universal joint bearing cups. H o l d
the cups on the spider with tape.
Mark the cups so that they will be
in their original position in relation
to the flange when they are assem-
bf
the vehicle higher than the rear.
Synthetic seals must not be cleaned,
soaked o r washed i n cleaning solvents.
6.
Using the tool shown in Fig.
10, remove the U-joint flange.
7. Check splines on the pinion
shaft to be sure they are free of burrs.
If
burrs are evident, remove them by
using a fine crocus cloth, working
in rotational motion, then wipe clean.
Apply a small amount of lubricant
to U-joint splines.
8. Install the U-joint flange using
the tool shown in Fig. 12.
9.
Install a new integral nut and
washer on the pinion shaft. (Apply a
small amount of lubricant on the
washer side of the nut.)
10.
Hold the flange with the tool
shown in Fig. 9 while the nut is be-
ing tightened.
I I. Tighten the pinion shaft nut,
rotating the pinion occasionally to in-
sure proper bearing seating, (Fig.
6)
and take frequent preload readings
until the preload is at the original
recorded reading established in step 3.
12. After original preload has
been reached, tighten the pinion nut
slowly, until an additional preload of
6 to I2 in-lbs has been added.
'The preload should not exceed
the amount shown above, or bearing
failure may result.
Under no circumstances should the
pinion nut be backed off to lessen
preload. I f this is doen, a new pinion
bearing spacer must be installed. (In
addition, the U-joint flange must nev-
er by hammered on, or pneumatic
tools used.)
13. Remove the oil seal replacer
tool from the transmission extension
housing. Install the front end of the
drive shaft on the transmission out-
put shaft.
14. Connect the rear end of the
drive shaft to the axle U-joint flange,
aligning the scribe marks made on
the drive shaft end yoke and the axle
U-joint flange (Fig. 14).
IS.
Check the lubricant level.
M a k e sure the axle is in running posi-
tion. Add whatever amount of spec-
ified lubricant is required to reach
the lower edge of the filler plug bole,
located in the carrier casting or
housing cover.
