Propeller Shafts: 3D-24
14. Add a third clamp to the propeller shaft, next to the
first and second clamps and with the head of the
clamp directly on the light spot.
15. Observe the amount of disturbance to the propeller
shaft.
– If the amount of disturbance to the propeller shaft
appears to be significantly reduced, the balance
achieved may be sufficient and the vehicle should
be road tested to determine the effect on the
vibration concern. If necessary, continue to move
the position of the first and second clamp heads
an equal distance on either side of the light spot to
a maximum of 120 degrees apart from each other,
until the greatest amount of reduction in the
vibration disturbance is achieved.
– If the amount of disturbance to the propeller shaft
appears to be almost unchanged or even
increased after a third clamp was used on the
propeller shaft, the propeller shaft likely requires
replacement.
16. If the heavy spot of the propeller shaft could not be
identified, install a band-type hose clamp to the
propeller shaft as a weight, with the head of the
clamp directly in-line with an existing factory-
installed weight.
17. Observe the amount of disturbance to the propeller
shaft.
– If the amount of disturbance to the propeller shaft
appears to be significantly reduced, the balance
achieved may be sufficient and the vehicle should
be road tested to determine the effect on the
vibration concern. The head of the clamp can be
moved very slightly, if necessary to refine the
balance achieved.
– If the amount of disturbance to the propeller shaft
appears to be almost unchanged or even
increased, proceed to step 18.
18. Move the head of the clamp 180 degrees, directly
opposite the factory-installed weight.
19. Observe the amount of disturbance to the propeller
shaft.
– If the amount of disturbance to the propeller shaft
appears to be significantly reduced, the balance
achieved may be sufficient and the vehicle should
be road tested to determine the effect on the
vibration concern. The head of the clamp can be
moved very slightly, if necessary to refine the
balance achieved.
– If the amount of disturbance to the propeller shaft
appears to be almost unchanged or even
increased, the propeller shaft may require
replacement.
Driveline Working Angles Adjustment
NOTE
This procedure is intended to be used for
vehicles where the following conditions are
met:
• Vehicle trim heights are within
specification guidelines.
• The vehicle exhibits no signs of
aftermarket modifications that may affect
driveline working angles.
• The vehicle exhibits no signs of accident
damage which may affect the position of
the drive axle, or axles, the propeller shaft
support bearing, if equipped, or the
transmission or transfer case, if equipped.
Drive axle wind-up may cause a launch shudder
condition even when all of the driveline working angles
are within specifications. Drive axle wind-up occurs
when heavy torque during acceleration causes the
pinion nose to pivot upward. Excessively worn or
damaged axle mounting components and/or overloading
or unevenly loading the vehicle may contribute to a
launch shudder condition.
1. For solid axles equipped with a leaf spring
suspension, inspect the leaf springs, mount
bushings, and mounting hardware for excessive
wear or damage.
2. For solid axles equipped with a non-leaf spring
suspension, inspect the suspension links and link
mounts and/or bushings for excessive wear or
damage.
3. For direct-mount axles, inspect any axle mount
brackets for damage and inspect the axle mounts
and/or bushings for excessive wear or damage.
4. Inspect the structure to which the suspension
attaches to ensure no deformities or damage exists.
5. Inspect the propeller shaft support bearing assembly
for damaged rubber components, worn bearings,
and/or a deformed/cracked bracket.
6. Inspect the propeller shaft support bearing assembly
and mounting bracket, if equipped, for loose or
missing shims. Reinstall correctly or replace any
shims as necessary to ensure proper alignment of
the support bearing assembly.
7. Inspect the structure to which the support bearing
assembly attaches to ensure no deformities or
damage exists.
8. Inspect any transmission or transfer case mount
bracket or brackets for damage and inspect the
mount or mounts for excessive wear, damage, and/
or deformities.
9. Inspect the structure to which the transmission or
transfer case attaches to ensure no deformities or
damage exists.
