NOTE

Change lubricant in new or rebuilt axles at

1,000 miles (1,609 km), but no sooner than

500 mi (805 km). If truck is operated in

ambient temperatures over 100 degrees F

(38 degrees C) the lubricant should be

drained and refilled every 3000 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. Oil

level should be at bottom of the hole.

Planetary wheel end level is at the bottom of

the center check plug. Fill slowly through

the 3/4 in. (19 mm) fill holes until oil runs

out the center check location. Scheduled oil

level checks will be made at these same

locations.

Axles No. 3 and 4 (non-steering axles).

Scheduled oil level checks will be made

only at the axle housing and not the

planetary wheel ends on the rigid axles.

Due to internal venting the wheel ends will

seek the same level as the axle housing, and

as a result, no checks should be made after

the initial fill/check of the wheel end.
