Chrysler New Yorker. Manual — part 8
avoid damage to speed sensor by outer C/V
joint when hub and bearing is removed.
(6) Carefully, remove sensor head from steering
knuckle. If the sensor has seized, due to corrosion,
DO NOT USE PLIERS ON SENSOR HEAD. Use
a hammer and punch (Fig. 18) to tap edge of sensor
ear, rocking sensor side to side until free.
(7) Remove the hub and bearing to stub axle
retaining nut (Fig. 19).
(8) Remove the 3 steering knuckle to hub and
bearing assembly attaching bolts (Fig. 20).
CAUTION:
If metal seal (Fig. 21) on hub and bear-
ing assembly is seized to steering knuckle and
becomes dislodged on hub and bearing assembly
during bearing removal the hub and bearing assem-
bly MUST not be reused and MUST be replaced with
a new hub and bearing assembly. Also if flinger
disc (Fig. 21) becomes damaged (bent or dented)
during removal, hub and bearing assembly must be
replaced with a new hub and bearing assembly.
(9) Remove hub and bearing assembly from steer-
ing knuckle. It is removed by sliding it straight out
of steering knuckle and off end of stub axle (Fig. 22).
If hub and bearing assembly will not slide out of
knuckle, insert a pry bar between hub and bearing
assembly and steering knuckle (Fig. 23) and gently
pry hub and bearing from knuckle. If stub shaft is
frozen to hub and bearing assembly tap end of stub
shaft with soft face hammer to free it from hub and
bearing spline.
(10) Remove the ball joint stud to steering knuckle
attaching nut and bolt (Fig. 24).

CAUTION:
When lower control arm is separated
from steering knuckle, do not let ball joint seal hit
up against steering knuckle. If ball joint seal hits
steering knuckle, seal damage may occur. If ball
joint seal becomes torn, replace seal before assem-
bling lower control arm to knuckle.
(11) Carefully insert a pry bar between lower con-
trol arm and steering knuckle (Fig. 25). Push down
on pry bar to separate ball joint stud from steering
knuckle (Fig. 25).

REMOVAL AND INSTALLATION (Continued)
CAUTION:
The strut assembly to steering knuckle
bolts are serrated where they go through strut
assembly and steering knuckle. When removing
bolts, turn nuts off bolts DO NOT TURN BOLTS IN
STEERING KNUCKLE. If bolts are turned damage to
steering knuckle will result.
(12) Remove
the
strut
assembly
to
steering
knuckle attaching bolts (Fig. 26).
(13) Remove the steering knuckle from the vehicle.
INSTALL
(1) Install steering knuckle on ball joint stud.
Install steering knuckle to lower ball joint attaching
bolt and nut into steering knuckle (Fig. 24). Tighten
the attaching bolt to a torque of 55 N·m (40 ft. lbs.).
(2) Position steering knuckle into strut assembly.
CAUTION:
The strut assembly to steering knuckle
bolts are serrated were they go through strut
assembly and steering knuckle. When installing
bolts, turn nuts onto bolts DO NOT TURN BOLTS IN
STEERING KNUCKLE. If bolts are turned damage to
steering knuckle will result.
(3) Install the strut assembly to steering knuckle
attaching bolts (Fig. 26). Install nuts on attaching bolts
(Fig. 26). Tighten the strut clevis to steering knuckle
attaching bolt nuts to a torque of 203 N·m (150 ft. lbs.).
CAUTION:
Hub and bearing assembly mounting
surfaces on steering knuckle and halfshaft (Fig. 27)
must be smooth and completely free of foreign
material or nicks.
CAUTION:
When
installing
hub
and
bearing
assembly into steering knuckle, be careful not to
damage the flinger disc (Fig. 21) on hub and bear-
ing assembly. If flinger disc becomes damaged, hub
and bearing assembly MUST not be used and MUST
be replaced with a new hub and bearing assembly.
(4) Install hub and bearing assembly onto stub
shaft and into steering knuckle until squarely seated
on face of steering knuckle.
(5) Install the 3 steering knuckle to hub and bear-
ing assembly attaching bolts (Fig. 20). Equally
tighten all 3 mounting bolts until hub and bearing
assembly is squarely seated against front of steering
knuckle. Then tighten all 3 hub and bearing assembly
mounting bolts to a torque of 110 N·m (80 ft. lbs.).
CAUTION:
The hub and bearing assembly to stub
shaft retaining nut (Fig. 19) is a prevailing torque
nut and can not be reused. A NEW retaining nut
MUST be used when assembled.
(6) Install a NEW hub and bearing assembly to
stub shaft retaining nut (Fig. 19). Tighten, but do
not torque the hub nut at this time.
(7) Coat speed sensor head with High Temperature
Multipurpose E.P. Grease before installing into the
steering knuckle. Install speed sensor head into
steering knuckle. Install screw and tighten to a
torque of 7 N·m (60 in. lbs.).
(8) Install the braking disk back on the hub and
bearing assembly (Fig. 17).
(9) Install front brake caliper on steering knuckle.
Refer to Front Disc Brake Service in the Brake Sec-
tion of this service manual for caliper installation
procedure. Install the caliper to steering knuckle
attaching bolts (Fig. 16) and tighten them to a torque
of 19 N·m (168 in. lbs.).
(10) Install wheel and tire assembly on vehicle.
Tighten the wheel mounting stud nuts in proper
sequence until all nuts are torqued to half specifica-
tion. Then repeat the tightening sequence to the full
specified torque of 129 N·m (95 ft. lbs.).
(11) Lower vehicle to the ground.

CAUTION:
When torquing hub and bearing assem-
bly to stub shaft retaining nut, do not exceed the
maximum torque of 163 N·m
6
14 N·m (120 ft. lbs.
6
10 ft. lbs.). If the maximum torque is exceeded
this may result in a failure of the drive shaft.
(12) Apply the brakes to keep the vehicle from
moving, then tighten the NEW stub axle retaining
nut to a torque of 163 N·m
6 14 N·m (120 ft. lbs. 6
10 ft. lbs.) (Fig. 28).
HUB AND BEARING
REMOVE
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in the Lubrica-
tion and Maintenance section of this manual, for the
required lifting procedure to be used for this vehicle.
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove the 2 guide pin bolts mounting the cal-
iper assembly to the steering knuckle (Fig. 29).
Remove the caliper from the front steering knuckle.
Refer to Disc Brake Caliper in the Removal And
Installation Section in the Brake Group of this ser-
vice manual for the caliper removal procedure.
(4) Remove rotor from hub by pulling it straight
off wheel mounting studs (Fig. 30).
(5) Remove the hub and bearing retaining nut
