Fred, if you change your gearbox oil at 600 miles you will notice lots of metal particules in it. This is because the hub gearbox has to 'bed in' (run in) it's gears. Gears in the gearbox have been hardened at the factory, but they also have to "work harden" and smooth down their surfaces. This is done by the natural rubbing and sliding together of the gear teeth. This produces the metal particules during the initial running in process. There's no filter in the hub gearbox so those metal particules are circulated around over every moving part including the bearings etc. That's not good and it will shorten the life of the gearbox if you don't take out those metal bits.
That's why you need to change the gearbox oil so early.
Edit: The latest models STILL require a rear hub oil change at 600 miles. Just checked the latest manual.
