frontier rear axle seals

my 2000 frontier 2 wheel drive just hit 94000 miles and during routine brake inspection found the right rear brake soaked with gear oil, apparently the rear seal blew. i want to know if any one knows how to get the outer seal and bearing out of the housing. the axle came out easy and the inner seal was easy to change. does any one have the repair manual page for this job. i would really appreciate any help any one can give on the rear seal problem,
