When using an oil bath system, do not pack the
bearing with grease. Grease will prevent the
proper circulation of axle lubricant and can cause
premature wheel seal and bearing failure.
CAUTION
!
1. Place the hub, seal end up, on
a clean work bench surface.
If you are working on a drive or trailer hub, go to
step 3. If you are working on a steer hub, proceed
as follows.
NOTE
2. For steer hubs, install the
tubular bearing spacer with the
tapered end down (see gure
77).

3. Lubricate the inner bearing
cone with the same lubricant
as will be used in the hub and
install it into the inner bearing
cup (see gure 78).

The seal must be replaced every time the hub is
removed from the spindle.
Do not apply any gasket sealant to the seal outer
or inner diameter.
Always use the seal installation tool specied by
the seal manufacturer. Using an improper tool can
distort or damage the seal and cause premature
seal failure.
NOTE
4. Position the seal into the hub
bore. Use a ConMet seal
installation tool or at plate and
a small mallet to install the seal.
ConMet seals require the proper tool for
installation. Refer to the table below for a ConMet
seal installation tool or at plate dimensions. For
other seals, refer to the specic manufacturers’
instructions.

5. When installing the ConMet
seal, tap the adapter plate of the
installation tool around the outer
edge to position the seal. Drive
the wheel seal into place (see
gure 79). Once the tool bottoms
out, the seal is installed correctly.

6. Check to be certain the seal is
not cocked and that the seal
inner diameter and the inner
bearing turn freely.
Failure to lubricate the inner diameter of the seal
may result in premature seal failure.
CAUTION
!
7. Lubricate the inner diameter of
the seal with a light lm of the
same lubricant as will be used
in the hub.
8. Turn the hub over, and place it
seal end down. For all drive and
trailer hubs, install a bearing
spacer. If the spacer has a
tapered end, it should face
towards the outboard end of the
hub (see gure 80).

9. Lubricate the outer bearing
cone with the same lubricant
as will be used in the hub and
install it into the hub assembly
(see gure 81).
