Think I have a bad wheel bearing

[KiltedBanshees93GT]

How hard is it to get the axle out? Ive read the manuel, but I'm very nervous about cracking open the rear on our only running car. (I've got a low (almost subsonic) "grumbling" or "grunking" sound coming from my rear, it does change tone during acceleration, but not much (hard to tell due to the exhaust noise), and seems better or worse on long turns depending on directions (left turn is a bit quieter).

Without using "manuel-speak" how hard is it to pull the axle/reinstall? What should you use to pull the bearing? Rent a puller from the store? Is there an easier way?

Are there any steps to determine exactly where the problem lay? I had something similar happen on my 66, but after the bearings were replaced, the car still does it. (has to be the pumpkin itself, Loud rubbing "grunking" sound on tight low speed turns after the car gets warm)

Thanks,
J
