DRIVE AXLE
General information
Drive axles generate small metal wear particles at a fairly steady rate, especially during the break-
in period. If these fine, but hard particles are allowed to circulate in the lubricant, along with
external moisture and dirt, internal components will wear at a much faster rate than normal.
Magnets and magnetic drain plugs
Planetary axles are equipped with magnetic drain plus that have a minimum pick-up capacity of
0.57 kilograms(20 ounces) of low carbon steel. The drain plug must be checked for metal particles
at every oil change interval.
Hyundai recommends replacing the magnetic drain plug each time the oil is changed.
Use the correct part. Pipe plugs will leak if used as a drain plug.
The magnetic drain plug can be reused if, after cleaning, the plug has a minimum pick-up capacity
of 0.57kilograms(20 ounces) of low carbon steel.
Breather
Cover the breather when steam cleaning the housing. If the breather is not covered, water
can enter the housing and contaminate the oil.
Breathers release pressure and vacuum condensation to minimize premature oil and component
failure.
Oil level
Check and adjust oil
For complete fill procedures for wet side brakes, refer to 3-40, wet disc brakes.
To prevent serious eye injury, always wear safe eye protection when you perform vehicle
maintenance or service.
Fill and drain plugs are located in both brake housing and the main housing.
Make sure the vehicle is on a level surface.
For axles with a common oil level that have drain and fill plugs only in the axle assembly, proceed
to step .
Rotate the wheels so that the "Oil level lines" on the wheel ends are parallel to the ground.
Clean the area around the fill/level plug.
Remove the fill/level plug from the wheel
ends and the axle housing bowl. The oil
level must be even with the bottom of the
hole of the fill/level plug.
