Chrysler Sebring, Stratus sedan, Sebring Convertible. Manual — part 274
(7) If vehicle is equipped with antilock brakes,
remove bolts and wheel speed sensor heads from
both rear knuckles.
(8) Remove both rear disc brake calipers from
knuckles and hang out of way using wire or cord.
(Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/
BRAKE PADS/SHOES - REMOVAL). Do not allow
calipers to hang by brake hoses.
(9) Release brake tubing from clips on top of cross-
member.
(10) On the side of the vehicle requiring control
arm removal, separate the control arm ball joint from
the rear knuckle using following procedure:
(a) Back off nut retaining upper control arm ball
joint to knuckle until nut is even with end of stud.
This action will help avoid damaging the stud
threads when the stud is released from the knuckle
in the following step.
(b) Remove ball joint stud from knuckle using
Puller, Special Tool, CT- 1106 (Fig. 33).
(c) Remove nut retaining upper control arm ball
joint to knuckle.
(11) Position a transmission jack and wooden block
under the center of the rear suspension crossmember
to support and lower crossmember during removal
(Fig. 34).
(12) Remove the 4 bolts (Fig. 35) attaching rear
suspension crossmember to rear frame rails.
CAUTION: When lowering rear suspension cross-
member do not put a strain on the rear brake flex
hoses.

(13) Lower the rear suspension crossmember far
enough to access the upper control arm pivot bar to
crossmember attaching bolts.
(14) Remove the 2 bolts attaching the upper con-
trol arm to the rear suspension crossmember (Fig.
36).
(15) Remove the upper control arm from the rear
suspension crossmember.
(16) Transfer any required components to the
replacement control arm.
DISASSEMBLY - UPPER BALL JOINT
The rear upper control arm must be removed from
the vehicle for replacement of the ball joint. (Refer to
2 - SUSPENSION/REAR/UPPER CONTROL ARM -
REMOVAL)
(1) Position Receiving Cup, Special Tool 6758, to
support control arm when removing ball joint assem-
bly (Fig. 37). Install Remover/Installer, Special Tool
6804 on top of ball joint assembly (Fig. 37).
(2) Using an arbor press, press the ball joint
assembly out of the control arm.
INSPECTION
Inspect the control arm for physical damage. If it is
determined that the upper control arm is broken or
bent, the upper control arm must be replaced. The
rear suspension upper control arm is not a repairable
component and no attempt is to be made to repair or
to straighten it. The upper control arm must be
replaced if found to be damaged in any way.
Inspect the control arm pivot bushings for deterio-
ration. If found to need replacement, the upper con-
trol arm is to be replaced.
The rear control arm, control arm bushings, and
pivot bar are serviced as a complete assembly on this
vehicle. Do not attempt to disassemble the control
arm from the pivot bar to service the rear control
arm bushings.
The only component on the upper control arm that
is serviceable is the rear upper ball joint and its seal.
ASSEMBLY - UPPER BALL JOINT
(1) By hand, position ball joint assembly into ball
joint bore of control arm. Be sure ball joint assembly
is not cocked in the bore of the control arm. This will
cause binding of the ball joint assembly when being
pressed into lower control arm.
(2) Position assembly in an arbor press with
Receiving Cup, Special Tool 6758, supporting lower
control arm (Fig. 38). Then install Remover/Installer,
Special Tool 6804, on the top of the ball joint assem-
bly (Fig. 38).
CAUTION: When installing the ball joint in the upper
control arm, do not press the ball joint into the con-
trol arm all the way. The lip on the ball joint must
not touch the surface of the control arm. Refer to
Step 3 below when installing the ball joint.
(3) Carefully align all pieces. Using the arbor
press, press the ball joint into the control arm until a
gap of 3 mm (1/8 inch) is between lip on ball joint
and surface of lower control arm.

(4) Reinstall the control arm on the vehicle. (Refer
to 2 - SUSPENSION/REAR/UPPER CONTROL ARM
- INSTALLATION)
INSTALLATION
(1) Align the pivot bar on the upper control arm
with the mounting holes in the rear suspension
crossmember. Install the pivot bar attaching bolts
(Fig. 36). Tighten the 2 pivot bar attaching bolts to a
torque of 108 N·m (80 ft. lbs.).
(2) Using transmission jack, raise rear suspension
crossmember up to the rear frame rails and loosely
install the 4 attaching bolts (Fig. 35).
(3) Position an appropriate size drift into the posi-
tioning hole in each side of rear suspension cross-
member and crossmember locating holes in frame
rails of the vehicle (Fig. 39). This is required to prop-
erly position rear suspension crossmember to the
body of the vehicle. Tighten the 4 crossmember to
frame rail attaching bolts to 108 N·m (80 ft. lbs.).
Remove drifts from rear suspension crossmember.
(4) Remove transmission jack supporting rear sus-
pension crossmember.
(5) Install upper ball joint stud in knuckle. Install
and tighten the ball joint stud nut to a torque of 27
N·m (20 ft. lbs.).
(6) Install the brake tubing above the rear suspen-
sion crossmember into the routing clips on top of the
crossmember.
Install rear brake calipers onto rear knuckles.
(Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/
BRAKE PADS/SHOES - INSTALLATION)
(7) If vehicle is equipped with antilock brakes,
attach wheel speed sensor heads to both rear knuck-
les. Tighten sensor mounting bolts to a torque of 8
N·m (75 in. lbs.).
(8) If vehicle is equipped with antilock brakes,
install routing clips for wheel speed sensor cables
onto brackets on both upper control arms (Fig. 32).
Securely tighten routing clip attaching bolts.
(9) Install muffler support bracket on rear frame
rail (Fig. 30).
(10) Install rear exhaust pipe hanger on rear sus-
pension crossmember (Fig. 31).
(11) Install the shock absorber clevis brackets on
the rear knuckles (Fig. 29). Tighten the shock
absorber mounting bolts to a torque of 95 N·m (70 ft.
lbs.).
(12) Install wheel and tire assembly on vehicle.
Progressively tighten the wheel mounting nuts in
crisscross sequence until all nuts are torqued to half
specification. Then repeat the tightening sequence to
the full specified torque of 135 N·m (100 ft. lbs.).
(13) Lower vehicle.
(14) Check and reset if required, rear wheel Cam-
ber and Toe to preferred specifications (Refer to 2 -
SUSPENSION/WHEEL ALIGNMENT - STANDARD
PROCEDURE).

WHEEL ALIGNMENT
DESCRIPTION - WHEEL ALIGNMENT
Vehicle wheel alignment is the positioning of all
interrelated front and rear suspension angles. These
angles affect the handling and steering of the vehicle
when it is in motion. Proper wheel alignment is
essential for efficient steering, good directional stabil-
ity, and proper tire wear.
The method of checking a vehicle’s front and rear
wheel alignment varies depending on the manufac-
turer and type of equipment used. The manufactur-
er’s instructions should always be followed to ensure
accuracy
of
the
alignment,
except
when
DaimlerChrysler Corporation’s wheel alignment spec-
ifications differ.
On this vehicle, the suspension angles that can be
adjusted are as follows:
Front
• Camber (using special procedure)
• Toe
Rear
• Camber
• Toe
Check the wheel alignment and make all wheel
alignment adjustments with the vehicle standing at
its proper curb height specification. Curb height is
the normal riding height of the vehicle. It is mea-
sured from a certain point on the vehicle to the
ground or a designated area while the vehicle is sit-
ting on a flat, level surface. Refer to Curb Height
Measurement in this section for additional informa-
tion.
Typical wheel alignment angles and measurements
are described in the following paragraphs.
CAMBER
Camber is the inward or outward tilt of the top of
the tire and wheel assembly (Fig. 1). Camber is mea-
sured in degrees of angle relative to a true vertical
line. Camber is a tire wearing angle.
• Excessive negative camber will cause tread wear
at the inside of the tire.
• Excessive positive camber will cause tread wear
on the outside of the tire.
