14. CAUTION: If any dirt, metal shavings, moisture or corrosion is found in the hub or the hub bore in the knuckle, a new hub lock vacuum
valve must be installed.
CAUTION: The wheel hub and bearing are not repairable. The bearing preload cannot be readjusted. If the bearing retaining nut on the
wheel hub and bearing is removed, a new wheel hub and bearing must be installed.
CAUTION: Do not allow the axle shaft to rest on the knuckle main seal. Failure to follow these instructions can damage the main seal.
NOTE: The wheel hub and bearing is a slip-fit design and should not require a puller tool for removal.
Remove the wheel hub and bearing. Carefully pull the axle shaft out of the knuckle. Secure the axle shaft with mechanic's wire.
15. CAUTION: Whenever the wheel hub is removed the O-ring must be installed new. Failure to do so can allow vacuum leaks causing loss of
four wheel drive operations and contamination of the hub lock vacuum system.
Remove the bearing/knuckle O-ring.
