Lubrication
Proper lubrication practices are important in maximizing the
service life of your steer axle assembly.
Kingpins, Thrust Bearings and Tie Rod Ends
On-Highway Applications - Standard
Pressure lubricate every 6 months or 25,000 miles (40,000
km).
A more frequent lubrication cycle is required for axles used in
on/off highway, refuse, or other severe service applications.
Use heavy-duty, multipurpose lithium base (#2 grade) grease.
Do not mix with sodium base grease.
Note: If it is difficult to grease either the upper or lower bushing,
try greasing the bushings with the vehicle jacked up
and supported on axle stands to improve grease flow
and help flush out contamination.
Wheel Bearings
Lubricate wheel bearings with an approved drive axle lubricant
(oil bath) or heavy duty grease (grease packed) depending
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-2105D specifications. Either 80W-90 mineral
based or 75W-90 synthetic lube is acceptable. 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 mineral
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 commercial solvent. Be
certain parts are free of moisture or other contaminants. Refer
to vehicle and/or wheel seal manufacturer’s recommendations
when using grease. Fill wheel hub with grease to inside diameter
of bearing cups. Fill hub cap. Grease bearing cones by
forcing grease between rollers, cones, and cage.
Never mix oil bath and grease packed wheel ends.
