Standard Hub Steer Axles - Lubrication
Proper lubrication practices are important in maximizing the
service life of your steer axle hub assembly.
Wheel Bearings
Lubricate wheel bearings with an approved drive axle lubri-
cant (oil bath) or heavy duty grease (grease packed) depend-
ing on the type of axle lube system. Identify the type of
lubrication system on your vehicle before servicing wheel
bearings. Improper lubrication can result in reduced seal life
and potential damage to bearings and spindles.
Oil Bath – Lubricate wheel end assembly with a drive axle
lubricant that meets MIL-L-2105E specifications. Either
80W-90 mineral based or 75W-90 synthetic lube is accept-
able. Check lubricant level at each greasing interval. Maintain
lube level to centerline of axle or fill line on hub cap. Always
check lube level on flat ground.
Do not mix lubricants of different grades. Do not mix min-
eral and synthetic lubes. Different brands of same grade
may be mixed. Do not pack bearings with grease when
using an oil bath system. This practice can restrict the flow
of lubricant to the wheel seal.
Grease Packed – Thoroughly clean bearings, spindle, hub
cap, and hub cavity. Parts may be washed in a suitable com-
mercial solvent. Be certain parts are free of moisture or other
contaminants. Refer to vehicle and/or wheel seal manufac-
turer’s recommendations when using grease.
1. Grease bearing cones by forcing grease between
rollers, cones, and cage.
2. Coat spindle and spindle nut with lube.
3. Fill wheel hub with grease to inside diameter of bear-
ing cups.
4. Coat inside of hub cap with grease.
Never mix oil bath and grease packed wheel ends.
