of Wheel Bearing Failure ~
life is limited by the following factors:~
~Lack of Attention to Old
~Repacking your Bearings~
During a long trailering trip, whenever we stop, I make it a habit to feel the wheel hubs, reasoning that a warm hub could spell bearing trouble. Certainly this is good practice but hubs are always warm and when really hot the cause could be an overheated hub caused by a sticking brake or dry bearings. The only sure way to check bearings is to either spin the wheel or holding hands on the rim, twist the tire feeling for any sideways movement. A slight grinding sound or a wheel with play warns of imminent bearing failure. When a bearing fails it seizes, the tire stops turning and, if towed, will blow to pieces.
Lack of lubrication is the primary cause of bearing failure. Rather than run bearings to failure, you should repack bearings once or twice a year, regardless of the distance traveled. When packing bearings, donít just apply grease to the rollers. Rather, place a glob of grease in your hand and keep dipping the bearing into the grease until grease flows out the other side. (I recommend buying a use bearing packers.) Put a little smear of grease on the outside then insert into the cup.
