3D-7 Propeller Shafts:
Step
Based on the Vibration Analysis - Road Testing table, is the
8
concern second order driveline related?
Does the vehicle driveline contain any U-joints?
9
Based on the Vibration Analysis - Road Testing table, is the
10 concern a noise that is not felt?
1. Inspect the following components for wear and/or damage:
– Inspect the propeller shafts for dents, damage, missing
weights, and/or undercoating.
– Inspect the U-joint, or joints, if equipped, for excessive
wear, looseness, and/or damage.
– Inspect the prop shaft constant velocity (CV) joint, or
joints, if equipped, for excessive wear, looseness, and/
or damage.
– Inspect the prop shaft coupler assembly, or assemblies,
11
if equipped, for excessive wear, looseness, and/or
damage.
– Inspect the prop shaft support bearing, if equipped, for
damaged rubber components, worn bearings,
looseness, and/or a deformed or cracked bracket.
– Inspect the drive axle mounts, if equipped, for excessive
wear, looseness, and/or damage.
2. Replace any of the components found to be worn or
damaged.
Did you find and correct a condition?
Attempt to duplicate the vibration in the stall. Refer to
12 "Vibration in Service-Stall Test (Non-Torque Sensitive): ".
Were you able to duplicate the vibration?
Perform the "Vibration in Service-Stall Test (Torque Sensitive):
13 ".
Were you able to duplicate the vibration?
Is the vehicle front wheel drive with an all wheel drive system?
14
1. Remove the propeller shaft.
2. Perform the "Vibration in Service-Stall Test (Torque
15
Sensitive): ".
Is the vibration still present?
Was the vibration most evident under the transmission or the
16
transfer case, if equipped?
1. If the driveline joint at the transmission or transfer case is a
U-joint, measure the prop shaft runout at the end closest to
the transmission or transfer case. Refer to "Propeller Shaft
Runout Measurement".
2. If the driveline joint at the transmission or transfer case is a
CV joint, measure the runout of the transmission or
transfer case output flange. Refer to "Transfer Case
Output Flange Runout Measurement".
17
3. If the driveline joint at the transmission or transfer case is a
coupler assembly, inspect the coupler assembly for
excessive wear, looseness, missing or broken fasteners,
and/or damage. Measure the runout of the transmission or
transfer case output flange. Refer to "Transfer Case
Output Flange Runout Measurement".
4. Replace components as necessary.
