HALF SHAFT KIT:
| Quantity | Part Name |
|---|---|
| 1 | LH Half Shaft (M-4139-M) |
| 1 | RH Half Shaft (M-4138-M) |
NOTICE: Suspension fasteners are critical parts that affect the
performance of vital components and systems. Failure of these fasteners may
result in major service expense.
Use the same or equivalent parts if replacement is necessary. Do not use a
replacement part of lesser quality or substitute design. Tighten fasteners as
specified.
NOTICE: Any fasteners with damage or corrosion must be replaced
INSTALLATION INSTRUCTIONS:
STEP 1: Raise and support vehicle to gain access to underside.
STEP 2:
Remove the wheel nuts from both rear wheels.
STEP 3:
Remove and discard the spindle nut.
STEP 4: Using
Special Service Tool: 205-D070 (D93P-1175-B) or equivalent, Press the
halfshaft breaking the splines free from the hub.
STEP 5: Remove the 2 bolts and position the brake caliper and anchor
plate assembly aside. Clean and remove any thread locking compound from the
bolts.
NOTE: Do not allow the brake caliper and anchor plate assembly to hang
from the brake hose or damage to the hose may occur. STEP 6: Remove the
brake disc.
STEP 7: Remove the wheel speed sensor bolt (1) and position aside the
wheel speed sensor. Remove the parking brake cable bracket bolt (2) and
position the parking brake cable bracket aside. 
STEP 8: Support the suspension at curb height. Use
General Equipment: Vehicle/Axle Stands
STEP 9:
Remove the 2 lower arm vertical link bolts and remove the lower arm vertical
link. Clean and remove any thread locking compound from the bolts.
STEP 10: Remove the wheel knuckle-to-upper arm
bolt and nut (1).Remove the wheel knuckle-to-toe link bolt and nut (2). Remove
the wheel knuckle-to-lower arm bolt (3). Remove the knuckle / hub assembly. A
light tap from a dead blow hammer may be required to assist the halfshaft
removal from the hub. Clean and remove any thread locking compound from the
bolts
NOTE: Support the halfshaft when removing the knuckle / hub assembly.
NOTE: Hub is removed from the image for clarity.
Rear Halfshaft Notes:
NOTICE: Never pick up or hold the halfshaft by only the inner or outer
Constant Velocity (CV) joint. Damage to the CV joint will occur.
NOTICE: Never use a hammer to remove or install the halfshafts. Damage to
the CV joint may occur.
NOTICE: Never use the halfshaft assembly as a lever to position other
components. Damage to the halfshaft or CV joint may occur.
NOTICE: Do not allow the boots to contact sharp edges or hot exhaust
components. Damage to the halfshaft boots will occur.
NOTICE: Do not drop assembled halfshafts. The impact may cut the boots
from the inside without evidence of external damage.
STEP 11: Be sure to clean area around halfshaft of any dirt and debris
prior to removal of the halfshaft to prevent any debris from contaminating
parts. Then, using a pry bar, remove the halfshaft.
Inspect the old inner spline for the retainer clips. (If not on spline, locate
within differential)
STEP 12:
Inspect the new halfshafts and verify the halfshaft retainer clips are in
place.
STEP 13: Install the halfshaft
until the halfshaft circlip is fully seated.
NOTE: After insertion, pull the halfshaft inner end to make sure the
circlip is locked.When seated correctly, the halfshaft retainer circlip can be
felt as it snaps into the differential side gear groove.
NOTICE: Tighten the
following suspension bushing fasteners with the suspension loaded or with the
weight of the vehicle resting on the wheels and tires, otherwise incorrect
clamp load and bushing damage may occur.
STEP 14 : Place a small amount of anti-seize onto the outer halfshaft
splines. Position the wheel knuckle / hub assembly, guide the halfshaft into
the hub and install the wheel knuckle-to-lower arm bolt (1) with BLUE thread
locking compound. Torque to: 203 lb.ft (275 Nm). Install the wheel knuckle-
totoe link bolt and nut (2) with BLUE thread locking compound. Torque to: 129
lb.ft (175 Nm). Install the wheel knuckle-to-upper arm bolt and nut (3) with
BLUE thread locking compound.
Torque to: 76 lb.ft (103 Nm).
NOTE: Hub is
removed from the image for clarity.
STEP 15: Position the parking brake cable bracket and install the parking
brake cable bracket bolt with BLUE thread locking compound. Torque to: 21
lb.ft (28 Nm). Position the wheel speed sensor and install the wheel speed
sensor bolt with BLUE thread locking compound. Torque to : 80 lb.in (9
Nm)
STEP 16: Position the lower
arm vertical link and install the 2 lower arm vertical link bolts with BLUE
threadlocking compound. Tighten the lower arm vertical link upper bolt. Torque
to: 76 lb.ft (103 Nm)
Tighten the lower arm vertical link lower bolt. Torque to: 129 lb.ft (175 Nm)
STEP 17: Install the rear
rotors onto the rear hubs. STEP 18: Install the brake
caliper and anchor plate assembly using 2 bolts with BLUE thread locking
compound. Torque to: 129 lb.ft (175 Nm)
STEP 19 : Install the new spindle nuts with Blue thread locking compound.
Torque Stage 1: 98 lb.ft (133 Nm). Torque Stage 2: 45°
STEP 20: Remove the differential fluid fill plug.
STEP 21: Check and top off
the differential with clean differential gear lubricant. The differential gear
lubricant level should be within 9mm (0.354 in.) from the fluid level fill
plug opening.
Recommended fluid: Motorcraft® SAE 75W-85 Premium Synthetic Hypoid Gear
Lubricant / XY75W85-QL
STEP 22:
Install the differential fluid fill plug. Torque to: 25 lb.ft (34 Nm)
WARNING: When a wheel is installed, always remove any corrosion, dirt or
foreign material present on the mounting surface of the wheel and the mounting
surface of the wheel hub, brake drum or brake disc. Make sure that any
fasteners that attach the rotor to the hub are secured so they do not
interfere with the mounting surfaces of the wheel. Failure to follow these
instructions when installing wheels may result in the wheel nuts loosening and
the wheel coming off while the vehicle is in motion, which could result in
loss of control,leading to serious injury or death to vehicle occupant(s).
NOTE: Make sure to apply a thin coat of anti-seize lubricant only to the
interface between the wheel pilot bore and the hub pilot. Do not allow the
anti-seize to make contact with the wheel-to-brake disc/drum mounting surface,
wheel studs, wheel nuts, brake pads or brake disc friction surfaces or damage
to components may occur.
WARNING: Retighten wheel nuts within 160 km (100 mi) after a wheel is
reinstalled. Wheels can loosen after initial tightening. Failure to follow
this instruction may result in serious injury to vehicle occupant(s).
NOTE: Failure to tighten the wheel nuts in a star/cross pattern can
result in high brake disc runout, which accelerates the development of brake
roughness, shudder and vibration.
NOTE: The wheel nut torque specification is for clean, dry wheel stud and
wheel nut threads.
NOTE: Final tightening to be performed with vehicle resting on tires.
STEP 23: Clean the mounting surface of the wheel. Apply the substance
from the specified tube.
Material: High Temperature Nickel Anti-Seize Lubricant / XL-2
STEP 24:
Position the wheel and install the wheel nuts. Tighten the wheel nuts in a
star pattern.
Torque to: 148 lb.ft (200 Nm)
