Steer Axle
Steer Axle Lubrication Procedure
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 applica-
tions.
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 bush-
ing, 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 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-2105D specifications. Either 80W-90 mineral
based or 75W-90 synthetic lube is acceptable. Check lubri-
cant level at each greasing interval. Maintain lube level to
center-line 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 commercial solvent. Be
certain parts are free of moisture or other contaminants.
Refer to vehicle and/or wheel seal manufacturer’s recom-
mendations 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.
