You'll need to squeeze the spacer to one side till one of the ears bends and there is a small clearance to fit a screwdriver and drive them out. Did this recently, prepare to be very patient. Also, make sure you have replacements in hand before doing this. There is a good chance they won't be reusable.

Yes, that spacer is between both bearings. There is 3 tangs on each side to hold it in place. You can just take a screwdriver and wedge that spacer to one side. No need to cram it way over - just enough so you can get that punch on the bearing. Just work that spacer around the bearing as you punch it out. Be sure to keep in mind which side is which on that spacer as I think one side is bigger. Once you get the first bearing out then take the spacer out and bend that tang back. I have never had to replace a spacer...just bend that tang back before you put it back in.

The Harbor freight blind bearing puller has worked like magico for situations like this on a few circumstances.

I made a puller from a concrete anchor. I ground it a bit on a bench grinder 'til it just fit in the bearing, tightened it to grab the bearing and punched it out from the other side. If you're interested, I'll get some pictures of it. If not, I won't.

I punched the bearing out with help of a plastic sledgehammer. Used a rod from a 1/2" wrench socket kit that hit the bearing after I had moved the spacer sideways with a screwdriver. Hub rested on wood parts. I had to hit hard and out it went.
A little bit easier after heating the hub in the oven.

Check how to mount the new bearings described in other threads on this forum.

That's how I do it.  I keep it my box of special tools.  Don't need it often but when you do it works great.  A little heat with a propane torch on the hub helps a lot too.

I tried that concrete anchor method, but no success.  I understand the concept, but i could never get it to bight well enough on the bearing. 
A good set of punches should be in every toolbox.  This is my preferred method

You will find several threads on this topic if you do a search. I assume you have taken the threaded retainers off, if not there are several homemade tool options if you search.

Probably the the best method for driving out the bearings is the first post. Bend down that spacer and use a rod to tap out the bearing by hitting it in several places working your way around. You can use some heat to expand the aluminum which helps a lot both in removal an install.

Take your bearings and races and put them in the freezer over night, heat the hub and you will find everything goes in without much violence.

I actually take the old bearing and set it on the new bearing and just tap it in. No damage to the new one and good to go.

I removed bearings honestly with heat from a moving torch heating the hub portion (NOT THE BEARING).....again DO NOT HEAT/MELT BEARING.....when you heat the hub it expands allowing the bearing to be removed easier....it does take about a min or two of heating depending on old and stuck the bearing is....for me...they were the original bearings and i turned into Thor knocking them out but they came out....

Thanks everyone. I just bent the tabs and smacked the bearing right on out.

[BobbyR]

Easier that you thought it would be. Now it you get those bearings really frozen and you warm  the hub they will almost fall into place.

I also used the concrete anchor from home depot, I forget the size but I filed down one of the
Bumps and it wouldn't bite.  So I wedged the tip of sharp awl in there to take up the space and it popped right out with just a bit of a whack on the end of socket extension.
