Need to remove rear hub...

[tmontague]

based on your mileage and heavy dose of winter salt it can either be a somewhat frustrating day at home or an easy one (but potentially costly one) for a shop.

Once you have it off, if you apply anti seize to it like you should future removal is simple. I wouldn't recommend trying it at home without an air chisel, some sort of penetrating fluid and also go to a local hardware store and grab a long threaded bolt (as long as you can) and some matching nuts and various sized washers. You can make your own press to remove the dust shield from the hub if it is seized on (hint: it probably is). A torch will also help make them easier to separate.
