Removal Procedure
- Unlock the steering column so that the steering linkage is free
to move.
- Raise the vehicle. Support
the vehicle with suitable safety stands. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the front tires and wheels. Refer to
Tire and Wheel Removal and Installation
in Tires
and Wheels.
- In order to prevent the
drive axle from turning, insert a drift through the brake caliper and into
one of the rotor vanes.
- Remove the axle nut and
washer.
- Remove the drift from the brake rotor. Support the caliper with
a piece of wire in order to prevent damage to the brake hose.
- Remove the caliper. Refer to
Front Brake Caliper Replacement
in Disc Brakes.
- Remove the rotor. Refer to
Front Brake Rotor Replacement
in Disc Brakes.
- Remove the brackets from
the upper control arm holding both the ABS wire and the brake hose.
- Remove the ABS bracket located on the top of the upper control
arm ball joint.
- Strap the frame to the
hoist in order to prevent movement.
Notice: Be careful that the safety stand does not damage or bend
any components it may contact.
- Position a safety stand under the lower control arm.
- Support the weight of the steering knuckle assembly and lower
control arm with a safety stand.
- Disengage the wheel drive
shaft from the hub by placing a brass drift against the outer end of the drive
axle in order to protect the threads. Sharply strike the brass drift
using a hammer. Do not attempt to remove the axle at this time.
- Support the steering knuckle and assembly with a piece of wire
in order to prevent damage to the outer tie rod and ABS wire.
- Remove the upper ball joint. Refer to
Upper Control Arm Ball Joint Replacement
in Front Suspension.
- Remove the shock absorber from the lower mount only. Refer to
Shock Absorber Replacement
in Front Suspension.
Important: After the lower ball joint is loose from the knuckle, simultaneously
push the axle shaft in toward the differential carrier in order to allow room
for the knuckle and assembly to be removed.
- Remove the lower ball joint. Refer to
Lower Control Arm Ball Joint Replacement
in Front Suspension.
- Remove the axle from the steering knuckle assembly.
Important: Lower the safety stand from the lower control arm in order to relieve
the pressure of the torsion bar and in order to allow for clearance.
Do not damage the axle seal during removal of the differential carrier
shield.
- Remove the front differential carrier shield.
- Disconnect the left side
wheel drive shaft from the differential carrier by placing a block of wood
or a brass drift against the tripot housing. Firmly strike the block
of wood outward from the case with a hammer. Strike hard enough in order
to overcome the snap ring pressure holding in the shaft.
- Disconnect the right side
wheel drive shaft from the differential carrier by placing a block of wood
or a brass drift against the tripot housing. Firmly strike the block
of wood outward from the case with a hammer. Strike hard enough in
order to overcome the snap ring pressure holding in the shaft.
- Pull the axle straight
out from the differential carrier.
- Support the drive axle in order to prevent tearing the boot.
Caution: To prevent personal injury and/or component damage, do not allow the
weight of the vehicle to load the front wheels, or attempt to operate the
vehicle, when the wheel drive shaft(s) or wheel drive shaft nut(s) are removed.
To do so may cause the inner bearing race to separate, resulting in damage
to brake and suspension components and loss of vehicle control.
- Remove the drive axle.
Installation Procedure
Important: Do not lubricate or damage the differential carrier axle seals during
installation.
- In order to prevent damage to the boot, cover the following components
with a shop towel:
• | The shock mounting bracket |
• | The lower control arm ball stud |
- Install the wheel drive
shaft to the differential carrier.
2.1. | With both hands on the tripot housing, align the splines on the
shaft with the differential carrier. |
2.2. | Center the drive axle into the differential carrier seal. |
2.3. | Firmly push the shaft straight into the differential carrier until
the snap ring seats into place. |
Notice: Be careful that the safety stand does not damage or bend
any components it may contact.
- Raise the safety stand to support the weight of the lower control arm.
Important: It will be necessary to slightly start the knuckle onto the drive axle
while simultaneously guiding the lower ball stud to its proper location on
the steering knuckle.
- Assemble the lower ball joint. Refer to
Lower Control Arm Ball Joint Replacement
in Front Suspension.
- Install the lower shock mount. Refer to
Shock Absorber Replacement
in Front Suspension.
- Install the upper ball joint. Refer to
Upper Control Arm Ball Joint Replacement
in Front Suspension.
- Install the drive axle
washer and nut.
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.
- Install the wheel
drive shaft nut.
Tighten
Tighten the nut to 140 N·m (103 lb ft).
- Install the ABS bracket
located on the top of the upper control arm ball joint.
- Install the brackets from the upper control arm holding both the
ABS wire and the brake hose.
- Install the rotor. Refer to
Front Brake Rotor Replacement
in Disc Brakes.
- Install the caliper. Refer to
Front Brake Caliper Replacement
in Disc Brakes.
- Install the tires and wheels. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Remove the safety stands.
- Install the front differential
carrier shield.
- Install the front differential carrier shield bolts.
Tighten
Tighten the bolts to 25 N·m (19 lb ft).
- Remove the strap from the frame.
- Lower the vehicle.
