Important:
• | Raise and support the vehicle on a twin-post hoist in order to
compress the front coil spring and provide accessibility to the wheel and
the steering knuckle assembly. |
• | If a frame hoist is used, support the lower control arm with an
adjustable jackstand in order to safely retain the spring in the curb height
position. |
- Raise the vehicle.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Remove the brake caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
- Remove the hub/rotor. Refer to
Front Wheel Hub, Bearing, and Seal Replacement
.
- Remove the bolts (3) and
the washers (4) of the splash shield.
- Remove the gaskets (5).
- Remove the splash shield (2).
- Disconnect the steering knuckle from the tie rod end. Refer to
Tie Rod Replacement
in Steering Linkage.
Caution: Floor jack must remain under the lower control arm during
removal and installation to retain the lower control arm in position. Failure
to do so could result in personal injury.
- Disconnect the steering knuckle from the upper ball joint. Refer to
Upper Control Arm Replacement
.
- Disconnect the steering
knuckle from the lower ball joint.
10.1. | Use the J 23742
in
order to break the lower ball joint free from the steering knuckle. |
10.2. | Lift the steering knuckle off of the lower ball joint. |
- Inspect the tapered holes in the steering knuckle that attach
to the ball joints and the tie rod end.
• | If any tapered hole is out of round, deformed, or damaged in any
way, replace the steering knuckle. |
- Inspect the spindle for wear or damage. If the spindle is damaged
or worn, replace the steering knuckle.
Installation Procedure
For control arms and components, refer to
Upper Control Arm Replacement
or
Lower Control Arm Replacement
.
- Connect the steering knuckle to the lower ball joint. Press the
steering knuckle onto the lower ball joint until the knuckle is fully seated.
- Connect the steering knuckle to the upper ball joint. Lower the
upper control arm in order to seat the upper ball joint into the steering
knuckle.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.

amount in order to align the cotter pin.
- Remove the floor jack.
- Connect the tie rod end to the steering knuckle. Refer to
Tie Rod Replacement
in Steering Linkage.
- Install the splash shield
(2).
- Install the washers (4) and the bolts (3).
Tighten
