Ok, so heres what was going on..........I started hearing a clicking sound about a month or so ago while turning, and I've been keepin the car in the garage waitin for a weekend to work on it. Took it out and it was makin worse sounds, bad metal-metal contact sounds. Ended up thinking it was the CV joint was gone so I took it over to a friends house where he was gonna take a look, see what he thought. To make a long story short, we started takin the wheel off and took the rotor off and found this:

Part of the bearing

behind the rotor. So obviously we had a problem started by takin off the toe hub which is designed really weird with the race in the top. Anyways we ended up havin to get a puller to get 1/2 the bearing out. It pretty much fell apart completely, the bearing race is missing, and the other 1/2 of the bearing is pretty stuck. So today i'm waitin on my friend to get home so we can head out to his dads shop and get a hydrolic press on it, we've tried everything and ended up with just the outside of the bearing stuck in the hub. So we're kinda stuck, and to get just this far has taken almost 7 hours yesterday, bearing was seized onto the shaft, its been a real cracker to even get the spindle (i'm callin that the piece with the wheel studs) out from the rest of the hub to get to the bearing. So wish me luck tryin to get the rest of it out and press in the new bearing (using the handy vice). So yea thats my rant, anyone have any ideas let me know, if i dont get the rest of this bearin out i'm gonna have to find a new toe hub assembly (maybe w/a good bearing!). Still dont know how this can happen to a sealed bearing, but i guess stuff happens whether or not its expected.



Thanks

having a hard time reading your post... Which part of the bearing are you having a problem with?



The outer casing where it seats against the aluminum "triaxial" floating upright? (that is what mazda calls it in their manual)



Or are you having problems with the inner race that is stuck on the hub which is splined internally?



For the first one... I had to make a puck on the lathe out of some scrap metal i had lying around and put it on a 10 ton hyrdualic press. The puck needs to be just a **** hair smaller in diameter than the outer race.



For the inner race stuck on the hub with the internally splined shaft. That ones is a bitch. I held the hub in the vice, got the oxyace torch and heated the race. I then immedaiately got a chisel and smashed it where the race butts up against the hub and it moved it slightly off. I applied a bit more heat and knocked the race out a bit each time until I could get a 3 jaw puller on it. I then applied heat (quick short bursts) at certain areas around the race while using the puller.

And safe too. The fact that you can't get part of the bearing off is a blessing in disguise, just buy a used part like Banzai suggested and install the new bearing(s)

Thanks for the replies, we ended up gettin it off w/a 15 ton hydrolic press and the new bearing went in like butta. Thanks to Sage from DEI for helpin me work on it, we're now back on the road and on to the other problems. I now know way more than I ever thought there was to know about that hub assembly.



Thanks
