MC-9 MAINTENANCE MANUAL
REASSEMBLY - AXLE CENTER TO STEERING
KNUCKLE
THRUST BEARING INSTALLATION
The earlier MC-9 front axle does not have a seal at the thrust
bearing under the steering knuckle. The later MC-9 front axles
have a seal at the thrust bearing.
NOTE: Some of the thrust bearings used in
front axles have the word "TOP" stamped
on the flat face of the bearing retainer. The
stamped word "TOP" should not be used
for bearing installation purposes. Refer to
the following instructions for proper bear-
ing positioning.
Prior to putting the thrust bearing in the axle center-knuckle
assembly, if the bearing has a seal, assemble the bearing and
seal by holding the bearing so that the opening between the
bearing cage and the retainer is up. Then snap the seal securely
over the opening. See figure 1-19.
