    Damn rusted in bearings.. how to get out?

    They broke apart upon removal, so now just the outside race is stuck in the hub (one on each side).

    There is an internal ridge in the hub that wont allow me to reach through from the other side to push them out.

    Been soaking them in WD for days, still no luck trying to get under them to pry them out.

    Is my best bet puting a cut off wheel on a dremel (which I dont have) and cutting them out in pieces?

    You may need to use a "blind bearing puller".
    Probably easier to just take the hub somewhere that they have that kind of tooling, machine shop, transmission shop etc.

    take the hub and freeze it in the freezer overnight or for a couple hours, then try to pry it out and beat it, then if that doesnt work, while its still cold heat it up in the oven or with a torch

    Also, 84/85 have some internal snap rings in the front hub.

    If you heat it in the oven, make sure you preheat at 375 degrees for 15 minutes.

    I had the same trouble with multiple bearings. My father taught me this trick. Take a steel bolt short enough to stand up in the race, like->(/), and weld it in place. Let it cool and use a suitable and long punch and pound it out from the center of the bolt. If the weld breaks then reweld it and repeat. It will come eventually.

    You might be able to use a dremmel and cut notches in the race that is left and bend them up. I'm unfamiliar with a T3 hub so there might not be enough room.

    the easiest way to get them out is find your local auto shop,, you need a inside jawed slide puller it will pull them right out without any damage!!!

    Do you have an air compressor? If you do, buy a short barrel impact punch, it will pop those baby's right out.
