Chrysler Crossfire. Manual - part 8

INSPECTING AND ADJUSTING VEHICLE LEVEL AT FRONT AND REAR AXLES

1. Observe the general information on chassis alignment inspection. (Refer to 2 - SUSPENSION/WHEEL ALIGN-

MENT - STANDARD PROCEDURE).

2. Inspect the vehicle level at the front axle by performing the following:

•

Insert measuring device between the retaining bolts of the lower control arm bearing.

•

Position the contact arm of measuring device on the control arm and read off the plumb value of vehicle level,
viewed from the center of the vehicle. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PRO-
CEDURE).

3. Inspect the vehicle level at the rear axle by performing the following:

•

Loosen right rear frame brace and swivel to one side.

•

Position contact arm on the rear axle shaft and read off the plumb value of the vehicle level, viewed from the
center of the vehicle. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).

Note: If the vehicle level at the front or rear axle is outside the tolerance, adjust the vehicle level by chang-
ing the springs or spring rubber mounts.

4. Adjust the vehicle level at the front and rear axles.

INSPECTING AND ADJUSTING VEHICLE LEVEL AT FRONT AND REAR AXLES
WITH AN ELECTRONIC INCLINOMETER

1. Observe the general information on chassis alignment inspection. (Refer to 2 - SUSPENSION/WHEEL ALIGN-

MENT - STANDARD PROCEDURE).

CAUTION: The measuring plate is magnetic. Information on data media, e.g. floppy disks, credit cards, etc.,
could be rendered unusable.

Note: Be sure to clean measurement points on the lower wishbone.

Note: Remove any metal shavings on the measuring plate.

2. Install the measuring plate in the recessed area in the lower control arm. The groove in the measuring plate

should be at an angle of 90° towards the direction of travel.

3. Inspect the vehicle level at the front axle via control arm inclination. (Refer to 2 - SUSPENSION/WHEEL ALIGN-

MENT - STANDARD PROCEDURE).

4. Inspect the vehicle level at the rear axle via the rear axle shaft inclination. (Refer to 2 - SUSPENSION/WHEEL

ALIGNMENT - STANDARD PROCEDURE).

5. Adjust the vehicle level at the front and rear axles. If the vehicle level is outside the allowed tolerance at the front

or rear axle, perform the following:

•

Adjust the vehicle level by changing the springs or the spring rubber mounts. (Refer to 2 - SUSPENSION/
WHEEL ALIGNMENT - STANDARD PROCEDURE).

CHECKING AND ADJUSTING FRONT AXLE CAMBER AND CASTER

CHECKING

1. Observe the general information on chassis alignment check. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT

- STANDARD PROCEDURE).

2. Check the vehicle level at the front and rear axles. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STAN-

DARD PROCEDURE).

3. Check the vehicle level at the front and rear axles with an electronic inclinometer and adjust if necessary. (Refer

to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).

4. Check the camber and assign to tabular value. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - SPECIFICA-

TIONS).

Note: Measure with the wheels turned to 20°.

5. Check the caster and assign to tabular value. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - SPECIFICA-

TIONS).

ADJUSTING

Note: Vehicles are delivered from the factory with pre-set caster, camber, and toe settings. When aligning a
vehicle with factory settings, Eccentric Repair Bolts must be installed in order to adjust caster or camber.
Toe is the only adjustment that can be made without installing the Eccentric Repair Bolts.

1. Raise and support the vehicle.

2. Cover all the attached parts remaining in the vehicle. (area to be repaired)

WARNING: RISK OF INJURY WITH TRAPPED OR CRUSHED FINGERS WHEN WORKING ON SPRINGS OR
SPRING-LOADED COMPONENTS.

CAUTION: Use only approved tensioning devices; additionally shield off hazardous area if necessary.

CAUTION: Inspect special tools for damage and proper operation (visual inspection). Wear protective
gloves.

Note: Inspect for prior installation of the eccentric
repair bolt.

3. For camber, compress the front spring (1). (Refer

SUSPENSION/FRONT/SPRING

REMOVAL).

4. Install the repair bolt (2). Screw on the nut from the

repair kit as far as it will go, but do not tighten it so
that the rubber mount on the wishbone can turn
when

the

suspension

compressed

and

rebounded.

5. Release the front spring (1).

6. Lower the vehicle and settle the suspension by

pulling and pushing firmly several times.

Note: Inspect for prior installation of the eccentric
repair bolt.

7. For caster, compress the front spring (2). (Refer to

2 - SUSPENSION/FRONT/SPRING - REMOVAL).

8. Install the repair bolt (1). Screw on the nut from the

repair kit as far as it will go, but do not tighten it so
that the rubber mount on the wishbone can turn
when

the

suspension

compressed

and

rebounded.

9. Release the front spring (2).

10. Lower the vehicle and settle the suspension by

pulling and pushing firmly several times.

WHEEL ALIGNMENT

Note: The vehicle level must correlate with the dimension established on the initial measurement.

11. Recheck the vehicle level at the front axle after adjusting the camber and caster.

•

Vehicle level at the front axle. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).

•

With an electronic inclinometer. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCE-
DURE).

Note: After repairing, the adjusting screw must not be turned by the shims, and must be countered when
tightening the hexagon nut.

12. Tighten the nut from the repair kit to 120 N·m (88 ft. lbs.)

13. Adjust the rear axle toe. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).

14. Adjust the front axle toe. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).

STANDARD PROCEDURE - CHECKING AND ADJUSTING FRONT TOE-IN

1. Set the steering wheel in the center position.

Note: The steering gear is in the center position
when the separating joint of the steering coupling
and the marking notch on the steering gear are
above each other. Offset the steering wheel by a
maximum of one tooth, if necessary.

2. Check the center position of the steering gear and

steering wheel.

Note: The flexible mount of the control arms
results in a correspondingly large toe-in value
which reduces to the correct dimension in the
ready-to-drive condition

3. Install a steering wheel spreader on the inside of

the steering wheel in the forward direction of travel.

Note: After adjusting toe-in, check rubber boot on
inner joint for twisting.

4. Adjust the toe-in by rotating the tie rods. Tighten the lock nut to 50 N·m (37 ft. lbs.).

•

Negative Toe (Toe Out) 1 > 2.

•

Positive Toe (Toe In) 1 < 2.

STANDARD PROCEDURE - CHECKING TOE-OUT ON TURNS

1. Check and adjust the toe-in at the front axle. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD

PROCEDURE).

2. Check the toe-out on turns. To check steering geometry measure toe-out on turns. This is the difference in the

wheel angle between the wheel on the outside of a curve and the wheel on the inside of a curve when the wheel
on the inside of the curve is turned 20°. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PRO-
CEDURE).

•

Toe-in not adjusted with steering gear in straight ahead position resulting in unequal tie rod lengths.

•

Steering knuckle, steering column or steering intermediate arm bent.

•

On vehicles involved in an accident excessive deviations in the front end (longitudinal frame member, frame
cross member, wheelhouse, or the cowl/dash panel) which have a negative effect on the adjustment range for
camber and caster which can result in greater differences in the toe-out on turns between left and right.

STANDARD PROCEDURE - CHECKING REAR AXLE CAMBER

1. Check the vehicle level at the front and rear axles and adjust if necessary. (Refer to 2 - SUSPENSION/WHEEL

ALIGNMENT - STANDARD PROCEDURE).

2. Check the vehicle level at the front and rear axles with an electronic inclinometer and adjust if necessary. (Refer

to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).
