Assembly
4.
Use a pry bar to lift the yoke to obtain a measurement. To
obtain a consistent and averaged reading, perform this
operation two or three times. Record the reading for this
shaft. The end play should be 0.002-0.006" (0.051-0.152
mm).
If the end play reading is not within 0.002-0.006" (0.051-
0.152 mm): Add shims to reduce end play or remove shims
to increase end play. Bearing shims come in 0.003-, 0.005-
and 0.010" (0.08, 0.13 and 0.25 mm) thicknesses.
5.
If the rear output shaft bearing end play requires adjustment,
remove the rear output shaft yoke so the case and cover can
be easily separated.
6.
Measure the end play on the remaining shafts before splitting
the case to make adjustments.
7.
After performing all bearing end play measurements,
separate the transfer case halves as necessary to adjust
shims and achieve the correct end play on the shaft requiring
adjustment.
8.
Adjust shims to achieve the correct bearing end play on all
shafts as required.
Front Output Shaft End Play (All Models)
Determine the front output shaft bearing end play before final
assembly. Seals should not be installed until the end plays are set.
1.
Install the front output shaft yoke. Temporarily tighten the yoke
nut to 700-900 lb-ft (949-1220 Nm).
2.
Rotate the output shaft several times to seat the bearings.
3.
Set up a dial indicator to check the output shaft bearing end
play. Center the dial indicator over the shaft.
NOTE: For accuracy, place a ball bearing into the recess found
on the end of the shaft, then place the tip of the dial indicator
on top of the ball bearing. Figure 7.23 and Figure 7.24.

• If the end play is greater than 0.002-0.006" (0.051-
0.152 mm): Add shims to reduce end play.
• If the end play is less than specification:
Remove shims to increase end play. Bearing shims come
in 0.003", 0.005", and 0.010" (0.08, 0.13, and 0.25 mm)
thicknesses.
• If the front output shaft bearing end play requires
adjustment: Remove the front output shaft yoke so the
case and cover can be easily separated.
5.
Measure the end play on the remaining shafts before splitting
the case to make adjustments.
6.
After performing all bearing end play measurements, separate
the transfer case halves as necessary to adjust the shims and
achieve the correct end play on the shaft requiring adjustment.
7.
Adjust the shims to achieve the correct bearing end play on all
shafts as required and recheck.
8.
Before installing the yoke, clean the splines of old silastic.
Apply a 1/8" (3.175 mm) bead of RTV 732 sealant 360
degrees around the underside of the washer. Figure 7.25.
