replacement, be sure to replace the entire assembly.
Check the following parts for wear, damage, noise or any
other abnormal conditions:

and check for run-out by holding the probe of a dial
indicator (1) in contact with the center part of the shaft. If
the amount of run-out is beyond the standard value for
assembly, correct with a bench press or replace the shaft
with a new propeller shaft assembly .
Standard: 0.3 mm (0.012 in)
Limit: 0.5 mm (0.02 in)

1. Install spider to flange yoke. Be sure to install the
spider by aligning the setting marks made during
disassembly.
2. Before installing needle roller bearing, apply a
molybdenum–disulfide grease or a multi–purpose
type grease NLGI No. 2 to inside of the bearing cap.
Grease Amount: Approx. 1.2 g (0.042 oz)

3. Using either a mallet (or copper hammer) or a press,
install the needle roller bearing into the yoke so that
the snap ring can be installed in its groove.
CAUTION: The needle roller bearing cannot be
installed smoothly if it is set at an incorrect angle
with the flange and excessive hammering will
damage the needle roller bearing.
