DIAGNOSIS AND TESTING
PROPELLER SHAFT
PROPELLER SHAFT VIBRATION
Out-of-round tires or wheels that are out of balance, will cause a low frequency vibration.
Driveline vibration can also caused by loose or damaged engine mounts.
Propeller shaft vibration increases with vehicle speed. A vibration that occurs at a specific speed range, is not usu-
ally caused by an out of balance propeller shaft. Defective universal joints or an incorrect propeller shaft angle are
usually the cause of such a vibration.

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
If propeller shaft is suspected of being out of balance,
use the following procedure.
NOTE: Indexing propeller shaft 180° relative to the
yoke may eliminate some vibrations.
1. Raise and support vehicle.
2. Clean all foreign material from the propeller shaft
and universal joints.
3. Inspect propeller shaft for missing balance weights,
broken welds and bent areas. If propeller shaft is
bent, it must be replaced.
4. Inspect universal joints for wear and properly
installed.
5. Check propeller shaft bolt torques.
6. Remove wheels and install lug nuts to retain brake
rotors.
7. Mark and number the shaft six inches from the pin-
ion yoke end at four positions 90° apart.
8. Run and accelerate vehicle until vibration occurs. Note the intensity and speed the vibration occurred. Stop the
engine.
