When I did mine I had access to a press and a mate who's rather handy with a spanner.
You'll probably find the following:
-Hub nut (driveshaft bolt) is pretty tight, but a breaker bar and some foul language should see you through.
-Steering tie rod bolts (on the underside) will probably not unbolt and need to be angle-grinded off and replaced
-Hub and upright may (or may not) be damaged, you will only be able to tell once it's all off. New hubs are about 40 quid from GSF if I remember. Second hand uprights are easy to come by.
I would say why not give it a go if you're confident. You can always take the upright assembly (upright, hub and bearing) to a garage to replace the bearing, which should save you some dosh and will make sure the bearing is in properly without damage.
Your camber and tracking will most likley be wonky when you put it all together again though.
