Removal Procedure
Important: Observe and accurately reference mark the positions of all driveline components
relative to the propeller shaft prior to disassembly. These components include the
propeller shafts, drive axles, pinion flange, inner axle shafts, etc. Reassemble
all components in the exact relationship the components had to one another prior
to disassembly. Follow the specifications, torque values and any measurement made
prior to disassembly in order to maintain the factory system balance of the driveline
components. System balance provides a smoother running driveline operation.
- Unlock the steering column allowing the steering linkage to move freely.
- Raise the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Strap the frame to the hoist in order to
prevent movement.
- Remove the tire and wheel assembly. Refer to
Wheel Removal
in Tires and Wheels.
- Insert a drift through the brake caliper
and into a brake rotor vane to prevent the wheel drive shafts from turning.
- Remove the axle nut and the washer.
Discard the nut.
- Remove the drift from the brake rotor.
- Remove the brake hose bracket from the upper
control arm.
- Remove the wheel sensor wire bracket from
the upper control arm.
- Remove the brake caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
Support the caliper with a piece of wire in order to prevent damage to the brake
hose.
- Remove the brake rotor.
- Remove the shock absorber bottom mounting
nut and the bolt.
Compress the shock absorber.
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 the safety stand.
- Disconnect the wheel drive shaft from the
steering knuckle by placing a brass drift on the end of the shaft and striking the
drift with a hammer.
Do not attempt to remove the wheel drive shaft at this time.
- Disconnect the upper control arm ball joint from the steering knuckle.
Refer to
Upper Control Arm Ball Joint Replacement
in Front
Suspension.
- Disconnect the lower control arm ball joint from the steering knuckle.
Refer to
Lower Control Arm Ball Joint Replacement
in Front
Suspension.
After the lower control arm ball joint is loose from the knuckle, simultaneously
push the wheel drive shaft toward the differential carrier in order to allow room
to remove the steering knuckle.
- Remove the steering knuckle from the wheel drive shaft.
Support the knuckle with a piece of wire from the upper control arm in order
to prevent any strain on the outer tie rod and the wheel speed sensor wire.
- Lower the safety stand with the lower control arm enough to allow clearance
to remove the wheel drive shaft.
Important: Do not damage the differential carrier axle seals during wheel drive shaft removal.
- In order to prevent damage to the drive axle CV joint boots, cover the following
components with a shop towel:
• | The shock mounting bracket |
• | The lower control arm ball stud |
- Disconnect the wheel drive shaft from the
front differential carrier by placing a brass drift or block of wood on the tripot
housing and striking the drift with a hammer. Strike hard enough to overcome the snap
ring pressure holding the drive axle to the differential carrier.
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 wheel drive shaft from the vehicle.
- Inspect the seal on the steering knuckle for damage. Check the seal for
any cuts or tears. Lubricate the seal lip. If the seal is cut or torn, then check
the wheel bearing for damage and replace the seal. Refer to
Front Wheel Hub, Bearing, and Seal Replacement
.
Installation Procedure
Important: Reassemble all components in the exact relationship the components had to one
another prior to disassembly. Follow the specifications, torque values and any measurement
made prior to disassembly in order to maintain the factory system balance of the
driveline components. System balance provides a smoother running driveline operation.
Important: Do not lubricate or damage the differential carrier axle seals during installation.
- In order to prevent damage to the drive axle CV joint boots, 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 by doing the
following:
2.1. | Using both hands, align the splines on the shaft with the differential
housing. |
2.2. | Center the wheel drive shaft into the differential carrier. |
2.3. | Firmly push the shaft straight into the differential carrier until the
retaining rings sits in the differential carrier. |
- Pull back on the tripot housing to ensure
that the retaining ring is properly retaining the drive axle in the differential
carrier. You should not be able to pull the wheel drive shaft out of the differential
carrier when the retaining ring is properly seated.
- Remove shop towels covering the following components.
• | The shock mounting bracket |
• | The lower control arm ball stud |
- Guide the drive axle into the steering knuckle.
Notice: Be careful that the safety stand does not damage or bend
any components it may contact.
- Raise the lower control arm with the safety stand to insert the
lower control arm ball stud into the steering knuckle.
- Assemble the lower ball joint. Refer to
Lower Control Arm Ball Joint Replacement
in Front Suspension.
- Install the upper control arm ball joint to the steering knuckle. Refer
to
Upper Control Arm Ball Joint Replacement
in Front Suspension.
- Install the shock absorber to the lower mount.
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 bolt and the nut.
Tighten
Tighten the bolt to 62 N·m (46 lb ft).
- Install the brake rotor.
- Install the brake caliper. Refer to
Brake Caliper Replacement
in Disc Brakes.
- Install the wheel speed sensor bracket to
the upper control arm.
Tighten
Tighten the wheel speed sensor bracket nut to 16 N·m (12 lb ft).
- Install the brake hose bracket to the upper
control arm.
Tighten
Tighten the brake hose bracket nut to 16 N·m (12 lb ft).
- Insert a drift through the brake caliper
and into a brake rotor vane to prevent the wheel drive shaft from turning.
- Install the wheel drive shaft washer and
the new nut.
Tighten
Tighten the axle nut to 200 N·m (147 lb ft).
- Install the tire and the wheel. Refer to
Wheel Installation
in Tires and Wheels.
- Check the front axle fluid level and add if needed. Use the proper fluid.
Refer to
Sealers, Adhesives, and Lubricants
in Front
