Install the Upper Rear Output Shaft
(MTC-4213X Only)
1. Position the output shaft under the rear transfer case half. Use an
appropriate lifting device to place the shaft and transfer case into
a press.
2. Use bar stock or other material to support the rear output shaft
underneath the rear transfer case half. Ensure the bar stock
does not rest under the transfer case mounting fl ange, but only
supports the gear and shaft assembly. Figure 6.19.

is vertical and not leaning.

being replaced, install a starting shim pack thickness of 0.036”
(0.91 mm) or use the same thickness as removed. Figure 6.20.

6. Install the yoke, washer, and locknut. Tighten the lock nut to
700-900 lb-ft (949-1220 N∙m).
7. Use a dial indicator to check the end play on the rear upper output
shaft. Refer to ”End Play Check & Adjustment” on page 63. The
end play must be 0.002-0.004” (0.051-0.102 mm). To adjust the
end play, remove the rear output shaft and outer bearing cone
and add or remove shims, as necessary, to achieve the correct
end play.
NOTE: The end play for the MTC-4213X upper rear output can be
completed before installing the rear case half onto the front case
half.
