HUB/BEARING
FRONT WHEEL DRIVE
REMOVE
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in the Lubri-
cation and Maintenance section of this service man-
ual for required lifting procedure.
(2) Remove wheel and tire.
(3) Remove brake drum from hub/bearing.
(4) Remove rear wheel speed sensor from rear hub/
bearing (Fig. 82). This will prevent damage to the
speed sensor during removal and installation of the
hub/bearing.The rear wheel speed sensor bolts
to the hub/bearing. It can not be removed
unless the speed sensor is removed first.
CAUTION: When working in the area of the rear
hub/bearing and when removing it from the rear
axle, care must be used so the teeth on the tone
wheel are not damaged. Damage to the teeth on the
tone wheel will result in false ABS cycling and cor-
rosion of the tone wheel.
(5) Remove the 4 bolts (Fig. 83) attaching the hub/
bearing to the rear axle.
CAUTION: Corrosion may occur between the hub/
bearing and the axle. If this occurs the hub/bearing
will be difficult to remove from the axle. If the hub/
bearing will not come out of the axle by pulling onit by hand, do not pound on the hub/bearing to
remove it from the axle. Pounding on the hub/bear-
ing to remove it from the axle will damage the hub/
bearing. This damage will result in noise or failure
of the bearing.
(6) If hub/bearing cannot be removed from the axle
by hand, use Remover Special Tool 8214 (Fig. 84) and
following procedure to press the hub/bearing out of
the axle.
(a) Place Special Tool 8214-1 over tone wheel
and against cast flange of hub/bearing (Fig. 84)
(b) Put a dab of grease in the bolt pilot hole on
the back of Special Tool 8214-1.
(c) Insert Special Tool 8214-2 into the hole in the
bottom of the end casting on the axle (Fig. 84).
Special Tool 8214-2 should be against and sup-
ported by the axle plate (Fig. 84) when pressing
the wheel bearing out of the axle.If Special Tool
8214-2 will not fit into the hole in the end
casting, file or grind the flashing from the
hole until tool fits properly.

CAUTION: Before moving vehicle, pump the brake
pedal several times to insure the vehicle has a firm
brake pedal to adequately stop vehicle.
(19) Road test vehicle to ensure proper operation
of the brake system.MASTER CYLINDER
CAUTION: Different types of master cylinders are
used on this vehicle. Vehicles equipped with trac-
tion control use a center port master cylinder. Vehi-
cles not equipped with traction control use a
compensating port master cylinder. Be sure to ver-
ify if the vehicle is equipped with traction control
and that the correct replacement master cylinder is
used. Also, vehicles that are equipped with four
wheel disc brakes have a master with a different
size piston bore than the other master cylinders. If
a new master cylinder is being installed, be sure
the correct master cylinder is used for the type of
brake system the vehicle is equipped with.
REMOVE
CAUTION: Vacuum in the power brake booster
must be pumped down (removed) before removing
master cylinder from power brake booster. This is
necessary to prevent the power brake booster from
sucking in any contamination as the master cylin-
der is removed. This can be done simply by pump-
ing the brake pedal, with the vehicle's engine not
running, until a firm feeling brake pedal is achieved.
(1) With engine not running, pump the brake
pedal until a firm pedal is achieved (4-5 strokes).
CAUTION: Before removing the master cylinder
filler tube from the brake fluid reservoir, the filler
tube, brake fluid reservoir and master cylinder must
be thoroughly cleaned. This must be done to pre-
vent dirt particles from falling into the brake fluid
reservoir and entering the brakes hydraulic system.
(2) Thoroughly clean all surfaces of the filler neck,
brake fluid reservoir, and master cylinder. Use only a
solvent such as Mopar Brake Parts Cleaner or an
equivalent.
(3) Remove master cylinder filler tube from brake
fluid reservoir by pushing down and rotating (Fig.
97). Then remove the cap from the removed filler
tube and install it on the master cylinder reservoir.
(4) Remove vehicle wiring harness connector, from
the brake fluid level sensor, in master cylinder brake
fluid reservoir (Fig. 98).
(5) Disconnect the primary and secondary brake
tubes from the master cylinder housing (Fig. 99).
Install sealing plugs in the open brake tube outlets
on master cylinder assembly.

REMOVAL AND INSTALLATION (Continued)

CAUTION: Before removing the master cylinder
from the power brake vacuum booster, the master
cylinder and vacuum booster must be thoroughlycleaned. This must be done to prevent dirt particles
from falling into the power brake vacuum booster.
(6) Clean the area where the master cylinder
assembly attaches to the power brake booster. Use
only a solvent such as Mopar Brake Parts Cleaner or
an equivalent.
(7) Remove the 2 nuts attaching the master cylin-
der assembly to the brake vacuum booster (Fig. 100).
(8) Slide master cylinder assembly straight out of
the power brake vacuum booster.
CAUTION: The master cylinder is used to create
the seal for holding vacuum in the power brake vac-
uum booster. The vacuum seal/boot on the master
cylinder MUST be replaced whenever the master
cylinder is removed from the power brake vacuum
booster.
(9) Remove the vacuum seal located on the mount-
ing flange of the master cylinder. The vacuum seal is
removed from the master cylinder bycarefullypull-
ing it away from the master cylinder.Do not
attempt to pry the seal off the master cylinder
by inserting a sharp tool between seal and mas-
ter cylinder casting.
BLEEDING MASTER CYLINDER
CAUTION: When clamping master cylinder in vise,
only clamp master cylinder by its mounting flange,
do not clamp on primary piston, seal or body of
master cylinder.
(1) Clamp the master cylinder in a vise using only
the mounting flange (Fig. 101).

REMOVAL AND INSTALLATION (Continued)

CAUTION: When installing the primary and second-
ary brake tubes on master cylinder, be sure brake
tubes do not contact any other components within
the vehicle and that there is slack in the flexible
sections of the tubes. This is required due to the
movement between the ABS hydraulic control mod-
ule (HCU) and the master cylinder, when the vehicle
is in motion.
(4) Connect the primary and secondary brake
tubes to master cylinder primary and secondary
ports (Fig. 99). Brake tubes must be held securely
when tightened to control orientation of flex section.
Then fully tighten the tube nuts to a torque of 17
N´m (145 in. lbs.).
(5) Install the vehicle wiring harness connector, on
the brake fluid level sensor in the master cylinder
brake fluid reservoir (Fig. 98).
(6) Install filler tube into the master cylinder fluid
reservoir (Fig. 97).
