Chrysler Sebring, Stratus sedan, Sebring Convertible. Manual — part 650
STANDARD PROCEDURE - TIRE PRESSURE
FOR HIGH SPEED OPERATION
DaimlerChrysler Corporation advocates driving at
safe speeds within posted speed limits. Speed capac-
ity of a tire is a function of the tire speed rating,
inflation pressure and vehicle axle weight. Where
speed limits allow the vehicle to be driven at high
speeds, correct tire inflation pressure is very impor-
tant. Vehicles loaded to maximum capacity should
not be driven at continuous speeds over 120 km/h (75
mph). Never exceed the maximum speed capacity of
the tire. For information on tire identification and
speed ratings, (Refer to 22 - TIRES/WHEELS/TIRES
- DESCRIPTION).
STANDARD PROCEDURE - TIRE LEAK
REPAIRING
For proper repairing, a radial tire must be removed
from the wheel. Repairs should only be made if the
defect, or puncture, is in the tread area (Fig. 18). The
tire should be replaced if the puncture is located in
the sidewall.
Deflate tire completely before attempting to dis-
mount the tire from the wheel. Use a lubricant
such as a mild soap solution when dismounting
or mounting tire. Use tools free of burrs or sharp
edges which could damage the tire or wheel rim.
Before mounting tire on wheel, make sure all rust
is removed from the rim bead and repaint if neces-
sary.
Install wheel on vehicle, and progressively tighten
the 5 wheel nuts to a torque of 135 N·m (100 ft. lbs.).
CLEANING - TIRES
Before delivery of a vehicle, remove the protective
coating on the tires with white sidewalls or raised
white letters. To remove the protective coating, apply
warm water and let it soak for a few minutes. After-
wards, scrub the coating away with a soft bristle
brush. Steam cleaning may also be used to remove
the coating.
CAUTION: DO NOT use gasoline, mineral oil, oil-
based solvent or a wire brush for cleaning.
WHEELS
DESCRIPTION
Original equipment wheels are designed for proper
operation at all loads up to the specified maximum
vehicle capacity.
All models use steel or cast aluminum drop center
wheels. Every wheel has raised sections between the
rim flanges and rim drop well called safety humps
(Fig. 19).
Initial inflation of the tires forces the bead over
these raised sections. In case of air loss the raised
sections help hold the tire in position on the wheel
until the vehicle can be brought to a safe stop.
Cast aluminum wheels require special balance
weights to fit on the rim flange of the wheel and spe-
cial wheel clamps for the alignment equipment.
The wheel studs and nuts are designed for specific
wheel applications and must be replaced with equiv-
alent parts. Do not use replacement parts of lesser
quality or of a substitute design. All aluminum and
some steel wheels have wheel stud nuts with an
enlarged nose. This enlarged nose is necessary to
ensure proper retention of the wheels.

Before installing a wheel, remove any buildup of
corrosion on the wheel mounting surface.

ADVERSELY AFFECT THE SAFETY AND HANDLING
OF YOUR VEHICLE.
DIAGNOSIS AND TESTING - WHEEL
INSPECTION
Inspect wheels for:
• Excessive runout
• Dents, cracks or irregular bends
• Damaged wheel stud (lug) holes
• Air Leaks
NOTE: Do not attempt to repair a wheel by hammer-
ing, heating or welding.
If a wheel is damaged, an original equipment
replacement wheel should be used. When obtaining
replacement wheels, they must be equivalent in load
carrying capacity. The diameter, width, offset, pilot
hole and bolt circle of the wheel should be the same
as the original wheel.

WARNING: REPLACEMENT WITH USED WHEELS IS
NOT RECOMMENDED. THE SERVICE HISTORY OF
THE WHEEL MAY HAVE INCLUDED SEVERE TREAT-
MENT OR VERY HIGH MILEAGE. THE RIM COULD
FAIL WITHOUT WARNING.
CLEANING - ALUMINUM WHEEL CARE
Chrome plated and painted aluminum wheels
should be cleaned regularly using mild soap and
water to maintain their luster and to prevent corro-
sion.
Care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent
damage to the wheels. Any of the “DO NOT USE”
items listed below WILL damage chrome plated and
painted aluminum wheels.
DO NOT USE:
• any abrasive metal cleaner
• any abrasive cleaning pad or brush
• any cleaner that contains an acid (this will
immediately react with and discolor the chromium
surface)
• chrome polish (unless it is buffed off immedi-
ately after application)
• oven cleaner
• a car wash that uses carbide-tipped wheel clean-
ing brushes

REMOVAL
CAUTION: If a wheel mounting stud needs to be
replaced in the hub and bearing assembly, DO NOT
hammer the studs out of the hub flange. If a stud is
removed by hammering it out of the bearing flange,
damage to the hub and bearing assembly will occur
leading to premature bearing failure.
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - SERVICE PROCE-
DURE).
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove front disc brake caliper and adapter as
an assembly. Refer to Brakes.
(4) Remove any retainer clips, then remove brake
rotor form hub.
(5) Install a lug nut on wheel stud to be removed
from hub and bearing assembly, (Fig. 20) so threads
on stud are even with end of lug nut. Rotate hub so
stud requiring removal is aligned with notch cast
into front of steering knuckle. Install Remover, Spe-
cial Tool C-4150 on hub and bearing assembly flange
and wheel stud (Fig. 20).
(6) Tighten down on special tool, this will push the
wheel stud out of the hub and bearing flange.
INSTALLATION
CAUTION: If a wheel mounting stud needs to be
replaced in the hub and bearing assembly, DO NOT
hammer the studs out of the hub flange. If a stud is
removed by hammering it out of the bearing flange,
damage to the hub and bearing assembly will occur
leading to premature bearing failure.
(1) Install replacement wheel stud into flange of
hub and bearing assembly. Install washers on wheel
stud, then install a wheel lug nut on stud with flat
side of lug nut against washers (Fig. 21).
(2) Tighten the wheel lug nut, pulling the wheel
stud into the flange of the hub and bearing assembly.
When the head of the stud is fully seated against the
bearing flange, remove lug nut and washers from
wheel stud.
(3) Install brake rotor on front hub.
(4) Install disc brake caliper and adapter as an
assembly on knuckle. Refer to Brakes.
(5) Install front wheel and tire assembly. Install
front wheel lug nuts and torque to 135 N·m (100 ft.
lbs.).
(6) Lower vehicle.

REMOVAL
CAUTION: DO NOT hammer studs out of the hub
flange. If a stud is removed by hammering it out of
the bearing flange, damage to the hub and bearing
assembly will occur leading to premature bearing
failure.
(1) Remove the hub and bearing from the vehicle.
(Refer to 2 - SUSPENSION/REAR/HUB / BEARING -
REMOVAL)
CAUTION: Take care to keep hub and bearing
assembly from falling during stud removal. Damage
to the hub and bearing could result.
(2) Position the hub and bearing assembly under a
hydraulic press ram, supported by a 21 mm deep-
well impact socket under the stud to be replaced
(Fig. 22).
(3) Press the stud out of the hub flange and into
the socket well.
(4) Remove the hub and bearing assembly from
the press.
(5) Remove the stud from the socket.
INSTALLATION
CAUTION: DO NOT hammer studs into the hub
flange. If a stud is installed in such a manner, dam-
age to the hub and bearing assembly may occur
leading to premature bearing failure.
(1) Install wheel stud into stud hole in hub and
bearing assembly.
(2) Position the hub and bearing assembly face
down with stud pointing down into the well of the 21
mm socket. The hydraulic press ram must line up
with the stud (Fig. 23).
(3) Press the stud into the hub flange until it bot-
toms.
(4) Remove the hub and bearing assembly from
the press.
(5) Install the hub and bearing on the vehicle.
