FINAL DRIVE
FRONT HUB BEARING (2x4/4x4)
Removal
1. Remove outer snap ring.
2. From the back side, tap on the outer bearing race with a
drift punch in the relief as shown.
NOTE: Drive bearing out evenly by tapping on outer
race only. Once bearing is at bottom of casting,
support casting on outer edges so bearing can be
removed.
3. Discard bearing once removed.
NOTE: Due to extremely close tolerances and
minimal wear, the bearings must be inspected
visually, and by feel. While rotating bearings by
hand, inspect for rough spots, discoloration, or
corrosion. The bearings should turn smoothly and
quietly, with no detectable up and down movement
and minimal movement sideways between inner and
outer race.
4. Inspect bearing housing for scratches, wear or damage.
Replace housing if damaged.
Installation
1. Support bottom of hubstrut housing in a press or suitable
device.
2. Start bearing in housing.
3. Press bearing into place until outer race bottoms on
housing.
4. Install snap ring into groove.
FRONT PROP SHAFT

1. Using Roll Pin Removal Tool (PN 2872608), remove the
roll pin from prop shaft at rear of housing.
2. Slide prop shaft back and away from front housing. Pull
sharply forward to remove from transmission shaft.
Installation
1. Apply anti-seize compound to all splines. Slide prop shaft
back onto the transmission housing, then connect to the
front gearcase, verify pin holes are aligned.
2. Using Roll Pin Tool (PN 2872608), install the prop shaft
roll pin at rear of housing.
CAUTION
When using an arbor press be sure to press only on the
outer race, as bearing damage may occur.
