bad hub??? HELP!

[shelby987]

OK, i need to get my truck back on the road this weekend.....the reason is a long story, but here is my issue a couple of weeks ago my truck started making noise from what sounded like bad wheel bearings, so I decided to park the truck until I could get around to pulling off the hubs and replacing the wheel bearings. Well, I finally got the time, pulled off the hubs, all the bearings appear to be in relatively good shape....but I decided to clean everything up just the same. When I cleaned off the inside of the right hub, I found what appears to be pitting of some sort, its about the size of a dime. There don't appear to be any sharp edges, though i wouldn't imagine there would be, and there also doesn't seem to be any galling at all, past the perimeter of the pitting. My question is this, can I use this hub? This is the machined surface that the bearing itself rolls over, there is no cage that fits against this surface.
If I can't can anyone point me to a place that might have a hub for a 70 d44hd front axle? (drum front 3/4t axle).
Also, what grease should I be using to reassemble these....is synthetic the way to go with michigans colder weather? I know there is specific grease for drum brakes vs. discs, and I wanted to make sure synthetic would still work ok.
ok, to make matters worse, I can't upload the picture because its too large....can someone please help me? If I try to resize it, its still to big, and if I change the format the board says dimensionally I can't upload.....AHHHH
