How do you take Midget wire wheel hubs off?

["Brian L. Chaffins" <bchaffin@shutter.net>]

Can anyone please give me with a hint as how they get the 4 bolts holding 
the splined hub loose from the front brake rotor? The bolts are very close 
to the hub itself and I can't get a large ratchet or wrench on to get a good 
amount of leverage? Also can't get the impact in close enough?

I'm also assuming that these 4 bolts come off first before I can remove the 
center nut to service the bearings?

Thanks
Brian
