Front Axle
33–01 Knuckle Pin Lubrication,
Meritor Axles
CAUTION
Use regulated pressure when lubricating the
knuckle assemblies, otherwise damage could re-
sult to the knuckle caps.
When lubricating knuckle pin bushings, do not raise
the front axle. Wipe the lube fittings clean, and apply
multipurpose chassis grease, NLGI Grade 1 (6% 12-
hydroxy lithium stearate grease) or NLGI Grade 2
(8% 12-hydroxy lithium stearate grease) until new
grease is seen at the bushing grease seal opposite
the fittings. The grease seal will accept grease pres-
sure without damage, and is designed to have
grease pumped out through it during lubrication.
Even if grease leaks out around the top, or bottom-
plate gasket, continue pumping until new grease is
seen at the bushing seal opposite the grease fitting.
See Fig. 1.
