Incorrect Oil Level

During lubricant change, fine metal particles will be observed clinging to
the magnetic fill and drain plugs of the axle. These particles are normal wear
particles from the axle components, but will cause faster than normal wear of
the axle components if allowed to circulate through the lubricant. It is
recommended that the magnetic plugs be tested, if not replaced, at each
lubricant change when petroleum-based lubricants are used, or every 100,000
miles when synthetic lubricant is used. These plugs should have sufficient
magnetic strength to pick up a 1.5-pound weight of low carbon steel. Never
replace a magnetic plug with a non-magnetic "pipe plug" as they will not keep
the lubricant clear of metal particles or seal properly.
The level of lubricant in the rear axle should be checked every 30,000
miles or annually, whichever comes first. This will ensure adequate lubricant
in the axle for proper operation.

Proper Drive Axle Lubricant Level:

• Regular inspection of the drive axle lube levels is an essential
maintenance procedure.
• Clean the area around the fill plug, which is located
approximately halfway up the axle housing bowl.
• Remove the fill plug and observe the lubricant level.
• The lubricant should be level with bottom of the hole.
• Important: The lube level close enough to the hole to be seen or
touched is not sufficient. The lube must be level with the hole.
• Correct the level as necessary.
• Re-install the fill plug and tighten to 35-50 ft-lbs.
NOTE: When checking the lube level also check the
housing breathers. Clean the breathers if dirty or replace them if
damaged.
