INSPECTION
I Check JOU~M~ for axial play If
play exists, replace propeller shaft
assembly
Note Journal cannot be disassem-
bled.
2 Check the propeller shaft tube
surface for dents or cracks If neces-
sary, replace propeller shaft assembly
REMOVAL
1 Raxe car on hoist
Remove front exhaust tube and
heat siueld plate to free them from car
body
2 Scribe match marks both on pro-
peller shaft and companion flange
so
that shaft can be reinstalled III the
anginal position
3 Remove bolts securing shaft to
companion flange
4 Draw out propeller shaft sleeve
yoke from transmission by moving
shaft rearward, passing it under rear
axle
Watch for oil leakage from trans-
mission rear end Take proper action if
oil leak is dlscovered
Note Remove propeller shaft care-
fully so as not to damage the splme,
sleeve yoke
or rear oil seal
INSTALLATION
To mstall, reverse the foregoing
removal procedure
CAUTION:
Align propeller shah with companion
flange using reference marks prescrib-
ed in
"Remod" procedure and
tlghten them wlth bolts. Failure to
do so could result in driwng vibration.

CHECKING AND
CORRECTING UNBALANCED PROPELLER SHAFT
To check and correct an unbalanc-
ed propeller shaft, proceed as follows
1 Remove undercoating and other
foreign material whch could upset
shaft balance, and check shaft nbra-
tion by road test
2 If shaft vibration is noted during
road test, disconnect propeller shaft
at
differential carrier companion flange,
rotate companion flange
180 degrees
and reinstall propeller shaft
3 Again check shaft vibration If
vibration still persists, replace pro-
peller shaft assembly

Note
a Securely attach puller to bearing
inner race, utilizing two grooves
in
ddferential case

2 Remove ring gear by loosening
ring gear bolts
Note
Loosen bolts dlagonally
3 Punch off pinion mate shaft lock
pin from ring gear side using Sold
Punch KV3
1 100300
Note Lock pin is caulked at pin hole
mouth
on differential case Do not
punch it off forcibly without
checking
how it is caulked
4 Draw out pimon mate shaft and
remove thrust block, pimon mate
gears, side gears and thrust washers
Note Put marks on gear and thrust
washer
so that they can be re-
installed in theu oripnal positions
from which they were removed
INSPECTION
Thoroughly clean all disassembled
parts, and examine them to see that
they are worn, damaged
or otherwise
fdulty and how they are affected
Repdir or replace all faulty parts,
whichever is necessary
1 Check gear teeth for scoring,
cracking or chipping, and make sure
that tooth contact pattern indicates
correct
meslung depth If any damaged
part is endent, replace parts
as re-
quired
Note. Drive pinion and drive gear are
supphed for replacement as a set,
therefore, should either part be
damaged, replace
as a set
2 Check pmion mate shaft, thrust
block, and pmion gears for scores and
signs of wear, and replace as required
Follow the same procedure for side
gears and their seats
on differential
case
3 Inspect all bearing races and
rollers for scoring, clupping or
evldence of excessive wear They
should be in tiptop condition such as
not worn and with rmrror-lke sur-
faces Replace if there
is a shadow of
doubt
on their efficiency, as an incor-
rect beanng operation may result
in
noise and gear seuure
