INSTALL
CAUTION: The hub/bearing retaining nut must be
tightened to but must not exceed its required
torque specification. The proper torque specifica-
tion of the retaining nut is critical to the life of the
hub bearing.
(1) Position hub/bearing assembly on rear spindle.
(2) Installa new hub nut(Fig. 101) and tighten
to a torque of 217 N´m (160 ft. lbs.).
(3) Install the dust cap, on the hub/bearing using a
soft faced hammer.

brake drum on the hub/bearing. On vehiclesequipped with rear disc brakes, install the rotor on
the hub/bearing.
(5) On disc brake equipped vehicles install the disc
brake caliper on the adapter. Install the 2 guide pin
bolts (Fig. 102) mounting the disc brake caliper to
the adapter. Tighten the guide pin bolts to a torque
of 22 N´m (192 in. lbs.). Refer To Rear Disc Brake
Service in this group of the service manual for the
required caliper installation procedure.
(6) Install rear wheel and tire assembly on vehicle.

BLEEDING MASTER CYLINDER
(1) Clamp the master cylinder in a vise. Attach
Bleeding Tubes, Special Tool 6802 to the master cyl-
inder (Fig. 108) and (Fig. 109). Position tubes so out-
lets of Bleeding Tubes will be below surface of brake

(2) Fill brake fluid reservoir with brake fluid con-
forming to DOT 3 specifications such as Mopar or an
Equivalent.
(3) Using a wooden dowel per (Fig. 110), depress
push rod slowly and then allow pistons to return to
released position. Repeat several times until all air
bubbles are expelled.

VACUUM BOOSTER
REMOVE
CAUTION: On ABS equipped vehicles, vacuum in
power booster must be pumped down before
removing master cylinder to prevent booster from
sucking in any contamination. This can be done
simply by pumping the brake pedal until a firm
pedal is achieved, with the ignition off.
(1) On ABS equipped vehicles, with engine not
running, pump the brake pedal until a firm pedal is
achieved (4-5 strokes).
(2) Remove vehicle wiring harness connector from
brake fluid level sensor located in master cylinder
brake fluid reservoir (Fig. 114).
(3) Disconnect the primary and secondary brake
tubes from the master cylinder (Fig. 115) and (Fig.
116). Install plugs at all open brake tube outlets on
master cylinder assembly.(4) On vehicles equipped with ABS, clean area
where master cylinder attaches to booster using a
suitable brake cleaner such as Mopar Brake Parts
Cleaner or an equivalent.
(5) Remove the 2 nuts (Fig. 117) attaching master
cylinder housing to power brake vacuum booster.
(6) Slide master cylinder assembly straight out of
the power brake vacuum booster.
CAUTION: On vehicles equipped with ABS, the
master cylinder is used to create the seal for hold-
ing vacuum in the power brake vacuum booster.
The vacuum seal in the front of the power brake
vacuum booster (Fig. 118) MUST be replaced when-
ever the master cylinder is removed from the power
brake vacuum booster.
(7) If vehicle is equipped with ABS, remove vac-
uum seal (Fig. 118) located in the front of the power

INSTALL
(1) Position power brake booster onto dash panel.
(2) Install and torque the 4 power brake vacuum
booster mounting nuts (Fig. 121) to 29 N´m (250 in.
lbs.) torque.
(3) Using lubriplate, or equivalent, coat the sur-
face of the brake pedal pin where it contacts the
brake vacuum booster input rod.
(4) Connect power brake vacuum booster input rod
to brake pedal pin and install a NEW retaining clip.
Use only a new retainer clip DO NOT USE the
old clip.
(5) Connect all previously removed vacuum hoses
onto power brake vacuum booster check valve (Fig.
119).
(6) If vehicle is equipped with ABS, install HCU.
Refer to Antilock Brake System Hydraulic Control
Unit in the Removal And Installation Section of the
Antilock Brake System Section of this service manual
for the required procedure.
CAUTION: When replacing the power brake vac-
uum booster on a vehicle equipped with ABS, a
NEW vacuum seal MUST be installed in the power
brake vacuum booster. Use only the procedure
detailed below for installing vacuum seal into power
brake vacuum booster. If old vacuum seal came out
with master cylinder when it was removed from
power brake vacuum booster, be sure it is removed
from master cylinder before attempting to install
master cylinder into power brake vacuum booster.
CAUTION: When lubricating master cylinder push
rod, use only Mopar Silicone Dielectric Compound.
Using any other type of grease or lubricant on the
push rod, will not provide adequate long term lubri-
cation of the push rod.
(7) Lubricate master cylinder push rod as indi-
cated in (Fig. 122) only usingMopar Dielectric
GreaseÐAnd No Substitutes.Refer to the Mopar
Chemicals Catalog to obtain the required lubricant.
(8) Install vacuum seal on master cylinder push
rod as shown with notches on vacuum seal pointing
toward master cylinder housing (Fig. 123). Then slide
vacuum seal onto master push rod until seal is
seated against master cylinder housing (Fig. 124)
before installing master cylinder on power brake vac-
uum booster.
CAUTION: If vehicle is equipped with ABS, be sure
the old vacuum seal is removed from power brake
vacuum booster before attempting to install master
cylinder and NEW vacuum seal. If vacuum seal is
not removed, refer to Master Cylinder Removal in
this section of the service manual for required vac-
uum seal removal procedure.
