STORAGE
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 lease 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.
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.
AFTER 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).
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.
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 can cause serious injury or death.
CAUTION
DO NOT get grease or oil on brake linings or magnet face.
