what i think he means is to unbolt both axles, unhook driveshaft, remove steering linkage and unplug the diff actuator then you can unbolt all the differental mounting bolts except for the one at the rear bushing, this allows diff to swing down so you can remove the stubshaft. this is the prefered method and alot easier if the axle doesn't want to come out. since you already have the F.L. corner apart you should try to tap/pry it out first. most of the time the snapring isn't a problem just make sure it's on the shaft before you tap it back in
