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.
- Remove the tire and wheel assembly. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Insert a drift through
the brake caliper and into a brake rotor vane to prevent the wheel drive shaft
from turning.
- Remove the wheel drive shaft nut.
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.
- 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.
- Remove the steering knuckle. Refer to
Steering Knuckle Replacement
in Front Suspension.
It is not necessary to remove the wheel hub assembly from the steering
knuckle.
Important: Do not damage the differential carrier assembly 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 assembly 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 assembly.
- Remove the wheel drive shaft.
Installation Procedure
Important: Do not lubricate or damage the differential carrier assembly 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 into the differential carrier assembly
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 assembly. |
2.3. | Firmly push the shaft straight into the differential carrier assembly
until the retaining rings sits in the differential carrier assembly. |
- Pull back on the tripot
housing to ensure that the retaining ring is properly retaining the wheel
drive shaft in the differential carrier assembly. You should not be able
to pull the wheel drive shaft out of the differential carrier assembly
when the retaining ring is properly seated.
- Remove the shop towels.
- Install the steering knuckle. Refer to
Steering Knuckle Replacement
in Front Suspension.
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
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 new wheel drive shaft nut.
Tighten
Tighten the axle nut to 200 N·m (147 lb ft).
- Install the tire and the wheel. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Check the front axle fluid level and add, if necessary. Use the
proper fluid. Refer to
Lubricant Level Check
.
- Lower the vehicle.
