Just got done putting mine back in so here you go-
Ya don't need to pull the brake caliper off!!!
All you have to pull on the brake side is the bracket that holds the speedo sensor/ then get a hammer and a 3/8 extension bar,set the brake and tap the nut off the rotor end.This supports the shaft on the bearings
Undo the bolt in the hollow drive shaft ( loosen for now) and removed the nuts around the DD.. If yours has reverse there are two nuts hiding in the foot well area, and hard to see. Once all undone- and the rubber dampner removed from infront the DD- go and remove the thru bolt that was only loosened. (Take the wiring apart on the reverse motor connections)
Remove the DD case
It might take some prying to pull the axle out as rust forms around the bearing races on the brake side. Ensure that the track extroverts are free from the track. Once removed I had to buff my drive shaft to remove the surface rust and the races on the bearing..went back with never seize-and all slopped back together.
Don't forget to peen the nut on the rotor so it doesn't back off- I also applied blue loctite for a just in case
