Axle won't go in far enough

Ok guys thanks so much for your help. From the sounds of it I probably had it last night I was just worrying too much (being my first time). I have to go home for the holidays tonight but I will try it next week when I get back in town and let you know. I don't own a deadblow but I'll put a block of wood in there and use my 4 lb sledge to set the bearings. THANKS AGAIN!!!
