4. If necessary, remove the rear output shaft. Add shims to increase
end play or remove shims to reduce end play. Reinstall the rear
output shaft assembly.
5. Recheck the end play.
Front Input Shaft End Play Check & Adjustment
(All Models)
1. Set up a dial indicator to check input shaft bearing end play.
Center the dial indicator over the shaft using a ball bearing for
accuracy. Figure 6.29.

2. 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 the input shaft. The
specifi cation for MTC-4208 and MTC-4210 transfer cases is
0.002-0.006” (0.052-0.152 mm), and 0.002-0.004” (0.051-
0.102 mm) for the MTC-4213 transfer case.
• If the end play is greater than 0.006” (0.152 mm) for MTC-
4208 and MTC-4210 transfer cases, or 0.004” (0.051-
0.102 mm) for the MTC-4213 transfer case: Remove shims
to decrease end play.
• If the end play reading is less than specifi cation: Add 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.
3. If it is necessary to add or remove shims, remove the input
bearing cage and oil pump assembly capscrews and lift the
assembly enough to insert or remove shims.
• This can be done without completely removing the pump and
shaft assembly from the housing.
• The nut on the rear end of the shaft on MTC-4208 & MTC-
4210 transfer cases must be removed fi rst. Refer to the
exploded views in this manual starting on page 1.
4. When the correct shim pack is chosen, reinstall all seven input
bearing cage and oil pump assembly capscrews. Tighten the
capscrews to 85-115 lb-ft (115-156 N∙m).
5. Recheck the input shaft bearing end play. Adjust the end play as
necessary.
