Do not attempt to "pop" the rear seal in this manner. The rear axle adjusting nut will slam into the outer bearing race and ruin it. I just did mine yesterday, I set the nut in there and it will not clear the race.
IMHO, re-using axle seals is like taking a shower and putting your dirty shorts back on...........just my opinion.
