Storage Preparation
If your trailer is to be stored for an extended period of time or over
the winter, it is important that the trailer be prepared properly.
1. Remove the emergency breakaway battery and store inside,
out of the weather. Charge the battery at least every 90
days.
2. Jack up the trailer and place jack stands under the trailer
frame so that the weight will be off the tires. Follow trailer
manufacturer’s guidelines to lift and support the unit. Never
jack up or place jack stands on the axle tube or on the
equalizers.

!

CAUTION

Do not lift or support the trailer on any part of the axle
or suspension system. Never go under any trailer unless
it is properly supported on jack stands which have been
rated for the load. Improperly supported vehicles can
fall unexpectedly and cause serious injury or death.
3. Lubricate mechanical moving parts such as the hitch, and
suspension parts, that are exposed to the weather.

Storage

4. Boat trailer axles are subject to repeated immersion. Before
storing, remove brake drums; clean, dry and re-lubricate
moving brake components; inspect bearings - clean and
re‑lubricate.
5. On oil lubricated hubs, the upper part of the roller bearings
are not immersed in oil and are subject to potential
corrosion. For maximum bearing life, it is recommended
that you revolve your wheels periodically (every 2-3 weeks)
during periods of prolonged storage.

-82-

Before removing trailer from jack stands:
1. Remove all wheels and hubs or brake drums. Note which
spindle and brake that the drum was removed from so that it
can be reinstalled in the same location.
2. Inspect suspension for wear.
3. Check tightness of hanger bolt, shackle bolt, and U-bolt nuts
per recommended torque values.
4. Check brake linings, brake drums and armature faces for
excessive wear or scoring.
5. Check brake magnets with an ohmmeter. The magnets
should check 3.2 ohms. If shorted or worn excessively, they
must be replaced.
6. Lubricate all brake moving parts using a high temperature
brake lubricant (LUBRIPLATE or Equivalent).

CAUTION
Do not get grease or oil on brake linings or magnet face.
7. Remove any rust from braking surface and armature surface
of drums with fine emery paper or crocus cloth. Protect
bearings from contamination while so doing.
8. Inspect oil or grease seals for wear or nicks. Replace if
necessary.
9. Lubricate hub bearings. Refer to procedure in manual.
10. Reinstall hubs and adjust bearings per instructions in
manual.
11. Mount and tighten wheels per instructions in manual.

After Prolonged Storage
Inspection Procedure

Trip Preparation Checklist
There are a number of simple rules to follow in caring for your
trailer axle assembly that can add to its life and in the case of
some of these rules, you may be protecting your own life as well.
Using the following checklist before starting a trip with your trailer
is highly recommended. Some of these items should be checked
2-3 weeks prior to a planned trip to allow sufficient time to perform
maintenance.
1. Check your maintenance schedule and be sure you are
up‑to-date.
2. Check hitch. Is it showing wear? Is it properly lubricated?
3. Fasten safety chains and breakaway switch actuating
chain securely. Make certain the breakaway battery is fully
charged.
4. Inspect towing hookup for secure attachment.
5. Load your trailer so that approximately 10% of the trailer’s
total weight is on the hitch. For light trailers this should
be increased to 15%. Fifth wheel type trailer should have
15‑25% weight on the hitch.
6. Do Not Overload. Stay within your gross vehicle rated
capacity (consult your trailer’s identification plate).
7. Inflate tires according to manufacturer’s specifications;
inspect tires for cuts, excessive wear, etc.
8. Check wheel mounting nuts/bolts with a torque wrench.
Torque in proper sequence, to the levels specified in this
manual.

Storage

9. Make certain the brakes are synchronized and functioning
properly.
10. Check tightness of hanger bolt, shackle bolt, and U-bolt nuts
per torque values specified in manual.
11. Check operation of all lights.
12. Check that your trailer is towing in a level position and adjust
hitch height if required.
