    I have a 12bolt rear end and it is leaking between the axle tube and the pumkin. What do I need to do to repair this?

    The only way I know of is to have it welded. If you have the tubes welded to the pumkin it will also make it stronger.

    it's actually coming through the joint between the axle tube and the pumpkin????? Thats very odd. If you do weld it remember that the pumking is cast and you will have to heat it up before welding it to the tube. - Doug

    I've always heard it will be weaker because the axle loses its temper when you heat it up.

    You're right, but ya gotta do what ya gotta. Your not heating a whole lot, just a small area. Just don't poor water on it like an idiot after you weld it because it will make it worse. When they temper metal they heat it, drop it in water, than heat it a little less than before (it will reach a certain color at the desired temp). This way tempered metal is strong, yet flexible.
