I removed the hub and when i put the centre gear part back in i didnt line up the two tabs on the gear to the hub. So it wouldn't lock in.
Not sure if this helps but theres really not much to the auto hubs.

I haven't pull the hubs apart yet. I might do that and see if I can see something. How do they come apart?
