[A/S] Re: Wheel Bearings

["nickcrowhurst" <NickandSandra@xxxxxxxxxxx>]

The usual explanation for this apparaent anomaly is that trailer 
wheels suffer conditions unlike that of car wheels. In particular, 
when reversing a multi-axle trailer at an angle, there are enormous 
side forces on the wheels. (Just look at the tire distortion under 
such conditions.) The additional explanation is that trailers often 
sit idle for months at a time. Under those conditions, some greases 
dry out, harden, crack, and loose their lubricating qualities. I'm 
just passing on what I've read. I check mine when I take the drums 
off to check the brakes, and I do it for peace of mind. Nick.
