a . With the differential positioned as shown in
Fig. 263, bounce the differential lightly on a flat
surface so the differentia l gears settle.
b. Measure the clearance between side gears and
the case as illustrated .
c. If the clearance exceeds .006", add shims
between the side gears and the case . To bring the
clearance within spec ified to le rance, shims in these
thicknesses are available:
.004" [0,10 mm .], . 006" [0,15 mm.], . 008 " [0,20 mm.]

Wh en shims are required, there must be at least
one shim on each side. Also, ke ep the shim pac ks

In sta lling R ea r Axle in Vehi c le
N ote: All service replacement axle assemblies are
sh i pped from the factory without lubricant in
the differentia l. Lubricant must be added to the
differential before the axles are installed in vehicles .
Us e the gr ade a nd quantity of lubricant specified
in the appropriate service manu al.
After the axle h as been inst alled in the vehicle,
check to be sure the l ubricant level in the differen-
tial is up to the filler plug ope ning.
To install the axle under the ve hicle , h ave the end
of the vehicle secur.::ly supported with a chain
hoist or a support under the fram e just a head of
the r ea r springs. Place the axle in position and raise
it so the spring clips and front spring bolts may be
installed. Ne xt connect the brake line hos e at fr ame,
i ns ta ll l ock clip and attach the brake line . Conn ect
the shock absorbers at the axle mounting pads .
Conn ect the propeller shaft at the r ear universal
joint.
Th e wheels may then be installed and the vehicle
lowered to the floor.
Bleed the brakes to remove any air from the lines,
first making certa in that there is an amp le supp ly
of brake fluid in the m aster cylinder reservoir. See
' Brake' Section for fur the r instructions. Fill the
ax le housing with the proper lub ric ant . See 'Lubri -
catio n Section'.

Identification , applicat ion, se rvicing , and trouble

in the followi ng paragraphs.
N-15 . I denti f icat ion
Powr-Lok differentials are determined by a brass
tag un der one of th e differential carrier housing
cover screws . Thi s tag is usually placed oppos ite
the ax le ratio tag as shown in Fig. 234 . Th is t'lg is
stamped either w ith a letter T or with "USE
LIMITED SLIP DIFF. LUBE ONLY."
N-16 . Powr -Lok C h anges
Th e disc type Powr-Lok differential is current ly
used on all P o wr -Lok axle assemblies . Both t he
cone type and disc type have been used on vehicl es
with the Model 44 axle . Only the disc ty;Je is no w
avai l able . However, as the disc type is int erc h ang e-
able as a comp lete assemb ly with the cone typ e,
no service problem is presented.
The disc type also has been produced .vith t wo
different types of friction plate and disc set s or
clutches. In the early disc type, all plat es and di scs
were the flat type. The late disc typ e asse mb ly
order is shown in Fig. 265 and should alway s be
used as the gu id e to properly assemblin g t he pl ate s.
