5. Press the bearing cups into the rear output bearing
cage. Use the correct size driver.
6. Press one bearing cone on to the rear output shaft
until it is flat against the shoulder. Be careful not to
damage the roller cage, use a sleeve that presses
against the inner race only.
7. Install the ring gear and snap ring on the output

Check Bearing End Play
The rear output bearing end play is controlled by the
spacers between the bearings. If the original bearings
are used when reassembling the transfer case, the
original spacers should provide the correct end play. If
new bearings are installed, these spacers may have to
be changed. Use the following procedure to check the
end play:
1. Install the bearing cage/output shaft assembly on the
transfer case with two capscrews and washers.
