rear wheel bearing?

[hurleyblink]

I think i know but just asking, when doing rear wheel bearings i need the hub assembly something like, http://cgi.ebay.com/ebaymotors/ws/e...0668606307&viewitem=&sspagename=STRK:MEWAX:IT

and to get this off the car just simply remove, wheel nut, caliper, then the hub assembly. does it slide off or will i need a puller?
