    The story begins with a welded diff in an E46 problem. I have a 318ci and broke the half shaft first night I got the welded diff in... In the rain. So upgraded to 320d shafts and cups. Lasted for months, now I've broke the cup. Problem is, I can't get the broken part out of the diff. I tried prying it out with the small lip that was left, no luck. Screwing a bolt in didn't work and just stripped the threads. Now I've welded a bolt on and it seems this thing is just not budging with any prying and banging I do. Any ideas would be great. May just have to take it to the mechanic to get on the lift and remove the diff to get it out.

    If you take the other half shaft out, can you punch through ?

    Chances are it's welded in, easy to get the end of them with the mig of not careful

    I've tried this with a spare diff I have laying about and should work... I just stripped the heads off the torx bolts. Waiting on spares and just cut them off and try punch them through.

    I think I'd leave this as a super last resort hahaha

    Is that groove around the end of the thread not for a circlip? Would there be on one the end holding it in place from the inside?

    Naw there's usually a seal on top but I exploded that too. You can usually just give it a few taps with a hammer and it should slide out.
