Power Train Disassembly & Assembly
Installing Tight Fit Yokes and
the POSE
TM
Seal
CAUTION : Make sure that the seal lips are clean
and free from dirt and particles that can cause a leak
between the yoke and the POSE
TM
seal.
1. Inspect all surfaces of the yoke hub for damage.
2. Apply axle lubricant to the seal.
If carrier uses a POSE
TM
element, install a new
POSE tm seal as follows:
3. Lightly lubricate the yoke journal with same
lubricant used in the axle housing.
4. Partially install the POSE
TM
seal onto the yoke to
1/4 inch-1/2 inch (6.4 - 12.7 mm) as shown
NOTE : Do not install the POSE
TM
seal all the way
against the yoke shoulder. This seal is designed to
position itself as yoke is installed.
5. Lubricate the yoke again with the same lubricant
used in the axle housing before installing the yoke
onto the drive pinion.
6. Slide the yoke over the input shaft pinion. Align the
yoke splines with the shaft splines.
CAUTION : Do not use a hammer or mallet to install
the yoke to the input pinion shaft. Using a hammer or
mallet can damage the yoke flange.
CAUTION : Do not install tight fit yokes on shafts
using a hammer or mallet. Using a hammer or mallet
can damage the yoke.
7. Install the input yoke flange onto the drive pinion
shaft. The yoke must be fully seated against the
outer differential bearing before the nut is torqued
to specifications.
8. Install the drive pinion nut on the input pinion shaft
and against the yoke collar. Tighten the nut against
yoke collar to a torque of 922 to 1132 lb•ft (1250 to
1535 N•m)
Assemble the Main
Differential and Ring Gear
Assembly
CAUTION : Do not press a cold ring gear on the
flange case half. A cold ring gear will damage the
case half because of the tight fit. Metal particles
between the parts will cause gear runout that
exceeds the specification of 0.008 inch (0.200 mm).
1. Expand the ring gear by heating the gear in a tank
of water to a temperature of 160˚F to 180˚F (71˚C-
82˚C) for 10 to 15 minutes. Do not use an open
flame such as a torch to heat the ring gear.
