hub

An airline hub or hub airport is an airport used by one or more airlines to concentrate passenger traffic and flight operations. Hubs serve as transfer (or stop-over) points to help get passengers to their final destination. It is part of the hub-and-spoke system. An airline may operate flights from several non-hub (spoke) cities to the hub airport, and passengers traveling between spoke cities connect through the hub. This paradigm creates economies of scale that allow an airline to serve (via an intermediate connection) city-pairs that could otherwise not be economically served on a non-stop basis. This system contrasts with the point-to-point model, in which there are no hubs and nonstop flights are instead offered between spoke cities. Hub airports also serve origin and destination (O&D) traffic.

    Brakes 1979 CJ5 Hub Assembly - Removal

    I need some help here. I’ve looked everywhere for a diagram of this front hub assembly. I cannot for the life of me figure out how to get it off to replace the rotors. I’m unsure of the brand of hub. It does have 6-bolt pattern. Doesn’t look like a Warn. All the photos and videos I have looked...
