ADJUSTABLE CHANNEL
Your trailer may be equipped with an adjustable channel
(Figure 37) that allows the coupler to be raised or lowered
to a desired height. Periodically check the channel bolts
for damage or loosening.
Figure 37. Adjustable Channel
Wheel Bearings
Wheel bearings (Figure 38) must be inspected and
lubricated once a year or 12,000 miles to insure safe
operation of your trailer.
If trailer wheel bearings are immersed in water, they must
be replaced.

DANGER
If trailer wheels are under water for a long period of
time, wheel bearings may fail. If this is the case, service
wheel bearings immediately.
The possibility exists of the wheels falling off causing
equipment damage and severe bodily harm even death!
If the trailer has not been used for an extended amount
of time, have the bearings inspected and packed more
frequently, at least every six months and prior to use.
Follow the steps below to disassemble the wheel hub and
service the wheel bearings. See Figure 38.
Figure 38. Wheel Hub Components
After removing the dust cap, cotter pin, spindle nut and
spindle washer, remove the hub to inspect the bearings
for wear and damage.
Replace bearings that have flat spots on rollers, broken
roller cages, rust or pitting. Always replace bearings
and cups in sets. The inner and outer bearings are to
be replaced at the same time.
Replace seals that have nicks, tears or wear.
Lubricate the bearings with a high quality EP-2
automotive wheel bearing grease.
