Wheel End Lubrication
IMPORTANT:
In
cases where wheel
equipment is being installed, either new or
after maintenance activity, the lube cavities
are empty. Bearings and seals must be
manually supplied with adequate lubricant
or they will be severely damaged before the
normal motion of the vehicle can supply
lube to the hub ends of the housing.
To avoid the risk of premature damage to
being installed. There are three methods of
wheel bearings and seals, they must be
doing this. The correct method will depend
“prelubed” any time the wheel equipment is
on the type of wheel equipment being used.
Lubrication When Hubs Have No Filler Holes (Preferred Method*)
(Follow procedure in numerical sequence.)
1.
Fill axle with lube through axle housing cover filler hole.
2.
Jack up left side of axle.
Maintain this position for
one minute to allow lube to
flow into wheel ends at
right side.
3.
Jack up right side of
axle. Maintain this position
for one minute to allow
lube to flow into wheel
ends at left side.
4.
With vehicle level again, add lube
through axle housing cover filler hole. The
axle should require two additional pints of
lube to bring level up to bottom of filler hole.
*The above procedure is the preferred method since it optimizes the lube supply to the
wheel end components and axle sump.
Alternate Method of Wheel End Lubrication

lubricant at installation.
CAUTION:
Exercise caution when
mounting a precharged hub and drum
NOTE:
If the hub has no cavity to accept a
assembly to prevent spilling lubricant on
precharge of axle lube, the bearings can be
the brake linings.
