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?
