**IMPORTANT** carrier bearing removal

**IMPORTANT** carrier bearing removal
I pulled my carrier and found out that both carrier bearings were chewed up like some dirt or metal shavings got caught in them and im assuming thats what was making the horrible noise described in the other thread
now...I've got the replacements, BUT i cant get the old bearings off. I'm using a slide hammer right now, with a 2 jaw set up. and I've got 3 different 3-jaw pullers those don't really work because theres nothing for the center punch to push against.
so my question is, how does one go about removing the old bearings ??
and the important is because i need to get to work in the morning >.>

New bearings can always be "carefully" hammered on .
Getting the old ones OFF requires (I believe) a "guillotine" style bearing puller (don't know if that's its technical name or not?!) ... basically, the puller has two tapered halves that go in behind the bearing, and those two halves get tightened together and the taper works a gap between the bearing and the face behind it. Then there are attachments to the two "guillotines" that do sort of the same function as a regular puller (pull the bearing off while the guillotines help separate the bearing away).
Since there's a big open space where the axles go through, leaving you nothing to push against in the center, slide a big screwdriver or something through the hole where the cross-pin would normally go (don't use the cross-pin, 'cause you don't want to bend it), then use a couple large sockets or something to take up the space, and create a surface for your puller to push against .
But if you were using the correct puller, the bearings may pop off before you really have to start "pulling"?!

my grandpa has a bearing press that I used. And my dad has a whole bunch of old bearing inner races to help removal/installation. I found one perfect that fit inside the bearing I was pulling off but rested on the carrier face where the axle slides through. It took a LOOOT of force to pull those bearings off. the side with the ring gear I couldn't fit a bearing puller.. all I could fit was a 2-jaw that slipped into those two small slots. I had the same setup for the puller to push against that old bearing race and a piece of scrap iron laying across the hole. But it still took me forever to get the bearing to budge. Once it did I finally got to fit the bearing puller in it and use the press but it took a **** ton more force then the other side. plus the 2-jaw puller kept spinning on me since I was torqueing it so much. Cabel1 is right though it'd be easier just to carefully slice the bearing away and chisel the last little bit off.
To put the new ones on heat the bearing on a hot plate or in the oven and put the carrier in the freezer or in some dry ice overnight, the bearing should slip on pretty easily.
