axles, you may have misaligned axles. If
you suspect rapid tire wear, have your rear
axle alignment checked and adjusted by an
authorized dealer.
Suspension alignment should be checked
when any one of the following conditions
exist:
• Total vehicle alignment required
after a body has been installed on
truck chassis.
• Discovery of loose suspension
fasteners (Loose, defined as any
torque below the recommended
torque value)
• Discovery of elongated holes in a
suspension component
• Bushing replacement
• Excessive or abnormal tire wear
• Immediately after post body
installation (See First Day in the
Maintenance Chapter)
Drive Axle - Dana
Drain the lubricant while warm. Flush each
unit with clean flushing oil. Change the
lubricant.
Eaton/Dana Axle Lubrication
• The original mineral-based
lubricant must be drained within
3,000-5,000 miles (4,800-8,000
km) on all Eaton axles. This initial
change is very important because it
flushes out break-in contaminants
that might otherwise cause
premature wear.
• No initial drain is required on Eaton
axles that are factory filled with an
Eaton-approved synthetic lubricant.
• Mineral-based lubes must be
drained within the first 5,000 miles
(8,000 km) if converting to an
Eaton-approved synthetic lube.
• Change the lubricant within the first
5,000 miles (8,000 km) of operation
after a carrier head replacement,
regardless of the lubricant type.
• Refer to the Eaton Field
Maintenance Manual for a
particular axle for lubricant
specifications.
• See your dealer for Eaton-
approved lubricant brands.
• Refer to the chart below for
lubricant change interval.
