Lincoln Aviator: Driveshaft / General Procedures - Driveshaft Angle Measurement
Check
NOTE:
Prior to checking driveline angularity, inspect the U-joints for correct operation.
NOTE:
An incorrect driveline angle can cause a vibration or shudder.
NOTE:
Driveline angularity is the angular relationship between the
engine crankshaft, the driveshaft and the rear axle pinion. Factors
determining driveline angularity include ride height, rear spring and
engine mounts.
All vehicles
-
Carry out the following preliminary setup steps:
-
Inspect the U-joints for correct operation.
-
Park the vehicle on a level surface such as a drive-on hoist, or back onto a front end alignment rack.
Vehicles with flex coupling, CV joints
-
Calibrate the anglemaster by placing it on the
bottom of the transmission fluid pan and press the ALT-ZERO button.
-
Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402.
-
Measure the slope of the front tube of the rear
driveshaft. The measured angle will be the front joint operating angle.
-
Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402.
-
Calibrate the anglemaster by placing it on the
clean, flat surface of the rear driveshaft front tube and press the
ALT-ZERO button.
-
Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402.
-
Measure the slope of the rear tube of the rear
driveshaft. The measured angle will be the center joint operating angle.
-
Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402.
-
Calibrate the anglemaster by placing it on the
clean, flat locator surface on the right side of the drive axle and
press the ALT-ZERO button.
-
Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402.
-
Measure the slope of the rear tube of the rear
driveshaft. The measured angle will be the rear joint operating angle.
-
Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402.
-
If the angle is not within specifications, repair or
adjust to obtain the correct angle. Inspect the engine mounts,
transmission mounts, transfer case mounts, center support bearing
mounting, rear subframe, rear axle, rear axle mounting or the frame for
wear or damage.
4x4 Vehicles with front driveshafts
-
Front driveshaft joint angle is set from the factory and is not adjustable.
Preliminary Inspection
Visually inspect the CV joints 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...

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.
