Front Steering Knuckle
Description
The steering knuckle is a single casting with legs machined for attachment to the front strut assembly on the top and
steering linkage on the trailing leading end. The steering knuckle also has two machined, drilled legs on the end
casting to support and align the front disc brake caliper adapter.
Operation
The steering knuckle supports the hub and bearing. The front suspension steering knuckle is not a repairable com-
ponent of the front suspension. It must be replaced if damaged in any way. If it is determined that the steering
knuckle is bent when servicing the vehicle, no attempt should be made to straighten the steering knuckle.
Removal & Installation
NOTE :
The following special tools are required to perform the repair procedure:
•CH-10002 - Ball Joint Separator
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly. (Tighten: Wheel mounting nuts to 110 N·m)
3. Use a suitable tool and un-stake the front axle shaft hub nut (1) from the groove in the front axle
shaft.

knuckle.
(Tighten: Strut to the knuckle nuts to 135 N·m)
NOTE :
Do not allow the half shaft to hang by the inner C/V joint. It must be supported to keep the joint from separating
during this operation.
12. Pull the knuckle off the half shaft outer C/V joint splines and remove the knuckle from the vehicle.
13. If required, remove the screws fastening the shield to the knuckle.
14. If required, use a suitable tool to press the hub and bearing out of the knuckle.
15. Installation is in the reverse order of removal.
Installation Notes:
• After installing the front steering knuckle, perform a front end alignment (See Front Wheel Alignment in Section
10 Suspension).
Front Lower Control Arm
Description
The lower control arm is located between the steering knuckle and the vehicle sub-frame. The lower control arm uses
a lower ball joint on the outer end and two sub-frame mounts on the inner end.
Operation
The front lower control arm supports the steering knuckle. The lower control arm controls the vehicle steering by
maintaining the proper wheel alignment through all driving conditions.
Removal & Installation
NOTE :
Inspect the lower control arm for signs of damage from contact with the ground or road debris. If the lower control
arm shows any sign of damage, look for distortion. Do not attempt to repair or straighten a broken or bent lower
control arm. If damaged, the lower control arm is serviced only as a complete component.

Description
A MacPherson type strut assembly is used in place of the traditional front suspension upper control arm and upper
ball joint. The bottom of the strut mounts directly to the steering knuckle using two attaching bolts and nuts going
through the strut clevis bracket and steering knuckle. The top of the strut mounts directly to the strut tower of the
vehicle using the three threaded studs on the strut assembly’s upper mount.

Downloaded from www.Manualslib.com manuals search engine Operation
The strut assembly cushions the ride of the vehicle, controlling vibration, jounce and rebound of the suspension. The
coil spring controls ride quality and maintains proper ride height. The spring isolators isolate the coil spring at the top
and bottom from coming into metal-to-metal contact with the upper mounting seat and the strut. The strut dampens
jounce and rebound motions of the coil spring and suspension.
Diagnosis & Testing
Before removing the front strut, perform the following to test the front strut functionality:
•Adjust the tire pressure to all tires to proper specifications.
• Push and shake the front of the vehicle three or four times with identical force every time
• During the pushing and recoiling, the resistance and recoil times of the vehicle should be equal.
• If the strut (shock absorber) functions properly, the vehicle will recoil several times and then stop recoiling after
the pushing force is removed.
Removal & Installation
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly.
(Tighten: Wheel mounting nuts to 110 N·m)
3. Disconnect the brake fluid hose clamp (1) from the brake fluid hose bracket on the front strut.
4. Remove the brake fluid hose from the bracket.
5. Remove the wheel speed sensor wire.
6. Remove the nut (1) from the front stabilizer bar link bracket on the front strut.
(Tighten: Front stabilizer bar link bracket nut to
