Following initial drain, change lubricant

(Axle No. 3)

every 12,000 mi (19,312 km) or each two

years of service, whichever comes first. If

truck is operated in ambient temperatures

over 100 degrees F (38 degrees C) the

lubricant should be drained and refilled

every 3,000 mi (4,828 km). During all

lubricant changes, remove metal particles

from magnetic drain plugs. Fill wheel ends

first.

Initial fill and level checks for the axles will

be made from the housing side plugs. Level

should be set at the bottom of the hole.

Some oil will transfer from the wheel end to

the axle housing and a slight overfill

condition at the axle housing may be

noticed during checking of the axles. This

is considered normal and should not be a

reason for concern.
