X member and lock in place with retainer. Con-
nect parking brake cable to bracket on front
end of torque tube and to brake cable sheave.
Bleed rear wheel cylinders and adjust parking
brake as described in paragraphs 8-9 and 8-13.
8. Connect radius rod to rear axle. NOTE:
Normal weight of car must be on rear springs
when
tightening
radius rod pin nuts so that
rubber bushings in rod will be clamped in neu-
tral position.
5-28 REPLACEMENT OF THIRD MEMBER
HOUSING
The third member housing consists of the
torque tube and differential carrier which are
flanged and bolted together. The bolted con-
struction is for manufacturing purposes only;
torque tube and carrier are not furnished sepa-
rately for service.
The torque tube and carrier are matched and
aligned during manufacture and always must
be kept in their original
assembly.
The tube
and carrier should never be disassembled unless
it is necessary to install a new gasket to correct
an oil leak. The gasket is of special material
and substitute material should not be used.
When removing a third member housing,
after removal of rear axle assembly from car,
drill through the heads of strut rod attaching
rivets with a
Vt
6 "
drill. If rivet heads are cut
off with hammer and chisel without drilling,
the holes in strut rods and brackets will be dis-
torted.
Third member housings furnished for serv-
ice replacement are not drilled for rivets in the
strut rod
bracket.
The holes must be drilled
after the rear axle housing, third member
housing, and strut rods are assembled together.
With strut rods in normal position and without
up or down strain, drill bracket to match holes
in strut rods with
¥2"
drill. Drill through strut
rods and bracket with a
0/16"
drill, then install
bolts No. 1312923 with
lis"
lock washers and
thin nuts.
5-29 REPLACEMENT OF REAR AXLE
STRUT RODS
The front ends of the two strut rods are riv-
eted to a bracket welded to front end of torque
tube. On Series 40, and 1949 Series 50-70, three
bolts are used to attach the rear end of each
strut rod to a spring seat welded to outer end
of axle housing. On 1948 Series 50-70, a U-
shaped clip placed around the housing anchors
strut rod securely.
a. Removal
When removing a strut rod, after removal of
rear axle assembly from car, drill through the
head of rivet with a
Vt6"
drill. The rivet head
has a centering depression for this drilling
operation. If rivet head is cut off without drill-
ing the holes in strut rod and bracket will be
distorted.

b. Installation
Strut rods supplied for service replacement
an' not drilled at front end for the attaching
rivet; therefore, the holes must be drilled
after'
installation of the rod. The holes can be located
and drilled in alignment with hole in bracket
on torque tube as follows:
1.
Before installation of strut rod, scribe a
line on bracket in line with the center of rivet
hole. Using a pair of dividers set at 3 inches,
locate a center-punch mark on the scribed line
exactly 3 inche s from
center
of rivet
hole.
See
figure 5-34 view "A."
2. Install strut rod in normal position with-
out up or down strain at the bracket on torque
tube. The top edge of strut rod should be
approximately one inch from scribed line in
bracket. See figure 5-33, view "B." On Series
40 and 1949 Series 50-70, it may be necessary
