Synchronizers
The synchronizer hubs and sliding sleeves are a
selected assembly and should be kept together as
originally assembled.
Clean synchronizer components with clean solvent and
air dry.
Inspect the components for the following:
Teeth for wear, scuffs, nicks, burrs or breaks.
Keys and springs for wear, cracks or distortion,
replace if these conditions are present.
If scuffed, nicked or burred conditions cannot be
corrected with a soft stone or crocus cloth, replace
the component.

Reassembly
Transfer Reassembly
The rear cover oil seals and the rear output shaft ball
bearings cannot be reused. They must be replaced with
new ones when the transfer is reassembled.
1.
Use the oil seal installer (5-8840-2785-0) to press
the new input shaft and/or front output shaft oil seals
into place (If replacement is required).
2.
Use a press to install the ball bearings to the front
output shaft. Be sure that the bearings are fully
inserted and then install the snap ring.
3.
Install the damper ring and the internal gear to the
transfer case. Be sure that the damper ring is
between the internal gear and the case.
