Can't help you, as it will pop out when it's ready,, you probably did everything correctly... (well maybe not, if you pulled the joints apart....) they sell some very nice pry bar sets for about $40.00. Though I got away with a screw driver. butt it's a crappy way to do it...
you really should replace the axle flange seals.. if you have not... as you will be very sad if you leave the old one in, and they end up leaking... (when putting them in, you must tap them into place with extreme care..)
When you go to buy them, you might get asked which models of trans you have, have that info handy.. (they might not have them in stock, call around, some stores can get them overnight,, others take up to a week...)
