Disassembly
NOTE: Follow steps 1-10 for wheel/hub removal in
‘Front Drive Shaft (CV) Service / Removal’
1.
Remove outer snap ring.
2.
From the back side, tap on the outer bearing race
with a drift punch in the reliefs 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.
Inspect the bearing.
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.
