Trailer 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
trailer frame so that the weight will be off the tires.
Never jack up or place jack stands on the axle tube
or on the equalizers.
3. Lubricate mechanical moving parts that are
exposed to weather, such as the hitch and suspen-
sion parts.
NOTE: 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
Procedures
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.

magnets should check 3.2 ohms. If shorted or worn
excessively, replace.

temperature brake lubricant. (Lubriplate or equiva-
lent).
