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.
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.

Inspection Procedure
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.
Storage
11. Mount and tighten wheels per instructions in manual.

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 trailers total weight is
on the hitch. For light trailers this should be increased to 15%.
6. Do Not Overload. Stay within your gross vehicle rated capacity (consult
