.

3. Preload spacer thickness is correct if torque wrench indicates 2.2-16 INCH lbs. (.25-1.8 N.m). If measurement indicates less than 2.2

INCH lbs. (.25 N.m), a thinner spacer must be installed. If measurement indicates more than 16 INCH lbs. (1.8 N.m), a thicker spacer
must be installed.

4. Bearing spacers are available in various thicknesses. See PRELOAD SPACER AVAILABILITY table. Changing spacer thickness one

number changes bearing preload 1.8-3.5 INCH lbs. (.2-.4 N.m). Ensure correct spacer is installed and preload is within specification.
Remove preload spacer selector set.
