PROPELLER SHAFT

Drive Condition
Propeller Shaft Noise
Universal Joint Noise
PROPELLER SHAFT BALANCE
NOTE: Removing and indexing the propeller shaft
180° relative to the yoke may eliminate some vibra-
tions.
If propeller shaft is suspected of being out of bal-
ance, verify with the following procedure:
(1) Place vehicle in netrual.
(2) Raise and support the vehicle by the axles as
level as possible.
(3) Clean all foreign material from propeller shaft
and universal joints.
(4) Inspect propeller shaft for missing balance
weights, broken welds, and bent areas.
NOTE: If propeller shaft is bent, it must be replaced.
(5) Inspect universal joints for wear, properly
installed and correct alignment with the shaft.
(6) Check universal joint clamp screws torque.
(7) Remove wheels and tires. Install wheel lug
nuts to retain the brake drums/rotors.
DRIVELINE VIBRATION
Possible Cause
1) Undercoating or other foreign
material on shaft.
2) Loose U-joint clamp screws.
3) Loose or bent U-joint yoke or
excessive runout.
4) Incorrect driveline angularity.
5) Rear spring center bolt not in
seat.
6) Worn U-joint bearings.
7) Propeller shaft damaged or out
of balance.
8) Broken rear spring.
9) Excessive runout or unbalanced
condition.
10) Excessive drive pinion gear
shaft runout.
11) Excessive axle yoke deflection.
12) Excessive transfer case
runout.
1) Loose U-joint clamp screws.
2) Lack of lubrication.
(8) Mark and number propeller shaft six inches
from the pinion yoke end at four positions 90° apart.
(9) Run and accelerate the vehicle until vibration
occurs. Note intensity and speed the vibration
occurred. Stop the engine.
(10) Install a screw clamp at position 1 (Fig. 1).
Correction
1) Clean exterior of shaft and wash
with solvent.
2) Install new clamps and screws
and tighten to proper torque.
3) Install new yoke.
4) Measure and correct driveline
angles.
5) Loosen spring u-bolts and seat
center bolt.
6) Install new U-joint.
7) Installl new propeller shaft.
8) Install new rear spring.
9) Re-index propeller shaft, test,
and evaluate.
10) Re-index propeller shaft and
evaluate.
11) Inspect and replace yoke if
necessary.
12) Inspect and repair as neces-
sary.
1) Install new clamps and screws
and tighten to proper torque.
2) Replace as U-joints as neces-
sary.
