    have started to sort my rear bearing but the bolt is well rusted and there is nothing to get hold of.

    I dont have a suitable 12 point or spline bit to hammer in and was thinking if I remove the wheel I could weld a nut/bolt on the end of the stripped hub bolt.

    never fecking easy!

    question:
    any other options?
    if I do go down the welding route do I really need to disconnect battery/alternator/ECU or any/all of them?

    i dont think a hammered in spline bit would work anyway, its just too tight.

    Stick your 14mm hex in the hole and weld it on, then undo.

    Saying that, its bolted to the diff, which bolts to the shell.

    Unplug things if you want, i've welded bits before and didnt bother.

    I cant see how it can cause a problem, its a completely seperate circuit to any of the cars electrics.
