Axle Boot Help

I have a 2015 800 Outy XT. Needs a new right rear outer boot. Thought it would be easier than this, but the wheel bearing hub is permanently welded to the swing arm. Looks like I have to drop the swing arm from the top to get the axle out. Is this true?? I got the axle popped loose from the diff, but there is not enough play in the plunger-joint to get the darn thing out.

If so, is there any advice/experience I should be aware of? Thanks
