TRAILER WHEEL BEARINGS

The trailer axles are equipped with a grease fitting to allow lubrication of the wheel bearings without the need to
disassemble the axle hub. To lubricate the axle bearings, remove the small rubber plug on the grease cap, attach a
standard grease gun fitting to the grease fitting and pump grease into the fitting until new grease is visible around
the nozzle of the grease gun. Use only a high quality grease made specifically for lubrication of wheel bearings. Wipe
any excess grease from the hub with a clean cloth and replace the rubber plug when finished. The minimum
recommended lubrication is every 12 months or 12,000 miles (19,312 km). More frequent lubrication may be required
under extremely dusty or damp operating conditions.
