MAINTENANCE (CONTINUED)
BEARING LUBRICATION – GREASE
Along with bearing adjustment, proper lubrication is essential to the proper function and reliability of
your trailer axle. Bearings should be lubricated every 12 months or 12,000 miles (19,312 kilometers).
The method to repack bearing cones is a follows:
1. Place a quantity of grease into the palm of your hand.
2. Press a section of the widest end of the bearing into the outer edge of the grease pile closest to
the thumb forcing grease into the interior of the bearing.
3. Repeat this while rotating the bearing from roller to roller.
4. Continue this process until you have the entire bearing completely filled with grease.
5. Before reinstalling, apply a light coat of grease on the bearing cup.
BEARING LUBRICATION – OIL
If your axles are equipped with oil lubricated hubs, periodically check and
refill the hub as necessary with high quality hypoid gear oil to the level
indicated on the clear plastic oil cap. The oil can be filled from either the oil
fill hole, if present, in the hub or through the rubber plug hole in the cap
itself.
CAUTION
DO NOT mix Lithium, calcium, sodium or barium complex
greases due to possible compatibility problems.
When changing from one type of grease to another, it is
necessary to insure all the old grease has been removed.
