CHRY - Steering Columns - Trucks & Vans
Caravan, Dakota, Durango, Ram Pickup, Ram Van/Wagon,
Town & Country, Voyager
WARNING: All models are equipped with Air Bag Restraint System (ABRS).
See AIR BAG PRECAUTIONS before working on vehicle. Use
caution when working around steering column (air bag could
deploy).
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
DESCRIPTION & OPERATION
All models use collapsible steering columns with an integral
ignition switch and locking device. See Fig. 1. Optional tilt wheel is
available.
AIR BAG PRECAUTIONS
Follow precautions when working with air bag systems:
* When performing air bag repairs, disable ABRS. See AIR BAG
DISABLING.
* Use caution when handling a sensor. Never strike or jar a
sensor. All sensors or mounting bracket bolts must be
carefully torqued to ensure proper sensor operation.
* Never apply power to ABRS if a sensor is not rigidly attached
to vehicle.
* To avoid accidental air bag deployment while trouble shooting
ABRS, DO NOT use electrical test equipment, such as AC
-powered or battery-powered voltmeter, ohmmeter, etc.
* Always carry air bag module with trim cover away from body.
Always place inflatable module on workbench with trim cover
up, away from loose objects.
* DO NOT install used air bag parts from another vehicle. Use
NEW parts only. DO NOT disassemble or tamper with air bag
assembly.
* Wait at least 2 minutes after disconnecting battery before
proceeding with repairs or trouble shooting system. For a
short time after battery is disconnected, ABRS retains enough
voltage to deploy air bag.
NOTE: For additional information, see appropriate AIR BAG RESTRAINT
SYSTEMS article in ACCESSORIES & EQUIPMENT section.
AIR BAG DISABLING
Disconnect and isolate negative battery cable. Disconnect 2-
way yellow clockspring harness connector, located on top of fuse block
between clockspring and instrument panel wiring harness. Clockspring
connector may also be disconnected at Air Bag System Diagnostic Module
(ASDM).

clockspring connector. Connect negative battery cable. On column shift
models, install NEW shift lever bushing using pliers and back-up
washer to snap bushing into place. Use a multipurpose grease to aid
installation.
6) Connect gearshift cable rod to shift lever by snapping rod
into bushing with pliers.

1998-99 DRIVE AXLES
CHRY - 4WD Steering Knuckles
Ram Pickup
DESCRIPTION
Open type steering knuckles are used on all models. Open type
knuckles provide sharper turning angle, decreasing turning radius.
Axle shafts are free floating. Steering knuckles are attached to axle
housing by ball joints.
REMOVAL & INSTALLATION
REMOVAL
1) Raise and support vehicle. Remove wheels. Remove brake
caliper, and support aside. DO NOT allow caliper to hang by brake
hose. On one ton models, remove adapter hub bolts and hub from rotor
and hub assembly. On all models, remove cotter pin from rotor and hub
nut.
2) Remove rotor and hub nut. Remove bolts securing rotor and
hub assembly to steering knuckle. Bolts are accessible from inboard
side of steering knuckle. Remove rotor and hub assembly. Remove hub
spacer from steering knuckle. Note spacer position for installation
reference.
3) Disconnect tie rod end and drag link studs. Remove anti-
lock brake sensor from steering knuckle. Remove ball joint cotter pins
and nuts. Discard lower nut. Using a soft-face hammer, tap steering
knuckle to free it from ball joints.
4) Clean all components with solvent, and dry with compressed
air. Inspect all parts for burrs, chips, wear, flat spots or cracks.
Replace all damaged or worn parts.
INSTALLATION
NOTE: When aligning upper ball joint nut to install cotter pin,
always tighten nut to align holes. Never loosen nut to align
holes.
1) Position steering knuckle on ball joints, and install NEW
lower ball joint nut. Tighten nut to specification. See TORQUE
SPECIFICATIONS. Install upper ball joint nut, and tighten to
specification. Tighten, DO NOT loosen, nut to install NEW cotter pin.
2) Install hub bearing and axle shaft. Connect drag link stud
to steering knuckle arm. Install retaining nut, and tighten to
specification. Install NEW cotter pin. Connect tie rod end stud to
steering knuckle arm. Install retaining nut and tighten to
specification. Install NEW cotter pin. Install anti-lock brake sensor
to steering knuckle.
3) Apply anti-seize compound to splines of front drive axle.
Inspect hub grease seal and wheel bearing. Replace as necessary. From
rear of steering knuckle, install 2 rearward rotor and hub assembly
bolts in steering knuckle.
4) Apply chassis grease to hub spacer to secure on steering
knuckle. Position spacer on rotor and hub assembly bolts. Ensure
spacer is installed with flat edge toward rear of vehicle. Apply
Loctite to rotor and hub assembly bolt threads. Install rotor and hub
