Wheel Bearing Lubrication
Oil-lubricated Driven Hubs
Use hypoid oil, A.P.I.-GL-5 SAE
75W-90FE synthetic gear lubricant
or equivalent. A minimum of 1 quart
(921 ml) of oil is required for proper
lubrication of each drive hub. Add oil
through the filler hole in the hub; if
none, add oil through the differential
filler hole. (Note: Remember to replace
vent plug or threaded filler plug when
done.) Allow time for the oil to seep
through the bearings when initially
filling a hub. Maintain the differential
oil level by adding oil until its surface is
even with the bottom of the filler hole
(see illustration on page 5-42). Oil-lubricated Nondriven Hubs
Use CD50 synthetic transmission fluid
SAE 50W or equivalent. A minimum of
9 oz. (270 ml) of lubricant is required
for proper lubrication of an LMS™ hub;
10-13 oz. (295-400 ml) is required for
a non-LMS hub, depending on wheel
design. Allow time for the fluid to seep
through the bearings when initially
filling a hub. When properly filled, the
