Lincoln Aviator: Rear Drive Halfshafts / Diagnosis and Testing - Rear Drive Halfshafts
Preliminary Inspection
-
Visually inspect the CV joints, housing, boots, and clamps for obvious signs of mechanical damage.
-
If an obvious cause for an observed or reported concern is
found, correct the cause (if possible) before proceeding to the next
step
-
If the cause is not visually evident, verify the symptom and REFER to Symptom Chart: NVH.
Symptom Chart(s)
Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.

Actions
|
Driveline clunk - loud clunk when shifting from REVERSE to DRIVE
|
-
Damaged or worn Constant Velocity (CV) joints
|
-
INSPECT the Constant Velocity
(CV) joints for wear or damage. INSTALL a new halfshaft as necessary.
REFER to: Rear Halfshaft (205-05 Rear Drive Halfshafts, Removal and Installation).
|
|
-
CHECK the torque on the hub nut.
REPLACE the hub nut if the torque is not at specification. For hub
nuts.
REFER to: Wheel Bearing and Wheel Hub (204-02 Rear Suspension, Removal and Installation).
|
Driveline clunk — occurs as the vehicle starts to move forward following a stop
|
|
-
CHECK the torque on the hub nut.
REPLACE the hub nut if the torque is not at specification.
REFER to: Rear Halfshaft (205-05 Rear Drive Halfshafts, Removal and Installation).
REFER to: Wheel Bearing and Wheel Hub (204-02 Rear Suspension, Removal and Installation).
|
Grunting — normally associated with a
shudder experienced during acceleration from a complete stop
|
-
Halfshaft Constant Velocity (CV) joint binding
|
-
CHECK the outer Constant
Velocity (CV) joint for correct seating into the hub. REPAIR as
necessary.
REFER to: Rear Halfshaft (205-05 Rear Drive Halfshafts, Removal and Installation).
|
Driveline vibration - occurs at cruising speeds
|
-
Binding or damaged Constant Velocity CV joint
|
-
CHECK the outer CV joint for correct seating into the hub. REPAIR as necessary.

Differential Seals
NOTICE:
When installing shafts, do not allow splines to contact seals during installation or damage to the seals may occur.
Halfshaft
seals are susceptible to the same types of damage as drive pinion seals
if incorrectly installed. The seal bore must be clean and the lip
handled carefully to avoid cutting or tearing it. The seal journal
surface must be free of nicks, gouges and rough surface texture.
For information on differential seals,
REFER to: Rear Halfshaft Seal (205-02 Rear Drive Axle/Differential, Removal and Installation).
Removal
NOTICE:
Never pick up or hold the halfshaft by only the inner or outer CV joint. Damage to the CV joint will occur.
NOTICE:
Never use a hammer to remove or install the halfshafts...

Tire Pressure Monitor (TPMS)
Activation
NOTE:
The tire pressure sensors will go into a "sleep
mode" when a vehicle is stationary to conserve battery power. The
sensors do not transmit information while in sleep mode...
Categories
The front outboard and rear safety restraints
in the vehicle are combination lap and
shoulder belts.
Insert the belt tongue into the proper
buckle (the buckle closest to the direction
the tongue is coming from) until you hear
a snap and feel it latch. Make sure that
you securely fasten the tongue in the
buckle.

To unfasten, press the release button
and remove the tongue from the buckle.
