8. Install the inner and outer bearing cups into hub (Figure 11).
9. Pre-lube the inner bearing with the lubricant that is
being retained and place it into the hub.
Failure to lubricate bearing correctly and
maintain proper lubrication could result
in bearing damage.
NOTE: If using grease and not oil for hub lubrication, the
inner and outer bearing, and the hub cavity MUST be
pre-packed with grease before installation. Lubricate
wheel end components with grease specified in
lubrication table in Section 21.
10. Push the hub onto the spindle until it contacts the seal.
Pre-lube the outer bearing with the lubricant that is
being retained and place it into the hub.
Support the hub against the spindle inner
shoulder until the outer bearing and
adjusting nut are installed. DO NOT ram
the hub into the bearing shoulder, which,
if not avoided could damage the hub seal.

Installation Instructions
1. Remove all burrs from the hub bore and spindle.
Thoroughly clean hub cavity and spindle.
2. Place the hub on a smooth, hard surface in a horizontal
position. Pre-lube the inner bearing with the lubricant
that is being retained and place it into the hub bearing
cup (Figure 12).
NOTE: When using grease, pre-pack the inner bearing
before placement into the hub.
3. With the correct head on the hub seal installation tool,
place the hub seal on the installation tool, so that the
words “Lube Side” face the inner bearing. Place the tool
(with the seal correctly mounted in the tool head) into
the hub bore. Use a three to five pound hammer to drive
against the end of the tool. Drive seal into bore until
complete bottoming is assured (Figure 13). Remove
Installation Tool and apply a thin layer of lubricant on
the I.D. surface of the seal. Ensure the inner bearing
rotates freely. Install a new seal if the seal is crooked or
damaged or after installation.
NOTE: DO NOT apply lubricant to the O.D. of the seal.
