WHEEL BEARINGS

WHEEL BEARINGS

Trouble-free trailering depends upon proper bearing lubrication, maintenance and inspections. Bearings fail when lubrication fails or when improperly adjust- ed. In both cases, heat build up occurs. Normal bearing operating temperate is up to 140° and can be touched by hand without burning. Above this temperature, the grease will start to fail and destroy the bearings, drum and/or the spindle. Brakes are designed to operate at up to 600°F. A good practice for both experienced and new trailer owners is to touch each hub within ten miles of starting out when bear- ings have been repacked and at each stop along the way. (Do not try testing the hub after several miles of continuous hard braking). This will give an advanced warning of pending trouble so corrections can be made prior to fail- ure and breakdown. Remember, inactivity can be more damaging to bearings than every day use. When a trailer is parked, many times the spindle, bearings INACTIVITY CAN BE MORE DAMAGING TO BEARINGS THAN EVERYDAY USE

or hub is warm. As these cool down, a spot of condensation forms which is the start of a rust spot. The longer the trailer sits idle, the deeper this rust spot becomes. When in doubt of the coverage of grease on bearings—inspect and replace those that have rust spots, metal flaking, wear, cage damage or other visual damage.
