I haven't taken apart any bearings on the e70 yet. I have done many on e53 though.
I only pushed the axle out far enough to get the bolts out holding the bearing. The tis calls for disassemble the swing arm to get the axle out completely. Are you replacing the bearing and hire bad is it? You can drive 1k on a bad bearing I had a customer drive like two years on a bait damaged bearing sounded like a UFO landing in his back seat.
You can use heat since you are replacing bearing.
Just don't make it red and lose hardening.
I don't recall if axle fits thorough the knuckle. Off it does you can pull the whole axke with the hub and use a press/large vice and hammer to push out the CV. What a job.
How long you where you are I could send my rotor disk and 1" bolt. You'd most likely laugh like I did when it took not twenty seconds to push out my stuck front axle. I also have a custom tool for cleaning the hub for reinstallation.
The tool for the hub is made from an old axle in case you have one. It's made from the very axle mentioned above that I mushroomed by pounding on it for 90 minutes.
