General Information
5. Rotate the pinion flange or the transmission yoke
by hand while taking the measurements for the
run out.
Important: The propeller shaft turns easier in
one direction than in the other. Removing the wheels
will also help. Do not include fluctuations on the
dial indicator due to welds or surface irregularities.
6.
Perform the following steps for one-piece propeller
shafts if the runout exceeds the tolerances at
one or more points:
6.1.
Rotate the propeller shaft
180
degrees in
the pinion flange.
6.2. Reinstall the propeller shaft.
6.3.
Measure the propeller shaft runout.
6.4. If the runout still exceeds the tolerance,
inspect the pinion flange runout before
replacing the propeller shaft.
7. Perform the following steps for two-piece propeller
shafts if the runout exceeds the tolerances at
one or more points:
Vibration Diagnosis and Correction 0-53
Important: The runout of the rear splines on the front
propeller shaft affects the runout of the front
measurement on the rear propeller shaft.
7.1.
Measure the rear propeller shaft.
7.2. Mark the position of the rear shaft in the
pinion flange.
7.3. Remove the rear shaft.
7.4. Measure the front propeller shaft runout on
the tube and the stub shaft.
7.5.
Replace the propeller shaft if either
measurement is out of tolerance. Refer
to Propeller Shaft Runout Specifications.
important: When you replace a propeller shaft,
inspect the new shaft for runout. Inspect the pinion
flange runout if the replacement shaft runout is also out
of tolerance.

4. Install the J 35819.
If a J 35819 is not available, measure the pinion
runout as close as possible to the pinion flange.
Important: The dial indicator will have inverted
readings. You are measuring the inside diameter of
the flange; you are not measuring the outside
diameter. The highest reading on the dial indicator is
the low spot. The lowest reading is the high spot.
5. Rotate the pinion shaft 360 degrees and zero the
dial indicator on the low spot.
