Lincoln Corsair: Front Drive Halfshafts / Diagnosis and Testing - Front 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.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).

Pinpoint Tests
PINPOINT TEST A: AXLE HOWLING OR WHINE – FRONT OR REAR AXLE
Normal Operation and Fault Conditions
Halfshafts transmit rotary motion through constant velocity joints in a uniform manner. The outer CV
joints use balls, have no length compensation and engage in the wheel
hubs. The intermediate shaft (right side) is correctly positioned and
secured in the differential by the intermediate shaft center bearing.
The left CV joint is locked in the differential by a snap-ring.
Possible Sources
- Damaged or worn wheel hub bearings
|
A1 INSPECT WHEEL HUB BEARINGS |
-
Inspect wheel hub bearings
Was any wheel hub bearing play or damage found?
Yes |
Install a new wheel hub bearing. REFER to: Front Wheel Bearing and Wheel Hub (204-01 Front Suspension, Removal and Installation).
|
No |
Inspect the vehicle for any other symptoms related to the halfshafts.

Vehicle Loading - with and without a Trailer
This section guides you in the proper
loading of your vehicle, trailer, or both.
Keep your loaded vehicle weight within
its design rating capability, with or
without a trailer. Properly loading your
vehicle provides maximum return of
vehicle design performance...
WARNING: Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel can
affect the safety and performance of your
vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure...
