Pilot bearing vs. Pilot bearing removal techniques
And the winner is the Pilot bearing!!! After spending 3 hours this afternoon of using various techniques to remove a pilot bearing, I have given up. The pilot bearing won, and left me with various gashes in my hands. I even used a pilot bearing removal tool, and that didn't work! But it was only a 2 prong, and not a Mazdatrix 3-prong. Everytime I use the removal tool, it breaks the edges on the pilot bearing, so I gave up because I didn't want to destroy the bearing. I was able to get the seal out, and the inside of the pilot bearing out, but not the bearing itself. Any tips on how to remove this beast would be a great help. I would buy the Mazdatrix tool, but funds aren't allowing that now.

I got it out with just a regular two prong pilot bearing tool. Don't be afraid to **** up the bearing race as long as you don't **** up the shaft. I mean you're replacing it anyways.

I'll try to find my mazdatrix bearing puller. I'll mail it to you if you pay shipping and under the condition that you mail it back
It seriously took 1 minute once I got it.

i had the same problem on a friends car i was replacing the pilot bearing on. all the needles had came out so all that was left was the bearing race. it isn't bottomed out in the shaft. get deeper in the hole with the tool and grab it on the far side. that's how i got it out. and the one i used was only 2 prong, rented from advance.

Sorry I haven't got a pic for you yet. Been busy.
Here is what you do:
Take new pilot bearing to hardware store and find a washer with an OD that matches the OD of the pilot. The washer that I use (pretty sure it is a standard size) matches the pilot bearing OD almost perfectly.
Get a bolt that is about 3" long that is a size or two smaller than the washer you found. For instance, if the washer is made for a 3/8" bolt, get a 1/4" bolt instead. You want the hole big enough so that you have enough slop to line everything up. The nut that matches this bolt just needs to be big enough to not fit through the hole in the washer.
Tip: In the ~3" long bolt, try to get one that this threaded all the way up the shaft.
So, now you should have a nut, bolt, and washer. Now, you have to modify the washer with a bench grinder. Grind two sides of the washer so that the width of the washer is less than the ID of the pilot bearing. Something like this:

Now put the nut through the pilot bearing and then the washer (install flat and tip up into place. Line up the hole of the washer with the hole of the nut (this is where having the bolt/nut smaller than the washer size really helps out). Now start screwing the bolt into the nut. You may have to push while turning to keep the nut from just spinning. One it is started, the bolt will start to push against the eshaft and the tension will now keep the nut from spinning. Just keep tightening the bolt and the pilot bearing will come right out.
It may sound a little complicated in words, but it is actually really simple. Costs less than $1 to make (free if you have a good bucket of bolts/washers laying around). This way is probably just about as fast as the OEM puller and will get out even really stuck bearings.
If you don't have access to a bench grinder to modify the washer, pm me your address and I'll drop mine in the mail to you tomorrow morning.

I also tried a puller from Autozone, but it was just too big/thick to fit in properly. After a couple of hours, I gave up and took the dremel to it. That worked fine.

So this afternoon I tried the 2-prong Snap-On puller, and it failed. I then tried the washer method described above by addict, and I bent 2 washers, so I've come to the conclusion, that the bearing is in there pretty darn good. So it looks like I'm going to bring out the dremel! Time to tear this sucker to pieces. Thanks for all the tips though guys, I'm sure this thread will help other people trying to remove a pilot bearing.

Hmm, I thought about that a little bit. I've heard of other people who've dremeled though. I'm just really getting frustrated. I talked to my one uncle the other day who works down the road at a shop, and he said dremeling would be good idea since it's in there so bad. Is there any other techniques I could use to get it out?

I had a bitch of a time getting mine out a couple months ago. I tried the grease. I tried making my own tool. Nothing worked. I eventually found a place that sold a cheap ($24) three prong bearing removal tool. I had to file down the ends of the prongs a bit to enable a good grab on the bearing race but it eventually worked.
One tip for you. I had previously removed all the needles so I was able to position the jaws of the puller on the lip of the race that is closest to the opening (so not all the way to the back of the hole). For some reason it kept slipping off when I tried to get a hold of the far end of the race.
Good luck. I feel the pain.
