ATP 500 Rear Axle Seal Leak

Hey Guys,
I have a quick question regarding my 2005 ATP 500. I seem to have a pretty bad leak coming from the seal between my axle tube and the gear housing itself. After looking on line, it looks to be an o-ring between the two pieces. my question is, can i simply unbolt this side of the axle and remove the axle tube and shaft or is it more to it than that? For instance on my ole’ chevy truck, you have to knock a pin out of the gear case before the axle will come out. Not really familiar with the strait axle atv’s. Thanks for any input in advance!
