Assembly and Installation
10. If disassembled, assemble the inter-axle
differential.
A. Apply axle lubricant to all of the inter-axle
differential parts.
B. Install the pinion gears and the thrust washers
in the spider.
C. Place the spider and pinion assembly in
one of the case halves of the inter-axle
differential.
D. Install the remaining case half over the first
case half. Verify that the marks on each case
half are aligned.
E. Install four of the capscrews that fasten the
case halves together. Install the capscrews
so that the capscrews are the same distance
away from each other. Equally tighten the
capscrews to bring the case halves together.
F. Install the rest of the capscrews. Tighten
the capscrews to 45-55 lb-ft (60-75 Nm).
11. Install the inter-axle differential to the input
shaft so that the teeth in the differential
case are away from the helical drive gear.
Install the snap ring that fastens the case to
the shaft. Figure 5.75.

NOTE: If you replace either the bearing cap
or the cone, replace both parts in a fullymatched
set from the same manufacturer.
12. If removed, install the bearing cap for the
rear side gear into the differential case. Use
a press and a sleeve to install the cap into the
differential case. If a press is not available,
use a sleeve or a long, brass drift and a hammer
to install the cap. The cap is correctly installed
when the bottom of the cap is seated
against the bottom of the bore. Figure 5.76.

NOTE: If you replace either the bearing cap or
the cone, replace both parts in a fully-matched
set from the same manufacturer.
13. If removed, install the bearing cone onto the
rear side gear. Use a press and sleeve to
install the cone onto the gear. The cone is
correctly installed when the bottom of the
cone touches the shoulder on the side gear.
14. Install the oil filter assembly and plug in the
suction line in front of the differential. Tighten
the screen and plug assembly to 48 lb-ft (65
Nm). Figure 5.77.
