7. Pump grease into the grease fitting in the
spindle end with a manual type grease gun
only.
Do not mix Lithium, Calcium, Sodium or
Barium complex greases due to possible
compatibility problems. When changing
from one type of grease to another, it is
necessary to disassemble the wheel bearing
and ensure all grease is removed prior to re-
packing or servicing the wheel bearing.
Failure to ensure greases are not mixed may
result in wheel bearing, axle end, hub,
MMP-4 or tow vehicle damage.
8. Rotate wheel while pumping grease into
fitting.

perform annual wheel bearing service and
inspection may result in damage to the axle,
wheel bearings or MMP-4 if not preformed.
