1. Clean out axle housing and cover.
2. Install four temporary studs, four or five inches long in
the holes on the carrier face of the axle housing.
3. Install new differential carrier gasket over temporary
studs.
4. Move carrier into position on roller jack. Start carrier
over temporary studs and into housing, using flat wash
ers under stud nut or bolts at four points. Tighten alter
nately and evenly until carrier is in position. Replace
temporary studs and flat washers. Install lock washers
and bolts at all locations and tighten to specified torque.
NOTE: Driving carrier into housing w ith a hammer
may distort the carrier flange and result in oil leaks.
5. Install shaft unit and connect lead wires to harness plug
or air line to piston housing cover on Piston-Air units.
6
. Assemble rear universal joint.
NOTE: This propeller shaft to pinion flange fastener
is an important attaching part in that it could affect
the performance of vital components and systems,
and/or could result in major repair expense. It must
be replaced w ith one of the same part number or
w ith an equivalent part if replacement becomes
necessary. Do not use a replacement part of lesser
quality or substitute design. Torque values must be
used as specified during reassembly to assure
proper retention of this part.
7.
Install axle shafts as covered under "Axle Shaft Re
moval and Installation" in the Truck Service Manual,
Eaton Single Speed.
