Removing rear pinion to change seal.

How do you get the pinion out to change the seal?... i have the d shaft out, changed the u joints, changing the output shaft seal, fixing the pump rub with jb weld, and going to change the pinion seal since it looks to be leaking all over the diff... how do you get the pinion out? Just remove the nut and get some sort of puller on the balancer and it all comes off ? OR does the balancer come off first? And where the hell do you find a 12 point socket that big?
