Trailer (computing) In information technology, trailer or footer refers to supplemental data placed at the end of a block of data being stored or transmitted, which may contain information for the handling of the data block, or just mark its end.
On a trailer, the spindles are located at the very ends of the axles and they definitely do serve a purpose. When you're towing, spindles are the part of the trailer axle assembly that the wheel hubs (and wheels) rotate around. Trailer spindles provide a surface for the inner and outer wheel bearings to roll on -- or rather, to roll around. The inner and outer wheel bearings keep the wheel hub and the spindle from actually contacting one another. In other words, the spindles are literally at the center of it all.
