Before each tow, coat the ball with a thin layer of
automotive bearing grease to reduce wear and ensure
proper operation; and check the locking device that
secures the receiver to the ball for proper operation.
If you see or can feel evidence of wear, such as flat
spots, pitting or corrosion, on the ball or receiver,
immediately have your dealer inspect them to determine
the proper action to prevent possible failure of the ball
and receiver system.
When replacing a ball, the load rating must match or
exceed the GVWR of the trailer.

the wheels, or if the trailer has struck a curb, inspect
the rims for damage. Replace any damaged wheel.

A loose, worn or damaged wheel bearing is the most
common cause of brakes that grab.
To check your bearings, jack up the trailer and secure
it on adequate capacity jack stands. Check wheels for
side-to-side looseness.
If the wheels are loose, or spin with a wobble, the
bearings must be serviced or replaced.
^
WARNING
Never go under trailer unless it is on firm
and level ground and resting on properly
placed and secured jack stands.
If your axle(s) are equipped with a grease zerk on the
ends of the axle(s), the bearings must be greased
every 6 months or 6,000 miles to ensure reliable and
safe operation of your trailer.
1.
Remove the rubber plug from the axle end.
2.
Place grease gun on zerk.
3.
Pump grease until new grease begins to appear.
Use a different color grease each time so you will
know when the new grease begins to appear.
4.
Install rubber plug and cap. Repeat for remaining
wheel bearings.
If your trailer axle(s) are not equipped with grease
zerks, refer to the axle manufacturer’s manual for
service and maintenance information.
