Wheel End Lubrication

IMPORTANT:

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.)

Fill axle with lube through axle housing cover filler hole.

Jack up left side of axle.

Maintain this position for

one minute to allow lube to

flow into wheel ends at

right side.

Jack up right side of

axle. Maintain this position

for one minute to allow

lube to flow into wheel

ends at left side.

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

After the wheel hub seal has been installed,

prepacked with a good quality grease instead

charge the hub cavity with as much axle

of axle lube. However, excess grease should

lubricant as possible.

be removed.

Prelube the bearings with clean axle

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.

Hubs Equipped with Lube Filler Holes

Pour a pint of standard axle lubricant into
