8. Remove the bolt from the shaft. Install the 3/8” pipe plug or
breather assembly depending on shaft measured. Tighten the bolt
to 20-25 lb-ft (27-34 N∙m).
9. After performing all bearing end play measurements, if
adjustment is required, separate the transfer case halves.
10. Adjust the shims to achieve the correct bearing end play on all
shafts as required and recheck. Refer to ”End Play Check &
Adjustment” on page 63.
MTC-4213X Rear Output Shaft End Play
NOTE: Determine the rear output shaft bearing end play before install-
ing the rear cover onto the front case.
1. If the rear output shaft and cover assembly has been
disassembled, install the rear output shaft, bearing cones, spacer,
and shims, yoke into the rear cover. Temporarily tighten the yoke
nut to 700-900 lb-ft (949-1220 N∙m). Place the rear cover on the
bench to measure bearing end play. Refer to the bearing cup and
shim installation procedures in this section. Figure 6.27.

2. Rotate the output shaft several times to seat the bearings.
3. Use a suitable dial indicator setup and pry UP on the yoke to
determine bearing end play. End play should be 0.002-0.004”
(0.051-0.102 mm). To obtain a consistent reading, perform this
operation two or three times. Record the reading for this shaft.
