PROPELLER SHAFT
DIAGNOSIS AND TESTING
PROPELLER SHAFT VIBRATION
Tires that are out-of-round or wheels that are
unbalanced, will cause a low frequency vibration.
Brake drums that are unbalanced will cause a
harsh, low frequency vibration.Driveline vibration can also result from loose or
damaged engine mounts.
Propeller shaft vibration increases as the vehicle
speed is increased. A vibration that occurs within a
specific speed range is not usually caused by a pro-
peller shaft being unbalanced. Defective universal
joints or an incorrect propeller shaft angle are usu-
ally the cause of such a vibration.
DRDIFFERENTIAL & DRIVELINE 3 - 1

DRIVELINE VIBRATION
Drive Condition Possible Cause Correction
Propeller Shaft Noise 1) Undercoating or other foreign
material on shaft.1) Clean exterior of shaft and wash
with solvent.
2) Loose U-joint clamp screws. 2) Install new clamps and screws
and tighten to proper torque.
3) Loose or bent U-joint yoke or
excessive runout.3) Install new yoke.
4) Incorrect driveline angularity. 4) Measure and correct driveline
angles.
5) Rear spring center bolt not in
seat.5) Loosen spring u-bolts and seat
center bolt.
6) Worn U-joint bearings. 6) Install new U-joint.
7) Propeller shaft damaged or out
of balance.7) Installl new propeller shaft.
8) Broken rear spring. 8) Install new rear spring.
9) Excessive runout or unbalanced
condition.9) Re-index propeller shaft, test,
and evaluate.
10) Excessive drive pinion gear
shaft runout.10) Re-index propeller shaft and
evaluate.
11) Excessive axle yoke deflection. 11) Inspect and replace yoke if
necessary.
12) Excessive transfer case runout. 12) Inspect and repair as necessary.
Universal Joint Noise 1) Loose U-joint clamp screws. 1) Install new clamps and screws
and tighten to proper torque.
2) Lack of lubrication. 2) Replace as U-joints as
necessary.
PROPELLER SHAFT BALANCE
NOTE: Removing and re-indexing the propeller
shaft 180É relative to the yoke may eliminate some
vibrations.
If propeller shaft is suspected of being unbalanced,
it can be verified with the following procedure:
(1) Raise the vehicle.
(2) Clean all the foreign material from the propel-
ler shaft and the universal joints.
(3) Inspect the propeller shaft for missing balance
weights, broken welds, and bent areas.If the pro-
peller shaft is bent, it must be replaced.
(4) Inspect the universal joints to ensure that they
are not worn, are properly installed, and are cor-
rectly aligned with the shaft.
(5) Check the universal joint clamp screws torque.
(6) Remove the wheels and tires. Install the wheel
lug nuts to retain the brake drums or rotors.
(7) Mark and number the shaft six inches from the
yoke end at four positions 90É apart.(8) Run and accelerate the vehicle until vibration
occurs. Note the intensity and speed the vibration
occurred. Stop the engine.
(9) Install a screw clamp at position 1 (Fig. 1).
(10) Start the engine and re-check for vibration. If
there is little or no change in vibration, move the
clamp to one of the other three positions. Repeat the
vibration test.
(11) If there is no difference in vibration at the
other positions, the source of the vibration may not
be propeller shaft.
(12) If the vibration decreased, install a second
clamp (Fig. 2) and repeat the test.
(13) If the additional clamp causes an additional
vibration, separate the clamps (1/2 inch above and
below the mark). Repeat the vibration test (Fig. 3).
(14) Increase distance between the clamp screws
and repeat the test until the amount of vibration is
at the lowest level. Bend the slack end of the clamps
so the screws will not loosen.

(15) If the vibration remains unacceptable, apply
the same steps to the front end of the propeller shaft.
(16) Install the wheel and tires. Lower the vehicle.
PROPELLER SHAFT RUNOUT
(1) Remove dirt, rust, paint and undercoating from
the propeller shaft surface where the dial indicator
will contact the shaft.
(2) The dial indicator must be installed perpendic-
ular to the shaft surface.
(3) Measure runout at the center and ends of the
shaft sufficiently far away from weld areas to ensure
that the effects of the weld process will not enter into
the measurements.
(4) Refer to Runout Specifications chart.
(5) If the propeller shaft runout is out of specifica-
tion, remove the propeller shaft, index the shaft 180É,
and re-install the propeller shaft. Measure shaft
runout again.
(6) If the propeller shaft runout is now within
specifications, mark the shaft and yokes for proper
orientation.
(7) If the propeller shaft runout is not within spec-
ifications, verify that the runout of the transmission/
transfer case and axle are within specifications.
Correct as necessary and re-measure propeller shaft
runout.
(8) Replace the propeller shaft if the runout still
exceeds the limits.
RUNOUT SPECIFICATIONS
Front of Shaft 0.020 in. (0.50 mm)
Center of Shaft 0.025 in. (0.63 mm)
Rear of Shaft 0.020 in. (0.50 mm)
note:
Measure front/rear runout approximately 3 inches (76
mm) from the weld seam at each end of the shaft
tube for tube lengths over 30 inches. For tube lengths
under 30 inches, the maximum allowed runout is
0.020 in. (0.50 mm) for the full length of the tube.
STANDARD PROCEDURE
PROPELLER SHAFT ANGLE
This procedure applies to both the front/rear pro-
peller shafts. To obtain the front output angle (A) on
the front propeller shaft, place the inclinometer the
machined surface of the C/V joint.
(1) To check driveline alignment, raise and support
the vehicle at the axles as level as possible. Allow the
wheels and propeller shaft to turn.
(2) Remove any external bearing snap rings, if
equipped from universal joint so protractor base sits
flat.

CAUTION
CAUTION:: Never grasp half shaft assembly by the
boots. This may cause the boot to pucker or crease
and reduce the service life of the boot.
Avoid over angulating or stroking the C/V joints
when handling the half shaft.
Half shafts exposed to battery acid, transmission
fluid, brake fluid, differential fluid or gasoline may
cause the boots to deteriorate.
DIAGNOSIS AND TESTING
Check for grease at the inboard and outboard C/V
joint. This is a sign of boot or boot clamp damage.
NOISE/VIBRATION IN TURNS
A clicking noise or a vibration in turns could be
caused by a damaged outer C/V or inner tripod joint
seal boot or seal boot clamps. This will result in the
loss/contamination of the joint grease, resulting in
inadequate lubrication of the joint. Noise could also
be caused by another component of the vehicle com-
ing in contact with the half shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of a damaged or worn
C/V joint. A torn boot or loose/missing clamp on the
inner/outer joint which has allowed the grease to be
lost will damage the C/V joint.
SHUDDER/VIBRATION DURING ACCELERATION
This problem could be a result of a worn/damaged
inner tripod joint or a sticking tripod joint. Improper
wheel alignment may also cause a shudder or vibra-
tion.
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of out of balance
front tires or tire/wheel runout. Foreign material
(mud, etc.) packed on the backside of the wheel(s)
will also cause a vibration.
REMOVAL
(1) Loosen lug nuts and hub nut while the with
the vehicle brakes applied.
(2) Raise and support the vehicle.
(3) Remove wheel and tire assembly
