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 ller hole in the hub; if
none, add oil through the differential
ller hole. (Note: Remember to replace
vent plug or threaded ller plug when
done.) Allow time for the oil to seep
through the bearings when initially
lling a hub. Maintain the differential
oil level by adding oil until its surface is
even with the bottom of the ller hole
(see illustration
on page 5-37).
Oil-lubricated Nondriven
Hubs
Use CD50
synthetic transmission uid
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 uid to seep
through the bearings when initially
lling a hub. When properly lled, the
uid level will lie between the uid level
line and 1/4” above the line.
NOTE
Remember to
replace vent plug when
done.
