(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 180°,
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
Center of Shaft
Rear of Shaft
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.
